Ladybirds are to be encouraged (with the exception of the harlequin ladybird) as they help control pests such as aphids (greenfly and blackfly). Aphids ‘drain’ nutrient rich sap from host plants and also spread viruses with their piercing mouthparts. Some ladybirds add to their diet with nectar and as they sip nectar from flowers, they may also carry pollen from one flower to another.  Like many other insects, species of native british ladybirds have declined in recent years, many outcompeted by the harlequin ladybird (which is an introduced species from Asia.  Harlequins also harbour a fungus which can infect native ladybirds). [caption id="attachment_39002" align="aligncenter" width="675"] a ladybird 'stalking' aphids[/caption] Ladybirds are coccinellid beetles.  They belong to the order – Coleoptera – and are characterised by having forewings modified to form hard wing covers (ELYTRA) and they have biting mouthparts (as compared to butterflies and moths, which have a proboscis*).  Their wing covers are brightly coloured, and they serve as a warning to predators of their bitter taste. Ladybrds can also exude a pungent fluid to ward off ants, birds and people. Recent work at Cornell University (and the Lost Ladybug Project) has suggested ways in which ladybirds might be encouraged in the garden.   Strategies that might encourage ladybirds include : Growing plants that have hairs on their surfaces that offer some protection from predators,  Plants that 'offer' food such as nectar , or prey (aphids).  For example, aphids are often to be found on roses which frequently are home to aphids. Plants that give visual (or chemical) cues. More ladybirds were observed on the plants from the Umbellifer,  Daisy and Rose families  They seem to be drawn particularly to yellow flowers.

The first few weeks of owning a patch of woodland feel like the beginning of a long and special relationship. Every discovery is new; each adventure a first. A wood reveals it secrets slowly.   We’ve already tramped round every corner of the wood, tearing our shins on brambles, sniffing at fungi, clambering round stumps and totting up the oak, hazel, maple, cherry and rowan that thrive under our canopy of pine and larch. We’ve sat and looked and listened in all weathers, at every time of day. Starting a list of birds was the first thing to do: a mewing buzzard overhead, marsh tits pitching in the roving tit flock, the tap of woodpecker and nuthatch. Autumn – though this year so mild and late – soon announced itself with a first skein of pink-footed geese calling high and unseen over the wood, the first redwing chattering at the wood edge… sounds and colours change; the big wheel keeps on turning… We have always loved moths, for their beauty, their ubiquity, their astonishing variety. Moths range in size from the tiny micros whose larvae leave scribbled signatures across the leaves in which they live, to the powerful hawkmoths or that mythic blue-underwinged beauty the Clifden Nonpareil, a creature practically the size of a small bat, and probably the most sought-after moth among the old collectors with, in some years, just a single individual found across the country. For there’s also a rich and often eccentric history of moth recording in this country with most of the larger moths – the macros - having evocative vernacular names (though don’t confuse your Bright-line Brown-eye with a Brown-line Bright-eye!), and an array of techniques for acquiring them from pupa digging, plastering tree trunks with mixtures of treacle and rum, to light. Nowadays, moths are generally photographed and released rather than pinned; recording them is an excellent way of assessing the biodiversity of a site or tracking population changes. It was clearly time to break out the old moth trap.   And so it was that this September for the first time in years we dusted down the generator, filled the trap with fresh egg boxes for the anticipated moths to settle on, spread out our white sheet in a promising looking glade, and hoped to goodness that our 125W mercury vapour bulb would still fire up after all these years… As night came the light shed unfamiliar shadows through the wood; we waited, net in hand, taking care not to look directly at the blazing UV light; waited with a palpable sense of anticipation… what secret would the wood reveal? At first, nothing. And then a first furtive fluttering across the clearing to the trap – probably a Common Marbled Carpet though I’d have to check – and a plumper-bodied moth, and me there wracking my brains: it’s a noctuid, sure, but I’m so rusty – what’s-it-called? Flame? Flame Shoulder? Setaceous Hebrew Character…? ‘What the hell was that?’ said Beth Something ridiculously large had flapped out of the shadows and vanished. Knelt at the trap, I’d glimpsed it too from the corner of my eye. Could it be a hawkmoth on our very first trap, that would be very cool! I grabbed the net; we stood back and waited. I knew we had something beyond the ordinary when Beth yelled ‘There it is!’ and I swung the net and captured it on a second sweep. It was big all right! Anxious not to lose our catch, whatever it was, we shut ourselves in the toolshed and peered into the gently-opening net with our torch… The moth was the shape of a vulcan, practically size of a small bat, and more beautiful than anyone can do justice to: a marbled, lichenous beauty, zig-zagged and pocked and dabbed with greys and whites and blacks and – look! – when those forewings flick open an underwing black and banded with an impossible flash of blue… ‘It’s a Blue Underwing,’ we cried, ‘A Clifden Nonpareil…!’ An entry in my Aurelian’s Fireside Companion describes the experience soberly: ‘For a moment or two we gazed at it in speechless admiration, fearing almost to breathe lest it take flight…’.  I suspect we used a few more expletives than that!   And what a secret to reveal; our first trap in the new wood and we caught probably the best moth we could ever hope to find. One truly without compare.  Soon after the generator packed in; we were plunged into darkness. 2022, it transpires, has been a record year for Clifden Nonpareils, as it has been for many rare moths. Our Nonpareil could have been a wanderer from further south in England where a population has now reestablished itself on aspen and poplar after decades of extinction – or (and I find this the more romantic possibility) it could have been a migrant from the east, flapping its way across the North Sea to our northerly inland wood, and revealing itself, albeit briefly, to its astonished and delighted admirers…  By torchlight, we placed the moth on a tree stump, astounded to see something we’d always dreamt of finding. It sat there for a moment, as though contemplative, then showed a flash of blue petticoat as it shivered its huge and brindled grey wings. Shivered again. And flew off into the night. What will the seasons bring?

A fungi fanatic with a camera and a macro lens is never bored outdoors. At least, that’s how I tried to console myself when left stranded at a rural train station in East Kent having just missed my hourly train by a matter of minutes and realising that the next one was delayed by a further half hour. A brief wander around the environs to kill time proved me right when I came across a cluster of small grey mushrooms getting up to 2cm in cap diameter growing amongst the moss on a raised grassy patch at the far end of the platform. The mossy substrate, the indented cap and the widely-spaced gills running down the stem made identification a relatively straightforward business – these were part of the Arrhenia genus, which depending on the species can adopt either a pleurotoid (literally “side-ear form”) form, like the soft brackets we see with oyster mushrooms, or an omphalinoid form, from the Greek word ‘omphalos’ for belly button, with a central stem and decurrent gills running down it and an umbrella-shaped cap with a deep central depression.  [caption id="attachment_39104" align="aligncenter" width="675"] The Moss Navel in classic omphalinoid form with an indented cap and decurrent gills.[/caption] Looking at the spores back at home under the microscope corroborated the initial suspicion that these were Arrhenia rickenii, the Moss Navel, which according to its entry on the First Nature website is “a rarely recorded species, probably due at least in part to its small size and the tendency to be obscured by mosses” – and the fact that it is found in such nondescript liminal places as rural train stations, no doubt. There are numerous species of fungi that can be found growing on moss. Let us for now, however, ignore the tiny disc-like ascomycetes and other even more microscopic “bryophilous fungi” in which the interest is so niche that any information is limited to such specialist sites as this one, and instead focus on a handful of the more obvious mushroom-shaped ones. Most sources will refer to mushrooms such as the Moss Navel as saprophytic, meaning they derive their nutrition from decaying organic material, but with many species associating exclusively with particular species of mosses, many suspect this relationship between fungi and host is probably more complicated, as I alluded to in last month’s post on waxcaps. Yes, to know your bryophilous fungi, you often have to know your bryophytes. And what better place to start than following this link to The British Bryological Society... [caption id="attachment_39105" align="aligncenter" width="675"] The widely-spaced decurrent gills of the Moss Navel.[/caption] The initial issue I had with identifying my find was that different Arrhenia species are found alongside different mosses, and sometimes even lichens. Arrhenia peltigerina, for example, is found alongside the leafy Dog Lichen (Peltigera species), and hence its common name is the Lichen Navel. Arrhenia spathulata, a pleurotoid gill-less species known as the Spatulate Oysterling, is restricted to the moss Syntrichia ruraliformis (“star moss”) found growing on sand dunes or similar environments. The Moss Navel is not so fussy, it seems, which would probably make it one of the more common Arrhenia species, as is the case with another much smaller and orange-coloured omphaloid, the Orange Mosscap (Rickenella fibula). Actually both of these species were once considered, by dint of their shape, to be part of the same genus, with the Moss Navel previously known as Omphalina rickenii before its renaming to the current monicker in 1989, and the Orange Mosscap referred to as Omphalina fibula. [caption id="attachment_39106" align="aligncenter" width="675"] Orange Mosscap[/caption] The Orange Mosscap is a mushroom that is easily missed and just as easily misidentified, with a cap diameter of under a centimetre and often much less than that. Unlike Orange Mosscap, it isn’t just restricted to grassland mosses, such as those found in areas such as damp lawns and graveyards, but is commonly found on moss-covered tree stumps or fallen trunks.  While the cap and stem are orange and slightly translucent (the cap can wash out to a paler colour with age), the gills are white, and if you can get a close enough look at them using either a hand lens or a camera macro lens, you will notice that they are strongly decurrent, running down the slender stem and giving the whole mushroom a nail-shaped form. When up close and personal like this, one will also note that both cap and stem are covered in tiny bristles called cystidia, which are relatively large sterile cells found in the fruit bodies of gilled mushrooms that can aid identification. [caption id="attachment_39107" align="aligncenter" width="675"] The upper cap surface of the Orange Mosscap, covered in fine hairs that can also be seen on the stem.[/caption] The main lookalike mushroom that one is likely to confuse the Orange Mosscap with is the Orange Bonnet (Mycena acicula), whose orange cap ironically makes it the one of the most distinctive of the very difficult Mycena group of mushrooms to identify (see my previous posts on Frosty Bonnets and Rosy Bonnets).  The Orange Bonnet is quite a common find, and again very small, but while it is found in mossy areas, it is deciduous leaf and other woodland litter that is its substrate rather than the moss itself. The cap is pruinose, meaning with a dusty surface, rather than distinctly hairy, but it is the gills one needs to look at – these are adnexed or free rather than decurrent, meaning they are not attached to the stem at all. [caption id="attachment_39111" align="aligncenter" width="675"] The underside of the Orange Bonnet, with the adnexed gills distinguishing it from the decurrent gills of the Orange Mosscap.[/caption] Both Orange Mosscaps and Orange Bonnets have white gills and leave white spore prints, which will distinguish them from the final group of mushrooms to which they might be compared, those in the genus of Galerina. Many of this group fall within the LBM (‘little brown mushroom’) category that most mycologists and forages choose to overlook due to their insignificant size and nondescript appearance, but a few, such as the Moss Bell (Galerina hypnorum), the Veiled Bell (Galerina calyptrata), the Dwarf Bell (Galerina pumila) and the Hairy Leg Bell (Galerina vittiformis) among others, do have small orange caps and are found growing among similar mosses and mossy areas as our previous examples. These posts, incidentally, are not about foraging, but even though these mushrooms are not of a size to make them culinarily worthwhile, I would strongly advise against anyone ingesting them in the vain hope of some other form of more spiritual nourishment. Many Galerina species contain potentially deadly toxins, most notoriously the aptly-named Funeral Bell (Galerina marginata). [caption id="attachment_39110" align="aligncenter" width="675"] The dusty ‘pruinose’ surface of the Orange Bonnet.[/caption] The stem characteristics will provide some help of distinguishing the aforementioned Galerina species from the Orange Mosscaps and Orange Bonnets, and to some extent from one another – they are a lot more fibrous, many with white fibrils running longitudinally down the stipe, and some species have distinct rings around them beneath the cap. The bell-shaped striate cap also marks them out from the omphaloid characteristics of the Orange Mosscap. [caption id="attachment_39109" align="aligncenter" width="675"] A grassland Galerina in moss, possibly a Hairy Leg Bell. Note the fibrous stem and orange gill colour.[/caption] But again, and one cannot emphasise this enough, the best way to work out what you are looking at is to go straight for the gills and spores. Galerina have light orange to rust-brown adnexed gills, neither white nor decurrent, and if you leave them on a piece of paper to get a spore print, the deposit will be accordingly orange to brown, not white. And the fail-proof way of characterising any of these would be to look at the spore size and shape using a microscope and compare against other references such as the First Nature website. This post is essentially an ode to moss and all that live amongst them, to a substrate that in the dampness of Autumn provides a rich host for a number of species and which one might well want to take a closer look at when seeing what’s about in the woods or pastures.

The results of this year’s Big Butterfly Count have now been published and the ‘top’ 5 butterflies are the gatekeeper, the large white, the small white, the meadow brown and the red admiral.  The count is a UK-wide survey that aims to provide a measure of the state / health of our environment by simply counting the number and type of butterflies (and some day-flying moths) we see in our gardens and parks. The good news is that the Gatekeeper is making something of a comeback, being the most spotted butterfly in the count.  The numbers of the Common Blue, Holly Blue and the Comma are also ‘on the up’.  The Comma has been making a slow comeback for some years.  This is associated with the Comma extending its range northwards.  Extension of range is also seen in the Holly Blue, it is thought to be associated with climate change.  Some twenty years ago, it was rarely to be seen in Scotland, but it was recorded in Edinburgh in 2006, then Ayr in 2008 and now has spread across large areas of Scotland.  [caption id="attachment_24954" align="aligncenter" width="600"] Comma butterfly : photo by A J Symons.[/caption] The Jersey Tiger Moth is another species that is extending its range. Once it was to be found on Devon’s south coast, but it has spread north and east.  It is now to be seen in gardens and parks in the Greater London area. These moths ‘like’ gardens, hedgerows and disturbed / rough ground. In coastal areas, they may be seen on cliffs and the upper reaches of a beach.  The caterpillars of this moth feed mainly on ground ivy, white dead-nettle, bramble and the common nettle.    There are differences between butterflies and moth, but there is no hard and fast rule to distinguish between them. Butterflies usually have ‘club-shaped’ antennae, whilst many moths have feathery or tapering ones.   Butterflies normally fold their wings vertically over their backs,  moths generally place their wings horizontally when at rest (but not all). Whilst this summer’s results offer some hope, and the warmth of this summer’s weather might be thought to have favoured butterflies, the overall trend / pattern of butterfly numbers is one of decline - for example, numbers of the Red Admiral and Meadow Brown are down, sadly a pattern seen in many insect species. The loss of suitable habitats, such as meadows and hedgerows, is thought to be a major factor in this decline.

Our wood in the Scottish Highlands is an amazing place to go foraging for fungi. Last year we had bagful’s of Chanterelles so we hoped for the same when we went up last week. Like every owner we have met, we do not get up there as often as we would like, but we had great expectations that there would be tons of tasty toadstools, more “Chants”, some Boletes, maybe a Blusher or two and hopefully our favourite:  Penny Buns! (Ceps, Porcini are other names for them). We have a natural Birch Wood (near Loch Ness), with a few other tree species thrown in like Rowans, Juniper and some alien Western Hemlocks (good cover when it rains).  At this time of year when the Birches are on the turn, it is just glorious. The greens, golds and vibrant yellows are interspersed with the fading Purple Heather and the odd bright red Fly Agaric or one of the many Russula species adding further interest and detail. As usual, checking the trailcams was interesting, mainly Roe and Sika Deer. I have two there but forgot where one was....a common occurrence.   I found Hedgehog Mushrooms, some Scarletina Boletes, Birch Polypore and Chaga; the Chants were scarce but enough for a hearty breakfast.  I had all but given up on the Buns, but found a really tiny one hiding under the heather. There had been more but they had been eaten, some snipped off at the base and one fat one whose cap was gone and the stem mangled beyond use.  I had a suspect in mind; reviewing the trailcam footage at home confirmed my suspicions.    A Wild Boar ate my Buns!

In 1820, John Keats famous poem “To Autumn’ was published.  Its opening line often serves to describe autumn as ‘The season of mists and mellow fruitfulness’.  Indeed, Autumn has arrived here.  Woodlands have been transformed into a 'tableau' of red, yellows, and oranges as the leaves are shed and the woodland floor has become a veritable fungal jungle, (as Jasper has described).  Hawthorn and other bushes are laden with berries, conkers and acorns are generously strewn across woodland floors, squirrels are eating hazelnuts (and hiding them as a winter food store).  But this cornucopia of fruits and seeds may be in response to the long, hot and very dry summer we have experienced.  Trees and shrubs have been stressed by the heat and drought. Some have responded by mobilising their reserves / efforts into producing more fruits and seeds, to ensure that they pass on their genes to the next generation.   Different trees are responding in other ways. Some are ‘holding on’ to their leaves for longer, whilst others (like some birches and rowans) have already shed theirs - in order to limit the damage from wilting and water loss during the intense heat and drought of summer.  [caption id="attachment_39130" align="aligncenter" width="675"] Autumnal colour[/caption] Blackberries appeared early this Summer and few are to be seen this Autumn, some animals (like the dormouse) will search in vain. [caption id="attachment_39026" align="aligncenter" width="675"] Black Bryony berries (photo by Art Symons)[/caption] Will this Autumn be long and mild? It may extend into the traditional winter months. There is also the threat of extreme weather events (like Storm Arwen that brought severe winds across the UK last November).  Whilst we might welcome mild weather (with the high price of gas and electricity), it could be mean an increase in bacterial and fungal infections, not only of plants but also affecting overwintering insects - tucked up in cocoons and pupal cases. Prolonged cold periods, coupled with frosts limit the spread of such infections.  The cold of winter is also the traditional signal for animals like hedgehogs to hibernate.  If they are still active in winter when food is scarce, then they will lose condition and possibly starve to death.  Milder weather in Autumn and Winter also affects the migratory behaviour of birds, some birds may choose to overwinter here.  Some seeds need to experience cold temperatures before they will germinate in the following Spring. Climate change and severe weather events are here to stay until there is a coordinated and concerted effort to reduce greenhouse emissions on a global scale.  On a local scale, our gardens (which represent some 400,000 hectares of land) can make a contribution by encouraging wildlife / pollinators and promoting biodiversity.  Gardens can also help to some extent with extreme rainfall.  During heavy rain, water runs off hard surfaces and into the drains, these may also deal with sewage.  When the drains are overwhelmed by storm water, sewage is discharged into our rivers (and the sea).   Gardens can help by  reducing hard landscaping, so that rain can soak into the soil instead of running off into the drains making use of water butts.  They capture water, so it does not enter the drainage system.  It is also there to use when the garden needs water (and there is a hose pipe ban) mulching the soil with a layer of plant material. It is an effective method of conserving water in the soil and it reduces surface runoff, increasing the infiltration / penetration of water into the soil.  It helps keep the soil moist in times of drought, and helps reduce run off during heavy rainfall.  Particularly important when planting young trees / shrubs. [caption id="attachment_38957" align="aligncenter" width="675"] a light mulch (in Art's garden)[/caption]  

It is depressing to pick up a paper or turn on the news to be met with a catalogue of distressing and difficult stories.  There is also the overarching problem of global warning and climate change.  Only recently, there have been reports of flooding in Sydney after torrential rain, fires are springing up again in Colorado and other States, and India experienced a heat wave (combined with a drought), with some cities experiencing temperatures of 40o+C.  This has resulted in the deaths of individuals, and as the heat wave occurred in the final weeks of the wheat growing season it has killed many crops before harvest.  In Balochistan, the peach and apple harvest has been severely impacted. Here in the UK, there are a number of problems, indeed we have been described as “one of the most nature-depleted countries in the world”.  We have lost plant and animal species, such losses could lead us into an ‘ecological recession’. This occurs when ecosystems systems lack the diversity needed to function well. Much of the damage to (or loss of) our ecosystems is associated with the industrial revolution followed by the  intensification of mechanised farming. The 1950’s and 1960’s witnessed the loss of vast tracts of hedges and the removal of small copses to increase the area for farming / food production, and allow the use of heavy duty mechanised machinery.  There was also the extension of road networks - motorways etc. and urban sprawl /development.  Though woodlands and forests were being eroded long before the industrial revolution; woodland, forest and pasture covered much more of the land than now. There were areas of ‘wilderness’ that were home to animals and plants that have long since gone or are now very rare - ranging from wolves, bears, to beavers and red squirrels. Whilst woodlands were and are havens for many plant and animal species, meadows and pastures have suffered too.  The PlantLife charity has suggested that the UK has lost some 97% of its wildflower meadows during the course of the last century and what remains could be under threat. Lowland meadows are rich sources of biodiversity, both plant and animal, they also store carbon in the soil and ‘knit’ the soil together, so that it is not subject to erosion. [caption id="attachment_38489" align="aligncenter" width="700"] A meadow, partly mown and partly 'wild'.[/caption] Many species are dependent on these habitats, but with the expansion of agriculture and construction of motorways - the landscape has become fragmented and many species cannot across the formidable barriers.  The Scottish primrose is now only to be found on the north coast of Scotland and Orkney, and some orchids are described ‘as just hanging on’.  Species like the common blue butterfly is reliant of bird’s foot trefoil, Greater Bird’s-foot-trefoil, Black Medick and white clover for food for its caterpillars.  The great yellow bumblebee is sadly now one of the rarest British bumblebees. It is limited to flower-rich areas in the Orkneys, Caithness and Sutherland. It is particularly associated with red clover. It is a large species, and was once widespread across the U.K. Creating space and opportunities for wild flowers has been PlantLife's foremost objective from “No mow May”, “Save nature on our roadside” (see the woodland blog here and here) ’Fight for sites” all of which aim to increase the number of sites for wild flowers and their pollinators to flourish.  The Scottish Government has been helping establish wildflower meadows at some of its national nature reserves - notably St Cyrus, Flanders Moss and Forvie, and they are working with PlantLife to create an action plan for Scotland’s grassland.  It is keen for farmers to be involved, offering areas of wild flowers on their farms.  By increasing the areas in which wild flowers (and their associated insects) can flourish, the connectivity can be restored (at least in part).  The creation of biological corridors allows plants and animals to move, which is particularly important in these times of climate change.  

We are now in the peak season for mushrooms and toadstools, and UK Fungus Day, this Saturday 8th October, seems as good a time as any to get out into nature and have a look at what’s around. But while this blog tends to be woodland related by the very fact of it appearing on this website, when it comes to the role of fungi in our wider ecosystems, it can be easy to miss the wood for the trees. Fungi might have a fairytale association with forests, but we all know that they do grow in other places. Take our most common commercially grown edible, for example, Agaricus bisporus – a fungi so familiar it goes by a plethora of common names, including common, white and chestnut mushroom. The British Mycological Society list ‘Cultivated Mushroom’ as it’s official common name, but when it is found growing naturally, it is almost always on grasslands of some description, just like the larger closely-related Field Mushroom (Agaricus campestris).  So let us take a temporary foray out of the forest into fresh pastures this month, where we shall focus on an eye-catching and particularly interesting group of grassland fungi whose importance to the natural world needs a lot more appreciation and investigation: the waxcaps.  Butter Waxcap (Hygrocybe ceracea) There’s a whole swathe of mushrooms one might see growing in fields and parklands and other grassy areas. Most are saprophytic, growing on decaying organic matter, like such well-known varieties as the Shaggy Inkcap and the majestic Parasol Mushroom, and you might see other types like the Egghead Mottlegill or the Stubble Rosegill growing in animal dung or among hedge cuttings or other organic litter at the edge of fields and pathways. The waxcaps, however, prefer “unimproved” grasslands, by which it is meant that the ground has been left undisturbed and has not been reseeded for some time, it is nutrient poor and has not been dosed with artificial fertilisers, and is most likely used as either permanent pasture or a regular hay cropping.  According to the book ‘Grassland Fungi: A Field Guide’ (2017), by Elsa Wood and Jon Dunkelman, such short-sward, nutrient-poor areas tend to be rich in wildflower species and a good moss flora is present. This latter point is important, because while waxcaps have been thought of both as being saprophytic and mycorrhizal (growing in association with plant roots), current research seems to suggest they grow in association with grassland mosses. Butter Waxcap (Hygrocybe ceracea) amongst the moss As such, waxcaps are incredibly useful environment indicators, and one of the key species types in a system known as CHEGD proposed by a certain E. Rald in Denmark in 1985 for evaluating the conservation value of a given grassland. CHEGD refers to five groups of fungi whose presence signifies a healthy grassland: Clavaroids such as club, coral and spindle fungi; the waxcaps are the H for Hygrocybe (literally meaning “wet head”); Enteloma, or pinkgills; Geoglossum, or earthtongues; and Dermoloma, a genus commonly referred to as “Crazed Caps”. There have subsequently been a few additions to the system and the taxonomical revisions that seem to regularly hit the world of mycology mean that Hygrocybe has been split into several other genuses that also refer to waxcaps, including Cuphophyllus and Gliophorus. Nevertheless, the name CHEGD and the principles behind it still stand.   Snowy Waxcap (Cuphophyllus virgineus) Unimproved grassland habitats are few and far between in some parts of the world, with many of our large, open areas given over to agricultural practices that favour the rapid rotation of crops, for example, or they are earmarked for building houses upon. Ancient grasslands might not get as much attention in environmental conservation and restoration as woodlands or even wetlands, but it is thought that the hyphal mats of the CHEGD fungi are likely good carbons stores in their own right which could easily be destroyed if ploughed or otherwise disrupted – so planting trees in grassland habitats might not reap the dividends in terms of carbon offsetting that some might have us believe. Village greens and graveyards are among the kind of environmentally unsullied areas one might expect to find waxcaps, but it seems the British Isles is rather blessed in terms of unimproved ancient grasslands, from the South Downs in Sussex to Hadrian’s Wall and in particular Scotland and Wales, from heaths to sand dunes and coastal slopes, and from hay meadows to roadside verges and the lawns of stately homes, as I discovered in a fascinating online talk given by Sean Cooch and Clare Blencowe this summer which was recorded and can be seen viewed here.  Meadow Waxcap (Cuphophyllus pratensis) As I mentioned in my July piece on the Beefsteak Fungus, we have quite a few fungi species in the United Kingdom which are relatively common here while rare on the European mainland, and we need to make more people aware of this, so that their habits are preserved and ancient trees are not chopped down or vital fields ploughed (such as with this regrettable faux pas by the National Trust last year). Habitat loss is key to the scarcity of the Date Waxcap (Hygrocybe spadicea), one of Britain’s rarest fungi, which is one of five species of grassland fungi that appear in the Section 42 list “Species of Principal Importance to the Conservation of Biodiversity in Wales”, meaning public bodies have a duty towards their conservation. It is the only waxcap on the list, which also includes Violet Coral (Clavaria zollingeri), Big Blue Pinkgill (Entoloma bloxamii), Olive Earthtongue (Microglossum olivaceum) and Dark-purple Earthtongue (Geoglossum atropurpureum). There are about 50 species of waxcaps in the UK, and while I’m not going to go into detail about them individually, the names alone should point towards their beautiful range of colours: Scarlet Waxcap (Hygrocybe coccinea), Snowy Waxcap (Cuphophyllus virgineus), Honey Waxcap (Hygrocybe reidii), Splendid Waxcap (Hygrocybe splendidissima) and the Pink or Ballerina Waxcap (Hygrocybe calyptriformis). Blackening Waxcap (Hygrocybe conica) I’m opting for the Blackening Waxcap (Hygrocybe conica) as my fungi of focus for this post, in that it is the most easily to recognise: while its sticky and distinctively conical caps start off in a range of colours between red and orange, as they age or are damaged, they blacken in a quite unmistakeable manner, eventually going completely black and looking a bit like a witches hat. It is also the most common, although now it is thought that rather than a single species, it is actually a species complex or a group of very closely related separate species. Waxcaps are most commonly found from mid-September to the first frosts in November. If the colours and textures of these beautiful fungi aren’t enough to get you out and about hunting, then like the Standing Oak Tree Fungus Survey I mentioned in my Beefsteak Fungi post, the Waxcap Watch Survey currently being conducted by the international conservation organisation Plantlife might provide further incentive to get involved in an invaluable citizen science project. A Blackening Waxcap beginning to blacken. No real mycological knowledge is needed for this. The basic guide is to find a suitable area and check it out for these CHEGD, and only record the number of different colours of what you find. Whether you find much or don’t, enter the results using the App downloaded from the website, and they will be recorded on this interactive map. Some sites might not yield much, but they will at least be marked on the map as a red dot meaning “not much was recorded at this site but it’s worth having a look another time.” In contract, Green will show a vast diversity of species, with orange somewhere in between. I’ve not entered any data myself at the moment, as I’ve not found anything yet this year, but whereas the evidence shows a great waxcap diversity of sites in Wales, Scotland and the Southwest of England, there is little evidence of anything in my surrounding area in Kent. This is certainly not to say there’s nothing there. In previous years I have discovered a good variety of waxcap species in the village of Keston, just outside Bromley, a Parrot Waxcap in the grounds of Walmer Castle, and Blackening Waxcaps aplenty in the reclaimed coal spoil site of Betteshanger Park outside Deal. I am clearly overdue a revisit to these sites to record these finds. The astonishing colours and textures of the Goblet Waxcap (Hygrocybe cantharellus) For those who wish to dig deeper into the subject, there’s a free downloadable PDF on the Plantlife website providing a basic guide to the identification and management of waxcap and grassland fungi, listing about a dozen species. A fuller range can be looked in this dedicated section in the fabulous First Nature website, and if the sheer number look a bit daunting, then you’ll be happy to read that the Sussex Biodiversity Record Centre has provided this online Grassland Waxcap Identification Support Tool. Clare Blencowe details her love of waxcaps and the process behind developing this tool in the Newsletter of the National Forum for Biological Recording issue 58. And finally, the University of Aberystwyth provide a wealth of information on their Waxcap Website. Hopefully this will spur some of you on to head out into the grasslands on UK Fungus day and beyond to record your findings for the Waxcap Watch Survey. This kind of data provided by citizen scientists could prove really useful in making sure our unimproved or “unspoilt” natural areas remain so, and while there’s never been a case of a mushroom stopping a housing development, building up a public awareness of what we have in this country is essential.
