Small Calycina(?) on Solidago

Viktorie Halasu, 08-11-2022 09:40

Hello,

I have here a small orange(ish) inoperculate on Solidago(?) stems, apothecia 160-220 um diam, paraphyses and margina cells with elongate VBs. Spore shape and size suggests Calycina, perhaps heterospora, but it wasn't reddening so intensively.
Some brownish structures on the margin = chalara anamorph or contamination?

Many thanks for any help.
Viktorie
