Hello again,

I have found a Diaporthaceae on Genista with the following features:

Perithecia clustered, sphaerical with a beaked ostiolus, black, reminds on D. strumella.
Spores broadly ellipsoid, hyalin, first with a few bigger guttules, then filled with many small ones, with a central septe and a constriction there, smooth.
Asci with 8 spores (uniseriate), ca. 100-150x10-12 µm.

Found on dead stems of Genista. I didn't find any literature about this species, unfortunately Ellis&Ellis didn't mention it under Genista...

Is it D. genistae? I know about Diaporthe-species with their relation to specific substrates but its just a guess, perhaps somebody can give a hint for literature ;)

regards,
Kazuya
