Silverleaf fruit bodies possibly

On a small log by the old farmhouse moat, Fairlawne land.

Andrena sp burrow

Amazing burrow of one of the mining bees, Andrena sp. Found in their 100s on the path surface on Fairlawne land.

Birch woodwart

In Dene Park the other day I came across a medium-small standing Birch trunk with lots of these brown to black lumpy fruiting bodies bursting out of its bark. This is the Birch Woodwart, Annulohypoxylon multiforme, aka Jackrogersella multiformis, a fungus in the Pyrenomycete group of Ascomycetes, most commonly noted on Birch although it occurs on a range of deciduous trees. Another species of Dickrogersella exists in two different forms, on Beech and Oak respectively.

The fruiting body is rather formless at first, often an ochre-brown in colour, and as it ages it darkens, and starts to form these multiple black perithechial bumps, with papillate (sometimes in a little depression) ostioles or spore-releasing holes. It would be interesting to do a cross-section to see the perithecia.

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.
