Pyrenomycet from south-ethiopia
Uwe Lindemann, 17-10-2009 15:11
Uwe LindemannHello Forum,
recently I found a Pyrenomycet on a dry twig at the Nechi Sar Nationalpark (Southethiopia). The Perithecia are embedded in a black stroma. The Asci are 8-spored, bitunicat, IKI+. The Ascospores are brown, globos, with coarse net, 22,5-29,5 µm.
Do you have any idea what kind of genus or species it may be?
Thank you for your help!
Uwe

Re:Pyrenomycet from south-ethiopia
Hi Uwe,
very nice find! I fist thought of a Biscogniauxia, one species does have reticulate spores but they are not globose and above all Biscogniauxia has perithecia embedded in carbonaceous stromata, while in your fungus the crust is only superficial.
Something to check first would be the presence or absence of a germ slit, or pore. Try in KOH to see it better.
Anyway i do not think it belongs to a xylariaceous genus known to me. As it seems to be in culturable condition,I suggest you to send it to Yu-Ming Yu (Taiwan). I guess he will love to see it!
All my best,
Jacques

Hi Jacques,
I don't see a germsplit, but I can prove it again.
I will send my find to Yu-Ming Yu. Is this the correct address?

P.S. If you like I can send to you next week two collections of the Xylaria on the pods of Millettia ferruginea from different places and a Hypoxylon species from the east of ethiopia.
