Fungi seem to be enjoying something of a field day in the popular media at the moment. The 2020 documentary Fantastic Fungi, for all its faults, has fanned the flames of fascination in its subject since its appearance on Netflix last year. Startling stop-motion sequence of mushroom growth also made it into several episodes of Sir David Attenborough’s recent BBC series The Green Planet to highlight the centrality of plant-fungi symbiosis to our living ecosystems. This aspect has been thoroughly detailed in the field of popular science writing, with the highly-recommended Entangled Life: How Fungi Make Our Worlds, Change Our Minds & Shape Our Futures seeing the emergence of its author, Merlin Sheldrake, as the thinking man’s Paul Stamets when it comes to discussions of the Fifth Kingdom. There’s been a 3-part series, Fungi: The New Frontier, broadcast on Radio 4 in January, and a volley of no less than three articles appeared in The Guardian in November 2021: ‘The earth’s secret miracle worker is not a plant or an animal: it’s fungi’ by Giuliana Furci;  ‘A powerful and underappreciated ally in the climate crisis? Fungi’ by Toby Kiers and the aforementioned Merlin Sheldrake; and the announcement of an exciting new project in the report ‘World’s vast networks of underground fungi to be mapped for first time’. [caption id="attachment_36822" align="aligncenter" width="650"] ‘Ectomycorrhizal species like this eye-catching Fly Agaric perform a vital ecological role in our woodland eco-systems.’[/caption] Rather than a focus on a specific species this month, I wanted to offer a few thoughts, observations and suggestions about the hows, whys, and wherefores of learning more about  the world of mushrooms and toadstools.  As these examples demonstrate, the importance of fungi and both preserving and mapping its diversity is rapidly becoming a discussion point in the mainstream media, and as in other areas of nature recording such as butterflying surveying and birdwatching, the Citizen Scientist can play an important role in this. Reporting ones finds on wildlife observation websites such as iRecord or iNaturalist can provide invaluable information that can highlight how common a species is, both regionally or nationally, its favoured habitat, and how this might be affected by factors such as changing land use and climatic conditions. For example, I have covered a number of species in these blogs, such as the Crimped Gill or, more ominously, the Hymenoscyphus fraxineus fungi behind Ash Dieback, that were barely reported a decade ago but are now commonplace. [caption id="attachment_36823" align="aligncenter" width="650"] ‘Crimped Gills have become increasingly prevalent across the British Isles over the past ten years, but are still considered “rare” on the recording website iRecord.’[/caption] There is a major obstacle in all this though, namely that the domain of common knowledge about fungi is tiny compared with other areas of the natural world. Records with accompanying photographs submitted to these wildlife observation websites of birds, insects, molluscs or mammals are often quickly verified by those entrusted to do such things. Fungi recordings can go for many years without confirmation due to the lack of knowledgeable experts capable of undertaking such a task and a consequently mounting backlog of unverified recordings.  [caption id="attachment_36824" align="aligncenter" width="650"] ‘Tiny mushrooms such as this Bark Bonnet (Phloeomana speirea) can be throughout our woodlands all year round, but it often takes incredibly close inspection to confirm your identification.[/caption] Of equal, if not of more concern is the danger of the amateur nature spotter misidentifying and mis-recording their finds. It is better not to submit a record at all than an incorrect one, but as these posts have probably shown, identification is often a tricky business. A number of smartphone apps have arguably compounded the situation. Many fungi require close, even microscopic, examination to identify properly, something an app is never going to be able to do. Most only list the most common species, and no matter how powerful the algorithms powering them, they can often be miles off the mark. None, for example, would be able to distinguish from a photograph alone the difference between a Velvet Shank (Flammulina velutipes), and the other two Flammulina species that have been reported in the UK, Flammulina elastica and Flammulina fennae, nor the common Sulphur Tuft (Hypholoma fasciculare) with the Conifer Tuft (Hypholoma capnoides) or the Brick Tuft (Hypholoma lateritium). You would be on a hiding to nothing attempting to identify one of the numerous crusts of tiny disc fungi using such tools. [caption id="attachment_36825" align="aligncenter" width="650"] ‘A mushroom identification app will tell you this is a Velvet Shank, but only a microscope and a look at the host tree will tell you if it is Flammulina velutipes, Flammulina elastica or Flammulina fennae.’[/caption] Ready-fix solutions like phone apps have the drawback that they discourage people to put in the legwork of poring through identification guides, such as my 'go to bibles', Thomas Laessoe and Jens H. Petersen’s two-volume Fungi of Temperate Europe or Geoffrey Kibby’s 3-volume (with a fourth one pending) equally impressive Mushrooms & Toadstools of Britain & Europe, and of handling, smelling and generally scrutinising your specimens to really get to know your mushrooms.  Accumulating a library of books such as these can be an expensive business, but if you’re serious about getting into the subject, then the investment soon pays off (at least in terms of personal satisfaction rather than financial reward; mycology is alas a woefully underfunded area at the moment). If you are just getting started, there are also websites such as First Nature, and numerous Facebook groups with people willing to help out with your identifications. That is not to say I personally eschew computer-based solutions completely. The ‘Atlas of Danish Fungi’ website, affiliated with Laessoe and Peterson’s publication, has probably the best ‘Name Suggestions’ from a photograph feature I have come across. I have found it very useful when it comes up with a handful of candidate species to check against more thoroughly in the printed guides. [caption id="attachment_36826" align="aligncenter" width="650"] ‘Sulphur Tufts may be one of the most commonly found woodland fungi, but how many records have failed to distinguish it from Conifer Tufts or Brick Tufts?[/caption] What the recent flurry of media interest in fungi highlights, perhaps, is the huge disconnect between the scientific knowledge base and research, and the hive or folk knowledge exhibited by field recorders, many of whom have been at it for decades. In fact, so steep is the learning curve, getting newcomers interested in mycology and overcoming the mythologising and misinformation surrounding the subject is a real challenge. If your curiosity has been piqued and you wish to explore the subject further, firstly I would advise joining the British Mycological Society, and more specifically, contacting your local BMS affiliated Local Fungus Recording Groups, a full list of which can be found here. As the BMS themselves explain, “They are run on a voluntary basis by enthusiasts seeking to share their knowledge of wild fungi and improve your identification skills. Groups offer a welcoming environment for current and new members to enjoy exploring the world of fungi.” Joining up to your local group offers the chance to learn quickly what’s what in this fascinating field, as well as providing a nice social day out, and a chance to make your own contribution to a subject that is in much need of further exploration.

When we first had our wood, we didn’t worry about a toilet. “Go behind a tree” we told visitors. And the campers went off into the woods “prospecting” with a trusty spade. No problem.   But the years went by and we started to have visits from little girls, and older ladies, and we realised we were in trouble.    So we dug a hole. And over it we placed a large strong box, upside down, with a round hole in the top. And over the hole we fixed a toilet seat. On a post at the side, we hung a toilet roll. Simple, really. The rhododendron bushes were pretty thick just there, but for added privacy we erected a screen of dark cloth from the market, supported by poles.   And since that day, I have been collecting ideas from other woodland owners on the best way to do it: to be hygienic, civilised, and environmentally friendly. The best advice I had was to buy from the Centre for Alternative Technology a wonderful book called “Sanitation without Water” by Uno Winblad and Wen Kilama.  Tens of millions of people, to this very day, are surviving and flourishing, day in, day out, without toilets as we know them. And although none of us woodland owners expects to be in this sort of situation, the book has some very useful tips. “People need to choose the latrine that is best for their area and for their traditional culture.” Hence the toilet seat, which transforms the very primitive arrangement of just squatting instantly into something fairly acceptable. Though, as a ten-year-old said to me the other day, “That’s the weirdest toilet I ever saw”. The book recommends sprinkling dry ashes over excrement to prevent flies from getting to it, and this also much reduces the odour. We collect the old ashes before lighting the new fire, keep them dry in a big pot with a water-tight lid, and sprinkle them with a soup ladle.   Apparently, the mixing of urine with faeces inhibits the rotting which will naturally render the bacteria harmless. So we now follow the advice of the book, and spread a layer of vegetable waste, or just leaves, in our toilet each time we visit. Of course, the hole gets filled up, and when it is near the top, we cover it with a good layer of earth, and dig another hole. Moving our screen is fairly easy. Other people have told me they use a pail inside their box: one of those straight -sided containers used in wine making. Then they empty it in a hole far from the clearing where they picnic or camp. They actually have walls and a roof on their toilet; when it rains we just hold up an umbrella! Getting closer to the natural scheme of things, another owner showed us her “compost toilet” with logs arranged in walls round the four sides of the hole, and a nice smooth round one to the front for sitting on. She assures us it is very comfortable. Her screen is simply poles, tepee style, clad in branches.   A friend who visits frequently is slowly replacing our dreadful curtains with fine traditional hurdles, made from our own hazel.   And for a lock, a simple branch on stilts across the track leading to the toilet will suffice - after all no toilet in our own culture is complete without a lock, however notional!   This blog was originally published in 2006, but is often searched for - so we have brought it forward. Below is a link to another offering on the subject, from a woodland owner: https://www.themoonandthefurrow.co.uk/blogs/news/building-a-compost-toilet  

Recently, woodlands.co.uk asked me some questions about ‘buying a woodland’.  So here goes : How did you find your woodland? As a local, I found the woodland by walking with my partner and our dog. My partner’s family lived in the village for a number of years. Were there surprises you found in the first few weeks of owning your wood? The biggest surprise for me in the early weeks was the expansiveness of my woodland, every time I would visit I would find something different. This could be a different tree species,a path or a bird. Did you set up a campsite and how did that go?   One of my goals was to camp at least once a month, starting with my first month of ownership in January! Camping has given me the opportunity to spend more time in the woods, not just mornings /  afternoons and appreciate the peace and quietness. How have you managed the woodland?  Management so far has been cutting overstood hazel coupes for regeneration and collecting good firewood for home. Rotten or poor-quality wood has been collected and stacked for wildlife habitats, especially oak! The hazel rods have been for craft activities ,with the brush piles being left for insects. What are your future plans for the woodland?  Future plan for the woodland is to introduce different native species of tree. I have around 20 saplings I have potted on at home, that will eventually be moved into the wood. With the regeneration of hazel, the crop I intend to use to create deadwood hedges for protecting young trees from deer. How have various members of the family got involved in the woodland?  All of my family have visited the woods and helped in some way. Whether it be firewood, coppicing or bringing food to have with a hot drink!   What practical projects have you done or planned for your woodland?  How did you do these?  My partner and I both enjoy wood craft such as pyrography and woodturning. A lot of oak limbs that have come down during storms have been used to make presents for friends and family, and decorations for our home. What advice would you give to someone buying a small woodland?  My best bit of advice would be to wait for the woodland that has what you want. Woodlands come in all shapes and sizes; and getting the right patch can make your experience a lot more enjoyable. In terms of flora, what have you learnt in the woodland? I have learnt that woodlands like mine (broadleaf) provides a home for hundreds of plants, flowers and insects. The humid conditions in oak woodlands provides ideal conditions for rare / hard to find flowers such as orchids and so many types of fungi and lichens. David 

A thousand years ago, significant areas of the country were devoted to wood pasture, that was grazed by livestock.  As time passed, much of this became royal hunting forest - a mixture of woodland, coppice, open land and farms.  As the woodlands were managed (through traditional techniques such as coppicing and pollarding), many of the trees were able to grow to maturity.  They became veteran trees.  Trees such as beech reach maturity after some 200 years, oaks take 400 years and yew 900+.   Such veteran trees can be seen in areas like the Savernake (south of Marlborough) and Sherwood Forests. Saverrnake has veterans like the Big Belly Oak, and Sherwood has the Major Oak.  Sadly, since the nineteenth century many veteran trees and ancient woodlands have been lost due to the expansion of agriculture, housing development and road & rail creation.  Veterans have also been lost from hedgerows, many of which were grubbed out to enlarge fields to allow for increasing mechanisation. As oaks and beeches age so they change, they expand, trunks hollow, cracks and holes appear, heart rot develops and dead wood appears.  Each tree offers a myriad of micro-habitats.  Bracket fungi feed on the dead heart wood, as do stag beetle larvae.   Mosses and lichens live on the bark, attached to crevices that channel the rain down the trunk, bats, woodpeckers and nuthatches inhabit holes. Other birds (like redstarts) nest in the branches and twigs.  The decaying leaf litter beneath the tree offers sustenance to a variety of beetles, and fungi (e.g. oakbug milkcap).  English oaks are associated with more than two thousand species, and more than two hundred are directly dependent on the trees. The loss of so many veteran trees has resulted in an international project to determine if these trees can be ‘replaced’.  It involves a technique termed veteranisation. Younger trees are damaged in order to start the process of decay and ‘ageing’.  The process may include Creating woodpecker-like holes Creating nest boxes for birds / bats Breaking branches Damaging the bark / trunk - to simulate deer / animal damage Inoculation with fungi It is being trialed at some 20 different sites in Norway, Sweden and England.  The project started in 2012 and will run for some 25 years.  It is hoped that such ‘techniques’ could be used to accelerate the formation of veteran trees status with its associated biodiversity.

Compared to past centuries, we live in a bright, highly illuminated world where even our nights are bright.  Apart from the lights in our homes and offices, there are thousands of street lights. In many places, the natural 'night time' environment is no more.  This 'artificial light' pollution  has increased significantly in recent times (as indicated by research led by the University of Exeter).    Street lights, especially the newer LED ones, may be affecting various night flying insects.   It is a fact that insect populations in general are under threat from  The loss of woodlands, forests, heathlands and meadows (often to agriculture) The intensive use of pesticides Climate change / extreme weather events Pollution of rivers / lakes (eg. Nitrate / phosphate pollution leading to eutrophication). Now the intensive use of artificial light is thought to be affecting night flying insects, such as moths. Moth populations are in decline, for example, the Buff Arches population, has declined in number by 62% since the 1970s. However, the effects are not limited to moths but also birds, bats and wildlife that feed upon them (or their caterpillars). The UK Centre for Ecology and Hydrology suggests that streets bathed in light may:- Deter nocturnal moths from egg laying. Make the night flying moths ‘easier targets’ for predators (such as bats). Affect the feeding habits of moth caterpillars. A number of investigations have been initiated by CEH, Newcastle University and Butterfly Conservation. The work involved surveys of grassland and hedgerows in southern England (Thames Valley) some lit by streetlamp, others unlit.  The areas that were exposed to night time lights had roughly half the number of caterpillars as compared to the unlit areas; (the hedgerows reduction was 47%, and 33% in grass margins).  In another investigation, LED lighting was set up in fields, caterpillars numbers in such fields were reduced.  It would seem that night time light affects the feeding behaviour of caterpillars. Quite how and why is to be determined. LED lights are being using more and more, as they are brighter, cheaper to run and more energy efficient. LEDs emit more blue light than older forms of lighting. It is likely that the impacts of light pollution on night flying insects will increase. This, in turn, will effect of other species, such as hedgehogs which need many, many caterpillars to feed themselves and their young.  The loss of insects, such as bees, ants and beetles is occurring at a worrying rate, indeed faster than the loss of mammalian, avian or reptilian species.  The loss of insects has far reaching consequences for ecosystems - as they provide food for many vertebrate species and they acts as pollinating agents for many flowers and crops.   https://youtu.be/Rnsz7JtBmJw

Reports on pollinators. Research by workers at the University of Reading and the Centre for Ecology and Hydrology has shown that various ground level pollutants (nitrogen oxides and ozone) have significant effects on the pollinating activities of bees, moths, butterflies and hoverflies.  The number of flower visits by these insects declined, as did the level of pollination and seed production. The University of Göttinggen has published a study that bumblebees need a diverse pollen diet, collected over a variety of habitats.  A varied pollen diet contributes to better colony growth, more offspring (particularly young queens).  It also helps offset the effects of infestation with wax moth larvae.  Wax moth caterpillars feed on nest debris, but as they grow they switch to feeding on the food stores and even grubs / larvae, effectively destroying the nest. Recent work by an Irish postgraduate student on insect pollinators in Dublin suggests that a “less is more’ approach  might be effective when it comes to natural green areas in cities.   Emma King looked at the pollinators present in Areas of planted meadows or sown with wild flower mixes. Areas with reduced mowing that were allowed regenerate naturally. She found that though insects like bumblebees and hoverflies were more frequently recorded in planted meadows, statistically there was no significant difference in the numbers; and the community of pollinators was similar in both types of green areas.  The advantage of allowing green areas to develop naturally is that it reduces labour and material (seeds) costs.  They may take a bit longer to establish a diverse flora but they will offer resources to pollinators. Such green spaces promote habitat connectivity within the urban environment. Sunflower update Work by staff at the University of British Columbia has revealed that sunflowers (like many other flowers) helps bees to visit by invisible (to us) ultra-violet patterns - usually in the form of a ‘bulls-eye’.   They observed that sunflowers growing in drier conditions had flowers with larger UV ‘guides’.  Furthermore, it was found that a particular gene was responsible for the nature of the bulls-eye pattern, and this gene was also associated with the production of flavonol compounds.   Quite how the gene and the production of flavonols is related to the capacity of sunflowers to retain water is not known. [Full details of the work of Dr M Tedesco et al here].

Wetlands. In the past, many areas of wetlands have been drained and ‘dried out’.  Now it is recognised that this is counter-productive in terms of carbon storage / sequestration and biodiversity, so there are now measures to restore wetlands. The hope has been that restoration of wetlands will do much to restore the variety of plants and animals (and help carbon storage).  However, research by the University of Copenhagen suggests that such projects might be ‘struggling’. The study examined ten wetlands (near the River Odense) that were restored between 2001 and 2011.  The restoration involved the removal of drains and ditches, and allowed streams to meander again instead of flowing in ‘straight channels’.  The aim of the project was primarily to reduce the leaching of nitrogen and phosphorus from adjacent farmlands, and hope to see greater diversity of plants (e.g. marsh orchids, globeflower, tussock-sedge and ragged-robin).   The ‘restored’ wetlands were botanically poor (whether restored in 2001 or 2011), they had only a quarter of the plant species compared to natural wetlands.  This may be due to  the continued input of nutrients (from agriculture), which encourages species that are ‘nutrient hungry’ at the expense of others. the ‘difficulty’ of wetland species to disperse from one area to another. It may be that future restoration programs will need to include planting / seeding of additional wetland species. It has been suggested  that it could take the best part of a hundred years for the restored wetlands to resemble natural wetlands. Redwoods and relatives. Previous posts have talked about the special features of the giant redwoods (their height, age etc).  Over the last 150 years, they have ben subject to the pressures of commercial logging, clear felling and more recently high intensity fires.  Indeed, the fires have been of such an intensity that seed banks in the soil have been destroyed. Now they have been subject to genomic analysis, that is their DNA has been analysed and sequenced.  The first conifer genome to be sequenced was that of Norway Spruce, then that of loblolly pine.  These suggested that conifer genomes are large (3 to 10 times larger than the human genome), with repetitive sequences.  Coast Redwoods are hexaploid, that is, they ave six copies of each chromosome (we are diploid, that is, have only two copies of each chromosome).   The DNA of a coast redwood has  27 billion base pairs of DNA, the giant sequoia has 8 billion; by contrast we have circa 3 billion.   It is hoped that the Redwood Genome project will see the restoration of areas of coast redwood and giant sequoia that have been lost over the years. The genomic analysis will help inform and guide management strategies, ensuring genetic diversity in the newly planted tree seedlings. Such a strategy will (hopefully) enable newly planted areas to survive and thrive — in the Anthropocene. More on chromosomes Just as it has recently been shown that Coast redwoods are polyploids (i.e. have extra sets of chromosomes), so recent research in the Czech Republic has shown that the common nettle [Urtica dioica] has different ecological ‘preferences’ depending on its chromosomal status.  Nettles can be diploid (2n = 26) or tetraploid (2n = 52).  The tetraploid nettles seemingly have a broader ecological tolerance and a wide geographical distribution, whilst the diploid nettles occur in a narrower range of ecological conditions. Details of this research can be accessed here (note link opens a PDF) and Plants for a future has lots of information on nettles.    

When I say I get a buzz out of detecting I mean it literally: a good detector device makes a different buzzing sound for different metals.  A low note or deep buzz means it's probably iron and not worth digging up, saving the detectorist wasting time digging out old nails or fence wire.  In contrast, a higher/lighter tone means you are more likely to be finding bronze or even maybe the detectorist's dream - gold or silver coins. Today I did my first day of metal detecting with an expert detectorist, Joe Green, part of the "dynamic trio" as he and his team call themselves.  Joe took me around a woodland where he has permission to detect and we spent three hours scanning the ground and digging out finds.  In that short time we found: two old bullet cases as the wood had been used for army training in WW2 one bullet one musket ball probably dating from around 1800 CE, might be earlier two Georgian buttons one thrupenny bit / threepence, from the 1930's a buckle a worn Georgian halfpenny Less usefully we found one ring-pull, some foil, and about half a dozen discarded shot cartridges from pheasant shooting in recent years.  All the items we found were within six inches (15cm) of the surface and in good flinty/chalky soil they will usually be even nearer to the surface.  Clay soils are more difficult and objects often escape detection by sinking down over the years. According to Joe, my guide and mentor, it's a logical but probabilistic game where you look for features and ancient tracks and if you detect something interesting you should concentrate on that area as finds are often concentrated into "hot spots".  High ground is often promising and sites of ancient settlements can be rewarding.  Joe has been really successful and has found some gold and silver coins some of which are currently at the British Museum which may be bought from him.  As any detectorist will tell you, there is always a moment of optimistic anticipation between the moment when the metal detector bleeps and when you have excavated and brushed off your find.  After the tell-tale bleep it's not always quick to track down small finds and many detectorists use a small handheld device for the last bit of close-range finding, called a "metal detector pinpointer". Joe showed me how to use the detector so that the head of the device, the coil, was parallel to the ground and I swept the head in wide, overlapping arcs so that no stone is left unturned - if it's got a coin under it.  Some of these devices have larger coils which enable more area to be covered and give the coil a better reach.  For our detection we used a Deus 1 detector, costing about £750 but Joe is about to invest £1,400 to get the Deus 2. "The UK is remarkably liberal for detectorists and although you need the landowner's permission you don't have to be qualified to detect', says Joe. In France,  a detectorist needs a special license from Authorities to search an area of land, as well as permission from the landowner. In Poland, detecting is banned.   Joe adds that "you can't detect on Sites of Scientific interest, Ministry of Defence land or Historic Monuments.   Also, if you find "treasure", such as gold or silver over 300 years old - you have, in England and Wales, to give first refusal to the authorities in case they want to buy it from you for a museum.   Usually if they do buy you find, the proceeds are shared equally between the landowner and the detectorist". For my metal detecting outing I had done some armchair homework by watching Mackenzie Crook's BBC Four series called "Detectorists".  It's a magical introduction to metal detecting, the club rivalries, nighthawks (illegal night-time detectorists), and the use of detectors to find lost objects.  It also has some scenes where Toby Jones portrays a character who finds gold "treasure" which gets displayed at the British Museum. Joe has a real ear - and eye - for the metal detecting hobby and he's been doing it for 13 years.  On our outing he found a shiny city livery button which he has dated to 1825 and was bought from a London Taylor's shop.  Livery buttons were part of the uniform that was worn by servants to a particular estate / household.  May be it was lost whilst searching the area for firewood. My half day of detecting left me astonished to find just how much metal there is in an ancient woodland.   It made me realise just how much unrecorded history exists in every part of Britain and how much of life used to happen outdoors.  In our three hour session, we must have detected about 20 interesting objects over just a very small part of the woodland - in the whole wood there must be hundreds, perhaps thousands, of hidden objects.  History may be unrecorded here but it has left traces and detectorists have an important role in exposing the past life of woodlands. Treasure may be 2 or more silver or gold coins found together that are more than 300 years old, or if they contain less than 10% gold or silver there must be at least 10 in the find for it to qualify Any object that is more than 300 years old that contains more than 10% precious metal 2 or more artifacts which are base metal (not gold or silver) that are found together.
