Fungi Friday 23rd October 2020

I want to start by saying thank you to everyone who stopped by last week to read my click-bait post about honey fungus. The post had nearly 200 views in one day, which is a huge amount for this blog and broke the single day record. My blog could have nearly twice the number of visitors as in 2019, probably due to the fact I have had more time to walk locally taking photos and to spend time writing these posts. Otherwise I would be stuck in a car driving to and from an office I probably didn’t even need to visit so often.

I think the fact more people are working from home could be key to protecting local green spaces going forward. In the UK ‘lockdown’, as the period of late-March and most of April and May 2020 are known, millions of people discovered their local green spaces. If people value something close to home, they will learn about it and in their stewardship, nurture and defend it. I discovered fungi close to home, and I’ve sought it closer and closer ever since.

This week I visited a nearby area of oak and beech woodland in the High Weald of Sussex. I’ll admit it now, I was disappointed. This time last year I encountered many more species than I could find this year. I think fungi in Sussex are paying the price for a very dry spring and summer period. I did warn you. That said, I did find some small things that were happy to pose for a photo. Above is sulphur tuft, one of the most common species you can find.

This is black bulgar, a rather odd species that seems to explode in October on large fallen branches. The first time I saw this, it had appeared on the fallen limb of a massive oak tree which had come down that summer.

This rather unsightly mushroom did get my heart racing at first. I thought it was perhaps my first local deathcap, but really I think it’s the false deathcap. It has the classic Amanita bulb at the base. I think the colouring of the cap is wrong for deathcap and it has some of the brownish scales of the false deathcap, on the cap.

When the ground isn’t producing the shrooms needed at this time of year, I look to the moss growing on tree trunks. You can often find very small mushrooms there, perhaps bonnets (mycena) or galerinas. The moss holds on to the rainfall for longer, meaning fungi, some of which are parasitic on moss, can prosper. Let’s call them… mosshrooms!

This lovely little mosshroom had actually snapped but I rotated the image for effect.

This beautiful little grey-blue mushroom epitomises the mossy shroomlet. As you can see from the moss fronds, it was very small indeed.

One of my first #FungiFriday blogs was about candlesnuff fungus. It looks quite neat at the stage seen above, when it is first beginning to fruit. In dry conditions you can flick the white ‘wick’ and the spores appear as smoke from a snuffed candle.

A similar type of fungus was this yellow staghorn, a common species. It was growing down on a mossed-over stump on the woodland floor. That oak leaf on the right (I think Turkey oak, Quercus cerris) is so beautiful.

The most unusual find was in the raised rootplate of a rhododendron. From above they looked like potatoes. I am fairly confident this is a cep, Boletus edulis. It is, of course, also known as porcini and is one of the most sought after edible mushrooms. Foraging is not something I do commonly, so I left it there to grow on its merry way.

This scraggly crew are a common but no less beautiful mushroom – amethyst deceiver. They are easy to identify due to their colour and size and are a very common species in the UK. I do find that they are happier in older, more stable woodland. Aren’t we all?

Thanks for reading.

Cairngorms - September 2018 djg-34

Fungi Friday 1st May 2020

For another week the Covid-19 pandemic is keeping me away from the woods and therefore the shrooms. This fungal breaking news desk has run out of scoops, so it’s more like a sports channel airing classic re-runs.

I had been intending to post about some fantastic fungal hiking experiences (sounds weird) from a 2018 visit to Scotland but work and life stopped me. I do hope anyone reading this is doing well and that you’re following the guidance.

Cairngorms - September 2018 djg-4

These posts remind me of my uncle Joe Reilly who passed away in November. Joe was a Glaswegian by birth who, along with my aunt Marg, introduced me to some of the most beautiful places the UK has to offer in Perthshire, among so many other gifts. I would visit Marg and Joe in Perthshire as often as I could, often in autumn when going to meet my hiking companion Eddie (seen here) for a jaunt in the Cairngorms.

Joe fell for fungi like I did in recent years and I will always miss his WhatsApp messages with mushrooms he had found on Perthshire walks. We miss his thirst for life terribly but carry it on just as he did.

Last week I was sharing fungi found on a hike to the top of Ben Vrackie in Perthshire.

This week my final Scotland post makes me feel like a bit of a cheat. The post is built around an incredible hike led by the rangers of the Balmoral Estate in the Cairngorms National Park with only one serious mushroom to be found. But it was one special shroom, and probably one you want to eat if you haven’t already. I will soften that blow with some dodgy phone pic shrooms.

I was visiting the Cairngorms for a Europarc Conference and there was very little time to get out on foot in the mountains and hills. Most of my photos looked like this one above, a phone pic taken while being ferried around in a minibus.

IMG_20180918_120728899_HDR

I was staying in Aviemore and there were a pleasing selection of shrooms found right next to the pavement in the verges. This is a giant puffball in its early stages, part brain part, well, bottom.

IMG_20180918_121133071_HDR

I’m not entirely sure what this species is, I thought it might be in the Macrolepiota/Lepiota family (where parasols are found) but can’t find a candidate just now.

IMG_20180919_180948746_HDR

This is almost certainly brown rollrim, a deadly poisonous fungus. It’s growing out of ballast, which is no surprise as I’ve seen it growing next to pavements in south London.

IMG_20180918_121355902

And behold, a very well trampled cauliflower fungus.

IMG_20180918_190309993

Winner of the truly worst phone pic was this fly agaric which was absolutely belting it out from underneath a hedge in a residential area.

Cairngorms - September 2018 djg-17

As mentioned at the start of this blog, I was lucky enough to go on a hike to Lochnagar on the Balmoral Estate, led by a very nice ranger and a professional guide, who was also very nice. There were National Park staff from all across Europe. I spoke to one ranger from Iceland who would be spending her winter driving around the vast areas of her Park undertaking works to signage and all manner of other things. She was the real deal. Our National Parks are tiny in comparison to many in Europe, though the Cairngorms is the closest we probably get to some of Europe’s most rugged wildness. The Balmoral Estate is not a good example of that because of the intensive management to support grouse shooting. Apparently the Queen still drives around the Estate in her Land Rover.

Cairngorms - September 2018 djg-18

There were extreme winds at the time of the walk and we didn’t make it to the peak of Lochnagar. It was too dangerous. Though you’re unlikely to find much fungal diversity at these altitudes (1000m+) there was a familiar neon lichen on the boulders. This is Rhizocarpon geographicum.

Cairngorms - September 2018 djg-26

It took a real effort to actually hold my camera in place and take this photo. It was incredibly windy. This is Lochnagar. The peak can be seen in about the middle distance where a small cairn stands.

Cairngorms - September 2018 djg-32

At this point we were all told to put our cameras away because the winds were going to hit hard. They did, it was incredible.

Cairngorms - September 2018 djg-1

You’re probably wondering – where are the shrooms? But let it be a lesson to you, finding fungi can be really hard. Sometimes it’s all there at the side of the pavement, but at other times you will see nothing.

Cairngorms - September 2018 djg-3

At the point where our minibus was parked I could not believe what I saw. This is a cep, otherwise known as porcini or pennybun. Its Latin name is Boletus edulis. It is the most prized edible mushroom. This was the most perfect specimen I have ever come across. In the background is Loch Muick, with the classic Scottish rain, sun and wind falling in the background. I can still get a tingle of the joy of finding this mushroom, against that background, in such a stunning location.

Thanks for reading.

Autumn 2015 in southern England began with a prolonged dry period reminiscent of 2011. This meant that a lot of fungus was late to fruit. Other than a September burst of honey fungus, there was little to see until the rain came and enriched the thirsty mycelia of British woods and meadows. Here is my year in mushrooms:

Fungi 2015 blog pics-4

Oyster mushrooms, Pleurotus ostreatus

One of my favourite things to photograph is mushrooms, yet the act of closing the shutter is often only a small part of the experience. I can go looking for mushrooms and sometimes come away with very few photos. I have to walk until I find something, heading to the right place at the right time of year to find it. I know plenty of fungi enthusiasts who pick and cut mushrooms to identify them, a key process in understanding a species. As a photographer I see no reason for me to pick them. I’m much happier leaving the specimen where it is so someone else can come along and enjoy it, as short-lived as many fruiting bodies are. If it’s a fungal foray to raise awareness and celebrate mushrooms, picking them is great.

Bonnet mushrooms, Mycena on a dead oak tree

September to November is the right time to head out looking for the larger spreads of mushrooms, though they can be found all year round. I find enormous pleasure in that early autumn period when the moisture levels are right (fungal fruiting bodies are 90% water) and fungus abounds from every fallen tree, even the most barren of parkland funked out by funnels, inkcaps and fairy-rings.

Fungi 2015 blog pics-5

One of the most sought-after edible mushrooms is the cep, Boletus edulis

I found a cep, Boletus edulis under a rhododendron bush in the New Forest in October. It didn’t quite match the images of bountiful porcinis (the Italian name for the cep, also known as the penny bun) but I still had no desire to take it home with me. Fungi engages people like very few wild plants or animals can, mainly because they are renowned for their edibility and their poison. From my understanding, mushroom picking is not as popular in England as it is in Poland, Estonia, the Czech Republic, France or Italy. Indeed, perhaps it is the Mediterranean influence over British culinary culture that has seen mushrooms become such a hot topic in debates about sustainable foraging. In Britain we lack the vast wooded landscapes of Transylvania, of the Tatras, Dolomites or Pyrenees. Perhaps our landscape is mycologically impoverished.

An inkcap, Coprinus or brittlestem, Psathyrella, I wasn’t quite sure

One thing that always interests me is a land manager’s attitude to foraging mushrooms. The City of London own many excellent nature reserves on the outskirts of the city and they have a no picking policy. Likewise many urban nature reserves discourage visitors from picking mushrooms. The Forestry Commission have a mushroom code, allowing only a certain weight of mushrooms to be picked and the clear message that only mature fruiting bodies should be plucked. It depends what your interest is, but as an observer I err on the side that fungi has an important role to play in an ecosystem and should largely be left alone, especially in urban nature reserves. At the same time I appreciate that it’s unproven that collecting mushrooms has any meaningful impact on the mycelium itself. As a conservationist, I tend to support the land manager’s picking only with permission, as difficult to enforce as it may be.

A fly you’ll often find on the cap of a mushroom

Fungi has a massive role in the health of woods. Species like beech, birch and oak have a strong dependency on fungi to provide them with nutrients and minerals that are otherwise impossible to retrieve from the soil. The mycelium of a fungus which fruits from the soil lives underground. The mycelium is made up of hyphae which extend through the soil, feeding on decomposing matter. The hyphae sheath the root hairs of a tree and a trade takes place between tree and fungus, a symbiotic relationship. The tree can delegate where the hyphae should extend in search of nutrients. The hyphae can then pass the nutrients into the tree via the root hairs. Water is often passed in return to the hyphae to nourish the mycelium and make the production of fruiting bodies (mushrooms) all the more possible. Experiments have been done to show that these mychorrizal relationships boost the growth of trees greatly. This is why the idea to dig up trees and replant them elsewhere to protect ancient woods is impossible. The soil is crucial. Trees are not everything.

A cup fungus

Fungi has made me think very carefully about the camera equipment I use. The diversity of species means that there are an array of lenses and cameras you can use. There is no perfect set up. I use a Sigma 105mm f2.8 macro lens to capture the smallest of mushrooms. Lying on my stomach in the New Forest revealed many incredible things hidden away that I would otherwise not have noticed. A macro lens, though often a costly investment, can open up a new appreciation for nature.

A tiny species of bonnet, Mycena

Some of my favourite species to photograph are bonnets (Mycena) and parachutes (Mirasmius). They are so incredibly tiny but so common, simply searching for them is an adventure. Again, the best place for these is woods with a thick layer of leaf litter, but they can also be found on mossy logs, and even on the end of sticks.

Fungi 2015 blog pics-5-2

Twig parachute, Mirasmiellus ramealis

At the RSPB’s Blean Woods in Kent I crouched for many minutes, fearful of dogs weeing on me, to photograph this twig parachute. It measured barely a few millimetres across. I found it because I knew where to look. My knees ache still.

Fungi 2015 blog pics-2-3

Orange peel fungus, Aleuria aurantia

Not all fungi is especially beautiful or in beautiful places. Many mushrooms are in poor condition because their time in the limelight is very short and they are affected directly by weather and other environmental factors. Slugs eat them, flies mate on them, people step on them. I found this orange peel fungus (Aleuria aurantia) on an embankment near Oxted, Kent outside a haulage company depot. The bank had been denuded of trees, their stumps poisoned. But the thing about nature is that it doesn’t care about how crap a place looks if the opportunity for propagation exists. This fungus looked more like some plastic debris half submerged in the ground.

Lycogola terrestre

Also not all of the beautiful fungus you find is actually fungus. One spot I return to each year, a dank log pile next to a path in some dark beech woodland, is lit up by Lycogola terrestre. This is no fungus but instead a slime mould. This is an extreme close up of one of the fruiting bodies which appears on a bed of moss in a very small area.

Camberwell Old Cem blog pic-1

Shaggy inkcaps, Coprinus comatus growing next to new burial plots

Another of fungi’s pleasures is an ability to surprise. Millions of spores are released by a single mushroom (30,000 million an hour by a mature bracket fungus) and so it is unsurprising to find mushrooms growing in the streets. At Camberwell Old Cemetery in south-London, four-year-old burial space has been a successful breeding ground for shaggy inkcap (Coprinus comatus). I used a 300mm telephoto lens to photograph the scene above. Seeing as the graves were newly-laid I didn’t want to intrude.

The wreckage of waxcaps blog pics-3

Honey waxcap, Hygrocybe reidii

The best grasslands to find fungi are either ancient grasslands like Farthing Downs where I photographed this honey waxcap, or church yards. Waxcaps (Hygrocybe) are a strong indicator of the age of grassland. There are over 1000 species in the UK, their burst of colour in the winter doldrums add life to otherwise dormant meadows. The mild winter this year meant that waxcaps were fruiting alongside field scabious, knapweed and even yellow rattle on Farthing Downs.

Coral fungus growing in the lawn of a Dorset church yard

In church yards the lack of grazing pressure and the ‘respectful’ management of the turf means that there are likely to be well established mycelia under the graveyard lawns. These are excellent hunting grounds for corals, Ramaria. The problem is they’re often so small it can be difficult to get a good image from a cumbersome DSLR. Instead I use my camera phone to try and get a closer look. It has a fancy in-built lens and can manual focus as if turning the focus ring of a DSLR lens by using the screen. The results were very pleasing.

An ancient pollard oak on Ashtead Common

The best places to find fungi are woods and meadows, generally those that are either ancient or relatively well established nature reserves which are sensitively managed. One of the new places I visited was Ashtead Common in Surrey. Ashtead Common is a Site of Special Scientific Interest (SSSI) and National Nature Reserve (NNR), mainly designated for its ancient pollard oaks. This collection of old trees means the diversity of fungal and invertebrate life is very high. The City of London manage their reserves very well indeed and Ashtead Common proved to be one of the best early sites to visit.

The rich leaf litter in Blean Woods

RSPB’s Blean Woods NNR is a wonderful place for wildlife in general, not merely fungi. It is a vast network of woods that flank the city of Canterbury adding a level of sylvan mystery. Blean Woods is broken up into different habitats, with spots of heathland, birch and sweet chestnut coppice which provide vital nesting opportunities for nightingales and enough light when cut to support common cow wheat, the food plant of the endangered heath fritillary butterfly. In October the woodland floor was covered by a sea of black mushrooms that, I discovered later, were horn of plenty (Craterellus cornucopioides).

New Forest blog pic-1

Roydon Woods

It’s hard to say there is a best place to find mushrooms due to the transient way the fruiting bodies appear. My favourite place has to be the New Forest in Hampshire. The above image is of the Wildlife Trusts’ Roydon Woods NNR, an ancient broadleaved wood very close to Brockenhurst. The New Forest was probably like Ashtead Common in centuries past, with a structure more reminiscent of wood pasture (or savannah) where the trees were less close together and the grasslands were sunnier and luxurious. Roydon Woods has the feel of a landscape that is untouched by people, though such a thing does not exist today. It is possible to spend a day there and meet very few visitors but all manner of mushrooms.
