Cudoniella tenuispora: Distinctive macro and habit
Dermea on Prunus

I collected a Dermea on Prunus (likely P. spinosa), which, unfortunately, didn't produce any conidia (even though conidiomata are apparently present, see macrophotos). Is it possible to identify it based on the sexual morph? The ascospores measure about (13.5)15.8–17.5 x 3.9–5.2 µm. Thanks for your opinion!
Best wishes,
Gernot

Re : Dermea on Prunus
Hi Gernot
Usually this is Dermea prunastri. Descriptions in the lit. are quite inadequate. I remember the conidia were not well figured.

Re : Dermea on Prunus
Hi, if everything is not deceptive we had here already a discussion about Dermea, I do not find the contributions, unfortunately, because the search here in the forum not work.
Greetings Peter.

Re : Dermea on Prunus
Thank you, Zotto and Peter!
I did read that discussion but it is mainly about the size and shape of the conidia, so not particularly helpful in my case, unfortunately.

Re : Dermea on Prunus
I think the species are too similar in the asci and spores to permit distinction. Only I remember that D. cerasi has inamyloid asci (perhaps not always).

Re : Dermea on Prunus
That was my impression as well looking through your Google Drive folders, but that is still a good thing to know!

Re : Dermea on Prunus
Hi all, thanks Zotto, there was at other place a discussion about that point.
Up to now I had only the possibility, sexual stages of D. cerasi and prunastri ("padi") to examine, no distinction was possible there for me, I have not exhausted, however, definitely yet not all possibilities. However, I would not maintain broadmindedly, that the species shown by Gernot D. cerasi is only, because at the same moment both stages are to be seen.

Can somebody say to me how the search- function can be activated in the forum?
Greeting Peter.
