Asco on branch
Thorben Hülsewig, 19-05-2018 23:46
Hi there,

today i found this asco on a branch (Fagus sylvatica).
The spores are 3 Micrometer in diameter.
What could that be ?


best regards,
Thorben

Hi THorben,
the most likely option is Hyphodiscus theioideus.

Herzlich,

Re : Asco on branch
I have the same idea, and I would like to know the marginal hairs as well as the Lugol reaction of the ascus apex. H. theiodeus is fungicolous, it always grows on corticioid basidios like Peniophora.

Hi there,

that is it :)
I see also a corticioid basidio, but i didn't bother with him anymore.
Here are the marginal hair and lugol reaction pcitures.


best regards,
Thorben

Re : Asco on branch
Is it normal that the lugol reaction is so various ?

Re : Asco on branch
Yes, very good photo of the hairs.

The colour of the apical ring reaction simply depends on the IKI concentration (blue when low, red when high). This is type RB of hemiamyliodity.
