False Friends

Fungus observations from LAPLAND


My fungus misidentification skills have been abroad! To Lapland the land of the Sámi and the vast, wild expanse of the taiga: the boreal forest that stretches across Norway, Sweden and Finland to Russia, and beyond.

First stop was Muddus national park in Sweden, a huge area of old growth forest, lakes and marshes which has been protected from the effects of commercial forestry – first by the glacial landforms which made the area upstream of Muddus's spectacular waterfalls and canyons unsuitable for logging, and later by the work of conservationists who secured national park status for the area in 1942.

Muddus national park, Sweden. A place so magical the waterfalls look like wizards.

Arriving in Muddus at the end of May, after the snow and before the mosquitos, we were greeted by temperatures over 25 degrees. Being situated in the arctic circle, around 66 ° North, the sun never really sets at this time of year – so the hot days were followed by balmy evenings which seemed to go on forever.

Many habitats are marvellous in Spring, but I have never before experienced one quite so enchanting. Happily, the park is crossed by well-maintained paths and boardwalks, so there was no cause to worry about any Babes in the Wood -type scenarios.

My first fungal encounter was with this toadstool, growing by the path. Observing its distinctive wrinkly cap and paler stem, I announced confidently:

"This is a Morel! They're a delicacy in France."

Toadstool in Muddus national park, Sweden

As the days of hiking through the taiga wore on, I noticed that these toadstools occurred regularly along the sandy, drier sections of the path. They began to seem familiar. I wondered what they would taste like fried in butter.

Fortunately I know better than to trust my mycological knowledge. As soon as we were back in the land of people and mobile phone reception, I turned to the internet for information which might confirm my identification...

These were not Morels! They were False Morels (a Gyromitra species) – DEADLY POISONOUS!!!

I hesitate to put a species name to them as there are probably more Gyromitra species in Scandinavia than are known to me, with my British field guides. But the habitat and 'jizz' match closely with descriptions of False Morel Gyromitra esculenta, said to be "very poisonous".
 
Imagine then my confusion upon seeing this now familiar fungus lining the shelves in Kiruna supermarket, on tins labelled "Murklor". A quick rummage around in Wikipedia (assisted by the awesome power of Google Translate) suggests that "Murklor" is a collective term for Morels and Morel-like species. However, the list of 'ingredienser' has Gyromitra esculenta my poisonous friend as the chief ingredient.

Further trawling through Wikipedia has revealed that, although potentially fatal if eaten raw, Gyromitra esculenta is a popular delicacy; in Scandinavia, not France as I had originally proclaimed. But they must be prepared carefully to reduce their toxicity and, even then, food safety experts seem divided over whether they are actually safe to eat.

I'll stick to just enjoying how they look.

May the fungus be with you


I'll admit it, I thought fungus was over for the summer.

I should have known better: FUNGUS IS NEVER OVER! It's just waiting for a good day to get fruity.

That's what I've learned this month, after stumbling across these beautiful fruiting bodies basking in the sunny Sussex countryside.

Big, brown and round
Burgeoning from a fallen Ash bough, we spotted this fresh polypore next to a footpath just outside the village of Sutton (near Bignor) while on a butterfly walk with Sussex Butterfly Conservation. We'd done a recce of the route the week before and not seen them, so I reckon these must have sprung up during the first week of May.


Thanks to Cat Åkesson for offering me her hand, for scale you can see that the biggest of these fruiting bodies were almost the size of dinner plates.

Just about visible in the photograph below, the round brackets are growing from a robust stem (strictly speaking, a 'stipe') and the creamy white underside is a mass of slighty irregular pores.

After consulting with my growing collection of field guides, I am inclined to call this Dryad's Saddle Polyporus squamosus a common and widespread species which fruits in Spring or Summer. The Collins (illustrated) Fungi Guide describes it as "a large and unmistakably beautiful fungus." So here's hoping I'm not mistaken.

Peaches and cream
Wow! What a find! On a lunchtime stroll around Woods Mill, Roger French caught sight of this voluptuous beauty growing on the end of a big old log (not sure what species something deciduous).

The colours are just sensational vibrant shades of peach and apricot. And the surface is delightfully smooth.

A couple of people in our group (not me) recognised it immediately as Chicken of the Woods Laetiporus sulphureus. It's another common and widespread species which fruits in Spring to Autumn.

Personally I think it deserves a prettier name. Like 'Apricot Dream', or something.

Something in the flowerbed

Something caught my eye as I walked up the garden path this evening. Something in this flowerbed:

In preparation for planting a row of young Blackthorn whips here last winter, we'd dug a barrow-load of peat-free compost into this bed. And, following a few heavy April showers, it seems this compost is providing some prime habitat for another species...

This cup fungus has sprung up all along the length of the bed:

The fruiting bodies vary in size from about one to five centimetres across and all share this rounded shape, with a narrow opening at the top. The upper surface, around the opening, is ever-so-slightly pimply-looking; like it's got little brown goosebumps. When you break it open, the inner surface is the same colour as the outer surface, but forms a separate layer with a slightly smoother texture.

It doesn't have much of a stem to speak of.


Having consulted with the Collins Complete (photographic) Guide and the Collins (illustrated) Fungi Guide, I'm going to take a punt on this being Blistered Cup Peziza vesiculosa:


"Distinguished by its clustered, blister-like growth. Fruits year-round. FRUIT BODY To 8cm across; initially deep cup- or goldfish bowl-shaped with a strongly inrolled margin, but expanding to saucer-shaped with the margin splitting and becoming ragged or blistered; inner surface yellowish brown with a smooth texture; outer surface similar in colour and finely granular. HABITAT Typically in tight, fused clusters on straw, manure, compost and rich soil, and increasingly on woodchip mulch. STATUS Widespread and common."

Bog Beacon

Small stream that runs along the southern edge of the plateau at Park Corner Heath, looking east towards the pond.
It's fairly common knowledge among the volunteers involved in managing Butterfly Conservation's Park Corner Heath and Rowland Wood reserves, near Lewes, that one of the visual treats you can look forward to here, as Winter turns to Spring, is the fruiting of the Bog Beacon Mitrula paludosa.

As the Brimstone butterfly emerges from hibernation to patrol the woodland rides, looking for a mate, the Bog Beacon arises also, in the dampest places, to put on its own reproductive display. We saw crowds of them this morning along the stream which borders the southern edge of the plateau at Park Corner Heath (pictured above).

Over the years Butterfly Conservation volunteers have put in several small dams to slow the flow along this stream and create a series of small pools. The work was done primarily to improve the habitat for dragonflies and damselflies, but seems to have also created ideal conditions for Bog Beacon.
Bog Beacon habitat
Bog Beacon doing whatever it is that Bog Beacon does.
Over in Rowland Wood there's another site where the Bog Beacon reliably appears a particularly wet ride which runs between the lake and the Big Beech.

Wet woodland ride in Rowland Wood, where Bog Beacon occurs.
And here's a little gang from that Rowland Wood population, up close:


Being new to recording fungi, I tend to assume that if *I've* managed to find and identify a species, it's probably something fairly common. So I was surprised to discover that, while this species does feature in the Collins Complete (photographic) Guide, it doesn't get the slightest mention in the Collins (illustrated) Fungi Guide – although the latter does include a selection of "the more common, conspicuous, large, interesting and/or distinctive" ascomycetes.

Well, this looks pretty conspicuous, large and interesting to me so perhaps it's been left out because it's not very common?

I looked on the British Mycological Society's FRDBI database online and it includes only two records of M. paludosa from East Sussex: One from Vert Wood (part of the same woodland complex as Park Corner Heath & Rowland Wood) in 1967; and one from Chelwood Gate in 1979. But the species must be more widespread than the FRDBI records suggest because Googling "Bog Beacon Sussex" brings up a bunch of other records and photographs of this charismatic species.

Worth sticking the record in then!

Counters Gate

After picking up my new fungi books last Saturday, we drove over to Counters Gate near Goodwood for a walk up through the woods of Eastdean Park / Charlton Park heading in the direction of East Dean.
Looking east from the public footpath, into Eastdean Park.


Walking through the coppice woodland (SU8911) the first fungus I came across, growing on hazel, was this:
Not a very good photo, but it's a pale, thin bracket fungus velvety on top with pores on the underside. In a radical break with tradition, I'm not going to say, "Yeah, I think it's Turkeytail." My guess is this is different Trametes species – either T. hirsuta or T. pubescens (if only I knew how to tell the difference).

I'm in a similar fix with this next one. It's the same sort of colour as the previous fungus but has a flatter and smoother fruiting body, and is considerably less hairy. Perhaps this is T. pubescens and the one above is T. hirsuta. They're similar species apparently, but T. pubescens is more "finely silky or velvety".

And then a few I think I can do...
Birch Polypore Piptoporus betulinus
King Alfred's Cakes Daldinia concentrica
Glue Crust Hymenochaete corrugata
The next one puzzled me for a moment, because it was growing in this ear-like form, similar to Jelly Ear Auricularia auricula-judae, but almost black. I think it's actually another example of Witches' Butter Exidia glandulosa; the Collins (illustrated) Fungi Guide says the fruit body is "initially cup- or ear-like" and then grows into the distorted forms I've seen before.

The path eventually comes out into a clearing surrounded by mixed woodland of Beech and Oak (SU8912).

This great windblown Beech looked to be providing some excellent fungi habitat...

... including for this bracket fungus. I reckon this is a Ganoderma but there are several that look alike and are much confused: Artist's Bracket G. applanatum and Southern Bracket G. australe being the two which are most commonly found on Beech. There's also the Beeswax Bracket G. pfeifferi which apparently has a resinous or waxy surface that can be "melted with a lighted match". So, something else I should be carrying around in my bag of fungi-hunting apparatus – a box of matches.

I got quite excited about finding this rich brown crust fungus, growing on Oak, as I think it's another new species for me: Oak Curtain Crust Hymenochaete rubiginosa.
 

It was growing above head height and the light was low, so another terrible photo...


... but you can see it's growing tightly against the wood where the bark has come off and forming tiers of overlapping brackets, which is right for H. rubiginosa. The book says you should be able to see "fine bristly hairs" on the upper surface, with a hand lens, but I can't.

I also saw lots of this going on another crust fungus the colour of my spare room. I was hypothesising the other week that this might be a Peniophora species. But I've got a new theory this week. The Collins Complete (photographic) Guide says that Glue Crust Hymenochaete corrugata can look similar to resupinate species of Peniophora, so maybe it's that.

Gonna need another bigger book for all these resupinate characters! As well as some microscopy skillz.

Funga Nordica

Funga Nordica
A few weeks back, after I'd spent much of an afternoon struggling to identify a mushroom I found at Park Corner Heath (which I eventually concluded *might* be a Psathyrella species), I asked Martin Allison, the Sussex County Recorder for Fungi, how one goes about putting a name to a species such as this:

"You're going to need a bigger book," Martin replied. And the book he recommended was Funga Nordica. (Actually, Martin's advice was more along the lines of: You're going to need a lot of bigger books, and most of them are very expensive, but the place to start, if you want to get into serious mycology, would be Funga Nordica.)

Imagine then my disappointment upon discovering that Funga Nordica is out of print, sold out everywhere, and IMPOSSIBLE to get hold of.

Some weeks later, I received an email from another Sussex mycologist, Howard Matcham, who said he's been enjoying reading this fungi blog and, as he is focussed on studying other, even-more-obscure, forms of life these days, asked if I would like to have his copy of Funga Nordica – to give me "a nice start in my mycological career".

WHAT LUCK!

Of course I replied, "YES PLEASE!".

And that wasn't it: Howard also had a copy of Collins Fungi Guide he was offering to give me – the illustrated one. This too had been on my wishlist ever since it was recommended to me by Graeme Lyons, as I gather it includes more comprehensive coverage of all the UK species than my other field guides.

My cup runneth over! And my bookshelves are runneth-ing over too, so I've had a bit of a re-organise. Here is my new "Mycology" section:

Trip down Marley Lane

To Haslemere today for lunch and, amazingly, after a particularly delicious plate of roast lamb and a glass of beaujolais (pronounced "bow - joll - iss" by Dad, because he has a reputation to maintain), I managed to convince my dear parents that they would REALLY like to spend Mother's Day afternoon wandering around Marley Common, looking at bits of dead wood.

Yes, Reader, I hail from Over The Border: Haslemere. Nestled up against Surrey's boundary with Sussex and Hampshire, people from Haslemere reach parts of Sussex that the Sussex-dwelling folk don't tend to get to very often. And so it was today: We headed south, out of Haslemere, to Marley Common. To Sussex! And the site of one of my earliest fungus forays.

In truth I never went 'up Marley' very often when I was growing up in Haslemere. Because, for a walk, it's just not quite as good as Black Down. But apparently it is rather good for fungi; so I've got a feeling I'll be spending a lot more time here in future...

We saw various aged bracket fungi which I moved swiftly past because I still have no idea what I'm doing with bracket fungi (other than saying, "yeah, I think it's Turkeytail," repeatedly, upon encountering almost every bracket fungus I see).

I attempted to impress Mum by showing her what-I-think-was Peniophora quercina, but she just thought it looked like a bit of dead bark. And I'm not sure excitedly pointing out that it was "SLIGHTLY CRAZED!" really convinced her of its fungal nature.

She was fairly impressed with these though. More tiny red beads!
 I'm going to go out on a limb here and say these may be the anamorph of another Nectria-like species – like what I found (and misidentified) in Hoe Wood the other week. It was growing on one of the upright branches of this fallen (birch?) tree:

Nick Aplin (Sussex Fungus Group) has said he'd be interested to receive collections like this from Sussex, so looks like I'll be down the Post Office again tomorrow.
