Two odd fungi for ID please

[wildlifepilgrim]

This one was high up in a tree. The white disk was about 2cm across growing on a twig.





I thought this was badger dung for a moment until I saw that it seemed to be growing out of the log. Any ideas about what this might be?

Hello,

no idea on the first one, except that it is a polypore . Looks interesting, but also looks quite immature.

the second one is Coryne dubia, the asexual form of Ascocoryne sarcoides.

best regards,

Just wondering if Byssomerulius corium is a possibillity for the first images.

Cheers J.P.

Although the pores look like they will be too big, I suspect this may turn out to be just Bjerkandera adusta, but 'high up in a tree' ?

i recently found Bjerkandera adusta on dead birch which was about 15 feet tall and they were from about 2ft up the trunk and right up to the very top where it had broken off, it had been quite a large birch,
do they normally grow at low level ?

see here, Bjerkandera adusta ?

I saw that post, but made no comment as I was only 99% sure it was B.adusta
I too have seen it high in trees but from my own experience I find it mostly on dead tree stumps.

Neil.

the ones i have found on stumps turned out to be Kretzschmaria deusta
which was why i was unsure of my find on the birch, (still very vague on the id of both these species )

Kretzschmaria deusta is not only more difficult to spell, it is more difficult to identify as it has 2 distinct stages of growth - the white/grey infertile stage, followed by the black 'Brittle Cinder' stage.

Luckily it is very common on Beech stumps or in cavities, so is an obvious choice to make. It should be difficult to confuse with Bjerkandera adusta as this is only gray on it's fertile layer underneath an obviously more defined small bracket.

Hello Neil,

resupinate growing Bjerkandera adusta and the anamorph of Kretschmaria deusta are very very similar in appearance. I had that several times in my courses, that people mixed that up. Of cours, when you touch it, it is evident. But just from looking at them while strolling through the forest - very easily to confuse in my opinion.
