Psilachnum ? on Equisetum hyemale

yesterday I found im botanical garden Bochum this asco on Equisetum hyemale.
My guess was a Psilachnum, but now I am not so sure.
The marginal hairs are curved (like claws) and partly glued.
There are 2 types of spores (the short and the long spores).
Both spore types are formed in the ascus, unfortunately I don't know if all asci are 8-spored.
Any idea what this could be ?
best regards,
Thorben

Re : Psilachnum ? on Equisetum hyemale
Psilachnum inquilinum is a species that grows on Equisetum and has hairs thar are apically bent. Where I live it seems to be fairly common. Maybe this could be that? Zotto has earlier mentioned that there is a species with bigger spores that grows on E. hyemale. The two-sized spores are maybe a bit weird? Are they from different apos?

Hi Juuso,
i think your idea with Psilachnum inquilinium is not bad.
The two-sized spores are in all Apos present. That's why think it belongs to the fungus.
I see also only the Psilachnum apos on these substrate and some Hydropisphaera, but no other.
I saved it as Psilachnum cf. inquilinum and wait until i can collect more material.
Maybe the other material doesn't have 2 types of spores.
best regards,
Thorben
