Asco on Carex nigra
Simon Gurtner, 22-12-2024 10:19
Simon GurtnerHello,

can anyone help me identify this small ascomycete?

Found on 01.08.2024 in the Swiss Alps at 2220 m above sea level on Carex nigra.
So far, I have not been able to determine even the genus. Allophylaria is one idea. However, this could not be confirmed by sequencing.

I wish everyone a Merry Christmas and a Happy New Year.

Best regards,
Simon

Here is the sequencing:

Re : Asco on Carex nigra
why not a Cyathicula? Sometimes it helps to have spores, the reaction of the ascus apex with IKI and some further details.

Re : Asco on Carex nigra
Hi Lothar, when I created the thread, I uploaded the data before I was finished. I have added the missing images. Cyathicula was my first thought macroscopically. However, the microscopy does not fit.

Re : Asco on Carex nigra
Hello Simon,
ah - I was too fast. Now I see spores - but still not the ascus-apes in IKI. In Allophylaria it ist often (not always) reacting hemiamyloid.
What I already saw are guttulate (dying?) paraphyses what fits for Cyathicula - and for Hymenoscyphus. The excipulum seems more a prismatica than oblita, so o.k. better a Hymenoscyphus. The spores would fit here also better.
Yours, Lothar

Re : Asco on Carex nigra
Hi Simon,

to me it looks also as a Cyathicula/Hymenoscyphus, only the sequence does not make any sense. There is no attachment to Helotiaceae in the Multiple sequence ML tree.

Herzliche Gruessen, Frohe Weihnachten und ein gute Rutsch

Re : Asco on Carex nigra
Hallo Lothar, Hallo Stipe

Danke für eure Hilfe. Zu Beginn habe ich in der Ecke gesucht, bin aber auf kein Ergebniss gekommen. Ich werde es noch einmal da versuchen. Die Sequenz verwirrt mich mehr als es mir hilft. 

Grüsse, Simon

Re : Asco on Carex nigra
My guess was Cyathicula macrospora, and I remember a negative IKI reaction of the asci. I think the sequence is a contamination.

Re : Asco on Carex nigra
Hallo Zotto,

unter Cyathicula macrospora kann ich nichts finden. Meinst du Allophylaria macrospora?

Grüsse, Simon

Re : Asco on Carex nigra
... oder Cythicula megalospora? da hänge ich gerade im Schlüssel

Sorry, ja, megalospora
