Ascomycet on old Peniophora quercina
Maren Kamke, 26-04-2021 20:38
Maren Kamke
Hello everybody,

I found this fungus with dark, encrusted, septate hairs, maybe of two kinds on Quercus twigs.

Asci 8-spored with croziers, IKI negative, spores ciborioid.

I'm glad about any help

Thanks

Maren

Re : Ascomycet on old Peniophora quercina
Hi Maren
Did you consider the possibility that it is a Dematioscypha? Are there any hyphomycete in the vicinity of the apothecia?

Re : Ascomycet on old Peniophora quercina
Hi Maren

do you have a photo of the hairs at higher resolution? I am not sure is it a Pyrenopeziza or a Hyphodiscus or ...?

Re : Ascomycet on old Peniophora quercina
Dear Enrique and Zotto,

I saw no Hyphomycetes around the Apothecia.

Here come two more pictures of the hairs and one with Baral'scher solution.

Re : Ascomycet on old Peniophora quercina
Ah, these are discrete, not too dense warts! Funny, and not unlike Hyphodiiscus. Anyway I am unsure and cannot remember such a fungus. This definitely excludes a Pyrenopeziza.

Re : Ascomycet on old Peniophora quercina
Hi Maren,

Do you do cultures & sequencing? This could well a member of the Hyphodiscus "family" as suggested. It would be interesting to place this one.

Re : Ascomycet on old Peniophora quercina
Hi Timo,
unfortunately, as a amateurmycologist I don't do cultures and have only had one fungus sequenced so far, so I haven't any experience with it.
If you are interested, I can send you the fungus for this purpose.
Regards
Maren

Hi Maren and Timo,
 
If you got material from Maren, and if your sequencing is successful, please let me know if it is this species or not:

I will load my sequence of such a species to GB when I have filled a gap of 300 nt in the LSU.

Re : Ascomycet on old Peniophora quercina
allright. I'll let you know how it goes. ---trying not to draw too much conclusions from ITS seq, but maybe this Guy's sequence is of a non aff. Hyphodiscus species?? It deviates a lot from the median Hyphodiscus seqs. ...an Encoelia???
