Diaporthe genistae?

Björn WergenHello 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

Hi Kazuya,

D. genistae is something different (see attached original description by Rehm). Compare your find to Diaporthe inaequalis which can also be found on Genista.

Best wishes,

Gernot

Re:Diaporthe genistae?
hmm thanks Gernot for help, D. inaequalis has spores around 12-18x7-9µm (see Ellis&Ellis 1997). The spores of my finding has 17-21x8-9. If the different size isn't a problem, it could be D. inaequalis ;)

regards,
Kazuya

Re:Diaporthe genistae?
Munk (Danish Pyrenomycetes) gives 16-24 x 8-12 µm for D. inaequalis, so quite a huge range.

Best wishes,

Gernot

Re:Diaporthe genistae?
It seems as if my literature is not good enough for me to make larger studies about pyrenomycetes :D
thanks again Gernot, if you have some material about Diaporthe, I am always interested ;)
