Dear community,

In all my Asco-Books I cannot find a key with all in Middle Europe ocurring Bisporella-species.

Is there any paper?

I show you, growing in Wienerwald near Vienna on lying Carpinus betulus stem:

Re : Bisporella (?)
Hallo Matthias

schöne Dokumentatoin! Also Bisporella ist heterogen, ich habe die gattung aufspalten müssen, da gängige Arten eng mit calycina verwandt sind und ich entschied, sie dort einzuverleiben.  Also es heißt da bei mir jetzt Calycina citrina statt Bisporella citrina.

Dein Fund ist im Prinzip C. citrina, aber falls Bisporella confluens eine Berechtigung hat, dann ist es die wegen der langen Sporen und eventuell auch Asci. Die habe ich nicht umkombiniert wegen meiner Zweifel.

Re : Bisporella (?)
Not a comprehensive taxonomic one, only the combinations and a very short text about the generic features I published some years ago. A description of  B. confluens by Korf & Bujakewicz and two recent papers on Calycina from Macaronesia partly dealing with species formerly placed in Bisporella are in your mailbox.
