Exidia thuretiana (Lev.) Fr.


In Dene Park, on the edge of the first Beech compartment I turned over a small branch and on the damp underside pressed against the soil surface I found what I think is the White Brain Fungus, Exidia thuretiana.  This photo, in natural light gives us some slightly blue and pinkish tones.


This closer photograph was flash assisted, but aperture controlled. It takes the tones out.


Here is another flash-enhanced sample. I think its fair to say that the margin is quite distinct here as expected, and the ridges are also at right angles to the margin, at least of the edge of the material.

Peniophora limitata and quercina perhaps

On the 22nd I found a crust that looked sufficiently like a rather decrepit version of Peniophora limitata for me to put it on the Fb page with a name, which Andy kindly agreed with. However it was on Oak wood (?) rather than Ash bark, so a little worrying there! |Importantly the margins did not lift.



On the 23rd I saw a crust on an overhanging oak branch above the Knight's Lodge path on the Beech compartment side. To me it looked thinner than the crust seen yesterday. There was much less blue-black staining, although the edges were turning up slightly showing the black under the edges and where the upper surface had apparently been lost there were patches of what looked like black under-surface material. The material was relatively well cracked with shallow cracks, not separating much, and I rather thought it was Peniophora quercina.


See the edges turning up, even if slightly, and the pattern of cracks.


Note the black underside exposed at the edges


The pattern may develop from individual patches.

Access Trail


This was on a long-dead Elm trunk along the Access Trail. Quite denticulate/papillate, with a slightly fluffy whitish margin. Lovely insulation around a wire effect!



A possible young Byssomerulius corium on a small branch by the Beech (Fagus sylvatica) shaw found on way back to The Forstal. Howver it could equally also be Basidioradulum radula.

This is also quite an interesting find - I think it just might be Byssomerulius asj well because under the hand-lens I could just see what appears to be the start of the wiggly undulations on the hymenophore. The hymenophore surface was a lovely light tan colour, but that layer appeared very thin, overlying a white felt-like fibrous layer that might just fit the description "un-encrusted". Overall the body is thin and was very easily sliced by my sharp knife, with no apparent "bleeding" at all.  The body edges are apparently turning up from the branchlet, even at this apparently young stage.



In the picture below you can see at the edges the white felt-like layer under the hymenophore.



Wood wart perhaps, possibly on Beech, and if so it might be the Beech Woodwart, Hypoxylon fragiforme, beside the Beech Shaw on the way back from the Access Trail by Hadlow.



Beetle hole I think into (or out of) the wood of the branchlet. One mm or perhaps two across. It is of course a whole little universe to be found in rotten wood.

Birch Woodwart, Annulohypoxylon (Jackrogersella multiformis) multiforme, I think.

Unknown fungus


I found (somewhere?) this rather odd partial bracket, partial resupinate. The fruiting body came away by breaking the surface it was attached to. The poroid surface had highly irregular "trapezoidal" pores breaking out through the surface, quite shallow whitish tubes projecting from a rubbery tough and fibrous white flesh. The "cap" surface was a dark ochre brown that was softly downy with a hyaline fuzz, rather attractive when viewed through a hand-lens.

Back to Dene Park



This Stereum is the right colour and general appearance for Stereum rugosum. But who knows?





This crust is whitish over dark grey., but there doesn't seem to be an obvious possibility in the books.



This one might be a developing Split Pore-Crust, Schizopora paradoxa - or something else!


and a closer view:


and this is staining by one of the Green Elf-Cups I think

Comb Wood, Wittersham


A bimble around Wittersham, meeting Chris as the neophyte Tree Warden for the Parish. We had a look at some street trees, the Village Green and Comb Wood. Comb Wood was very muddy and a friendly dog-walker was saying that the trees are very subject to windblow because the soil is clay on the Isle of Oxney and the roots find it difficult to penetrate deeply into the regolith, so forming a shallow rootplate. There were certainly quite a lot of leaning trees!

We saw possible Schizopora paradoxa, rather broken down, demonstrating the range of colours from cream to ochre. We also came across some Witches/Warlock's Butter, Exidia, possibly Warlock's Butter, Exidia nigricans ( = plana). We should have had a closer look at that, to see the surface details.

We came across some brackets on a very rotting log that I thought were Ganoderma australe/adspersum. The top surface was very solid and tough. I counted about 1-3 pores per mm. There is some conflicting evidence about this, suggesting much smaller, more closely packed pores, maybe 5-6 pores per mm for both species.

Chris sent in a photo of another rotting log with a possible Stereum subtomentosum, and what was likely to be the asexual (anamorphic?) stage of Kretzschmaria deusta. Fantastic!



The fungus list for Comb Wood stands at:

Schizopora paradoxa, Split Porecrust
Exidia glandulosa, Witches' Butter 
Ganoderma australe, Southern Bracket
Daedaleopsis confragosa, Blushing Bracket
Stereum subtomentosum, Yellowing Curtain Crust
Kretzschmaria deusta, Brittle Cinder Fungus
Hymenoscyphus fraxineus, Ash Dieback
