Discomycete on Castanea
Gernot Friebes, 30-01-2018 14:52
Hi,

this one was also found by A. Gallé on wood of Castanea. The brownish excipular cells are very striking. The ascospores measure about 11.8–13.4 x 3–3,6 µm. The paraphyses contain VBs. Photos are by myself and A. Gallé. Thanks for your help!

Best wishes,
Gernot

Hello Gernot,


I do not know the species, but especially the spores strongly remind me of Encoelia.


Best regards, Lothar

Re : Discomycete on Castanea
Hi Gernot
yes, somewhat encoelioid. Do you have a pic of the VBs?

Re : Discomycete on Castanea
Hi, Lothar & Zotto,

thanks! I had not considered an encoelioid fungus. The VBs can be seen on the ninth picture – I attach a cropped and enhanced version of it.

Best wishes,
Gernot

Re : Discomycete on Castanea
Indeed Viktorie, it looks just like those. I cannot remember these two earlier samples, but found them via the host genus in my files under Cenangiaceae, folder "indet. Prunus, Hedera"

Re : Discomycete on Castanea
Thank you! These collections do look similar, although I'm not sure if the ascospore form is exactly the same; they tend to be bent in our material which I don't see in your collections. But who knows how much that can vary!

Best wishes,
Gernot
