Some crusts for ID please

[JennyS]

These were taken yesterday and today in Oak, Holly and Hazel woodland.

On dead Holly - Diatribe stigma?


Q1. Similar to the above but seems browner, is it an Hypoxylon sp? It was on either dead Hazel or Oak.


Q2. In Oak, Holly and Hazel woodland but I cropped the photo's before noting tree species


Q3. In Oak, Holly and Hazel woodland


Q4. On dead Laurel. Not sure if this is a fungus but I've also seen it on Salix.


There's probably not enough detail for species ID on them but I'd be glad of clues as to genus!

Hi Jenny,

I hate crusts, but here goes:
1. D. stigma or even Biscogniauxia nummularia - they both look the same to me.
2. Yup, I think a Hypoxylon too, maybe multiforme, but this is supposed to be confined to Birch I think.
3. Looks like the wood is Oak which would make this Stereum gausapatum.
4. I couldn't decide if this was Radulomyces molaris or Steccherinum ochraceum - I'm going for the later because I have never seen R.molaris produce these 'pileate' forms (semi-bracket shaped) before.
5. Definitely fungal, but I have looked in Ellis & Ellis and FoS Vol 1 and although I can see something similar, there is nothing like this for Laurel or Willow hosts. (But I bet Andreas knows)

Neil.

Thanks Neil.
That last one is starting to bug me as I've seen quite a bit of it on dead and living wood ......
