Hymenoscphyus or Bryoscyphus? Yellow cup / white stipe
S. Rebecca, 09-10-2025 22:14
We just had the Bavarian Mycology Conference in Augsburg and my friend gave these ascos to me.

I try, but I am just not getting anywhere.


They were found in a field of unimproved grassland with Juniperus, and alongside the field were Fagus, Quercus, Crataegus, Pinus, Picea.


These Ascos looked like they were on an exposed root but under the bino they looked attached to Plagiomnium affina (ID google).


Largest Ascocarp ca 5-6 mm x 7 mm. Seems to be too large for Bryoscyphus.


Ascoporus blue in IKI.
Asci length 70 - 93 µm measured, p = 15
Spores 12-15 x 2.5 -3.5 (4) µm.
No Croziers observed
Does not redden.


Are the pictures enough to determine the genus?
Any chance at the species?

Hi

I have no clear idea based on your pics. The iodine reaction should be in the apical thickening, not at the apex. Not sure what that is. The reagent colour does not look like iodine?

The paraphyses are not clearly seen. Do they contain guttules?

The spores look eguttulate.

The ascus base I cannot see.

Is it possible that the stipe base sits on rotten wood?

The ectal excipulum is probably t. prismatica?

Hi Rebecca and Zotto, whats about Hymenoscyphus repandus here? Sure, the images are not very specific. But at least spore shape and measures and morphology of apothezia would fit ...
All best
Dirk

Hi Dirk, I also thought about this but the features are insufficient and the apos a bit large.

Hello Rebecca (I think I know you?),

nice to meet you here.

attached to Plagiomnium affina (ID google)".
"
surely not. There is no noss on the picture that has only a little similarity to Plagiomnium.

Google now tries to determinate mosses. Perhaps in some years ...

Yours, Lothar

Re : Hymenoscphyus or Bryoscyphus? Yellow cup / white stipe
Yes, same Rebecca.
Thanks for the info on the moss. I do not trust google and that is why I put on a question mark.

I just keep trying.

I did come across that Dirk. I will take another try to compare it to the description.

Thank you very much.

Re : Hymenoscphyus or Bryoscyphus? Yellow cup / white stipe
Thank you for having a look at this post.

I used Lugol.

I'll have to ask about the wood, I did not find this ascomycete, a friend did.

I'll try to work on it again today, the the ascocarp is still ok.
