Mushrooms, thousands of 'em


Entering Hoe Wood, I noticed a small cluster of mushrooms nestled between the roots of an oak tree up ahead.


As I walked further on I realised, these same mushrooms were... everywhere.






Tight clusters of them pressed up against the oak trees.





In fact most of the oak trees in the wood had mushrooms for company.


I think these are Spindle Toughshank Collybia (Gymnopus) fusipes, a common mushroom which grows at the base of deciduous trees, especially oak.

They grow in tightly fused clusters and the stipe tapers down to the root base. Like a spindle (if anyone knew what a spindle looks like any more).


The Collins (illustrated) Fungi Guide describes the gills as "crowded", while the Collins Complete (photographic) Guide describes them as "very distant". So that's not very helpful. Both books say the gills are rather irregular.


Well, I'd say these are rather irregular. And more distant than crowded.


The time of year is right for Spindle Toughshank Collybia (Gymnopus) fusipes too.

Some like it hot

Thought I'd nip across to Hoe Wood at lunchtime, see what's happening.

Spotted this on the way there a bracket fungus growing on a fallen bough of a big old willow tree.




Wasn't sure what it was at first, but the Collins Complete (photographic) Guide has a handy section at the back highlighting species to look out for in particular habitats. Blushing Bracket Daedaleopsis confragosa is one of the species it says to look out for on willows.

I have seen Blushing Bracket before in almost exactly the same spot, but only in its old age when the brackets turn a deep beetroot colour.

These young Blushing Brackets are all shades of white and beige. You have to give them a squeeze to make them blush, and then the underside turns a deep reddish brown.

My thumb print.

I think these must be very fresh. When I brushed away a fallen leaf from the surface, I noticed the fungal tissue had grown up beneath it, creating a perfect impression.


It will be interesting to see how long they stay this white.

Despite lingering a while by these Blushing Brackets, I did make it as far as Hoe Wood today where I was surprised to find yet more things were happening in the fungal kingdom, in the dry heat of August.

Unfortunately my camera battery didn't make it that far. So that story might have to wait until tomorrow, and another lunch break.

Smooth and elegant

I fancied a stroll after work this evening and headed north out of Small Dole towards Oreham Common. At the edge of the public footpath, as I approached Oreham Manor, I happened to catch a glimpse of these.


Sprouting from a well-rotted log, beneath some scrubby trees and surrounded by lanky-looking light-starved nettles, was a colony of... well... what?

I imagined they'd be some kind of oyster mushroom. But a quick up-stipe shot revealed... no gills!


By now I was flicking frantically through the pages of my Collins Complete (photographic) Guide, looking for mushrooms with (a) no gills, and (b) no visible pores. No joy.

At this point I decided to phone Michael, who has been very supportive of my fungi-finding exploits, and ask if he would come and meet me, bringing a copy of the Collins (illustrated)  Fungi Guide, which I'd earlier decided was too heavy to put in my rucksack.

Perusal of the Collins (illustrated) Fungi Guide convinced me I must be somewhere in the genus Polyporus – stemmed polypores with a "toadstool-like fruit body; often with excentric or lateral stem; on wood". But I couldn't match what I was looking at to any of the species described in the book, so I took a small specimen for closer examination at home.

Here it is:



What to say about it?

The elegant outline is perhaps its most striking feature making stipe and cap one seamless sweeping structure,  finished off with a thin and perfectly-rolled rim.

The underside of the cap is an attractive chalky-white colour, with a gradual transition through shades of mousy-brown to the base of the stipe.


The mouse-brown cap has a slightly waxy finish and the underside appears perfectly smooth. Even with a hand lens, I can't make out any pores.

And it has a pleasant mushroomy smell.

The closest match I can find in the Collins (illustrated)  Fungi Guide is the Fringed Polypore Polyporus ciliatus, which fruits in Spring to late Summer widespread but uncommon. (This species isn't included in the Collins 'Complete' (photographic) Guide.)

But I read somewhere else that Polyporus ciliatus is so called because it has fine bristly hairs on the cap and margin. Even looking down the microscope, I can't see any hairs. The rim just looks, well, smooth.


Might share this one on the Sussex Fungus Group forum and see what they think.

Summer Fungi

With a heatwave around the corner, I was keen to get out and find some fungi this weekend before everything gets frazzled.

I decided to head for Horton Wood, a small corner of ancient semi-natural woodland near Small Dole.

Nestled amongst the dry leaf litter, I found these earthballs.


There are a few species of earthball which all look quite similar. I'm hazarding a guess that this is the Common Earthball Scleroderma citrinum as, according to the Collins (illustrated) Fungi Guide, this species is "attached at base to substrate with coarse whitish mycelial strands." I think I can see these strands in these in the photograph below. Although, at 3 cm diameter, it is a little on the small side for a Common Earthball.


 Here's what it looks like inside:


A little further on I found these. 
 

Having found Dead Moll's Fingers Xylaria longipes a few weeks ago, I wasn't sure if these are a stubby example of those, or a not-very-stubby example of Dead Man's Fingers Xylaria polymorpha.

Here's a better view of one of those 'fingers'. I'm thinking it's Dead Man's Fingers Xylaria polymorpha but I'm none too confident about it.


This Ganoderma species was looking lovely and fresh, emerging from the base of this windblown tree (possibly Ash?).


I'm desperate to know if this is Southern Bracket Ganoderma australe or Artist's Bracket Ganoderma applanatum. But I haven't figured out how to separate the two (something to do with the size of the pores and spores – beyond my ken). I looked for the tiny galls which would indicate Artist's Bracket. Didn't find any.


Towards the southern end of the wood, the leaf litter gives way to a different kind of litter as Horton Wood lies adjacent to Horton Landfill site (now closed).

It was here, among the bottle tops and food wrappers, I laid eyes upon this little beauty.


I believe this a Russula of some kind. As the Collins (photographic) Guide says, their colour is "often fugitive." So this delightful dusky mauve cap doesn't tell me much.


It had a surprise in store for me when I turned it over, as it was home to these tiny creatures.


Investigations in the internet suggest these may be Nemastoma bimaculatum, a kind of harvestman. Bimaculatum means "two-spotted" and you can just about make out two spots in one of my photographs, if you zoom right in:


I wish I'd had as much success identifying the mushroom. What I can tell you is:
  • It's surprisingly un-brittle for a Russula, given their common name – the brittlegills
  • The skin peels to about halfway up the cap
  • The gills are adnate (more of less)
  •  It doesn't smell of much
And I've got a bit sitting on a piece of glass on my desk, in the hope I'll get a spore print.

So far all these features are a match for the Charcoal Burner Russula cyanoxantha, a very common species which is found in mixed deciduous woodlands. But I don't think I can get away with saying it's that.

The Amanita from Iping

Iping Common was looking glorious one Friday evening, a couple of weeks ago, when I joined the Sussex Wildlife Trust's wildlife guardians on a walk around the reserve.


Passing this expanse of heather on the right hand side, on the path which runs south west from the car park, we headed into a little patch of mixed birch woodland.


Here, by the path, I spotted this Amanita poking up through the grass: tall and tan and young and lovely.




I only got a couple of snaps as the light was fading and we were on a mission to see the Nightjars.

I've been umming and ahhing about whether this could be the Blusher Amanita rubescens or Grey Spotted Amanita Amanita excelsa. Two species which the Collins Guide says are "much confused".

I'd sort of convinced myself it must be the A. rubescens because my ID guides say the more common variant of A. excelsa A. excelsa var. spissa has a characteristic radish-like smell. And this mushroom didn't have a radish-like smell (I had a proper sniff). It didn't really smell of anything.

But I must admit, it didn't really display any blushing either (i.e. colouring red when cut or bruised), which is the characteristic feature of A. rubescens.

I happened to bump into Vivien Hodge today, who is a very experienced mycologist, so I grabbed the opportunity for a second opinion. She suggested it looks more like A. excelsa, but as I haven't got a clear shot of the gills it's rather difficult to tell. 

So I think I'm close on this one, but can't quite get to a species ID.

On Heyshott Common


Quick trip to Heyshott Common today produced this yellow Russula-type mushroom. It looked so much a part of this heathland scene I didn't want to pick it. So I just have a few photos to go on...

It had been raining heavily before we arrived and the cap was slightly slimy to the touch.


Beneath the yellow cap, the stipe and gills were a creamy-white.


There are a few different yellow Russula species which are typically yellow and white like this: Russula ochroleuca and Russula claroflava, for example. But the habitat here doesn't seem right for those species.

I'll have to admit defeat on this one and recognise I'll have to try harder if I want to identify Russulas to species.

I also passed by these rather diminutive earthballs. I picked one up to have a look at it and found it had no discernable stem it's probably Common Earthball Scleroderma citrinum, but I think I'd have to look at the spores to be sure.

Unidentified Bolete

Spotted on the walk home: a bolete of some sort, growing at the side of the road under a Hawthorn hedge.


The surface is heavily cracked, revealing yellow flesh.


Underneath, large angular pores of a dull, olivaceous yellow brown colour. They appear not to be bruising, although perhaps it's harder to see in an old specimen like this.

 

Not sure how you'd classify the gill attachment: adnate? Noted that the flesh discoloured slightly, to a dull green colour, where it was cut.


The stipe is fairly slim and tapers downwards – not club-shaped as you'd expect to see on a classic Boletus.

It has a fairly strong mushroom-y smell.

I'm guessing some kind of Xerocomus species (possibly Suede Bolete Xerocomus subtomentosus). However, there are many that look similar and the Collins (illustrated) Fungi Guide suggests that chemical tests may be necessary to separate these species with confidence.
