Re : Diaporthe? on Berberis communis
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!
