Hi, Dear Jacob,

Maybe useful to try another genus. Beak of the perithecium is not seen (in genera of the Diaporthaceae and Melanconidaceae they always present).

Regards, Dimitar

Re : Diaporthe? on Berberis communis
I have checked, as far as possible,  in Wehmeyer's monographs (about Diaporthe - 1933), and about Melanconis and allied genera (1941). The stroma of your find looks like those of Melanconidaceae , but I don't know if the spores have appendages. If present - this fungus  could be attached to  Prosthecium (maybe an undescribred one), but I am not familiar with Prosthecium.
In Wehmeyer's monograph (1933) there are 2 species amongst the large spored ones - Cryptodiaporthe magnispora (Acer)  and C. pyrrhocystis (Alnus, Coprylus)  - but the spores are not constricted at septa and are much thinner (6) 7-9 micrometers.

Re : Diaporthe? on Berberis communis

Bonjour,


Before searching in Diaporthales, the first question should be : are the asci bitunicate or unitunicate ?

Yes, the right question  to answer. Thank you,  Alain!
