Pyreno on unknown wood

Thorben Hülsewig, 11-04-2020 11:15

Hi there,
yesterday I found this Pyreno on an unknown piece of wood, in a creek.
Do you have any idea what it could be?

best regards,
Thorben

Re : Pyreno on unknown wood

Hello.

Could you show us the apical apparatus in blue-black Waterman ink ? Could you check too if ascus are unitunicate and if they are IKI- ?

It could be the common Ascitendus austriacus.

Re : Pyreno on unknown wood

Hi, Yannick,
I did some more microscopy and the asci are IKI-, but outside there is a red color.
The spores are smooth and mostly 3 septated (rarely 4 septated).
Probably the macro photos are from the second Pyreno, because my Pyreno has Setae.
My fungus has some similarities with Capronia sp. 'macrospora' from this thread here:

best regards,
Thorben
