Amerosporous pyreno on Picea
Gernot Friebes, 01-08-2014 20:25
Hi,

I found this species on a decorticated branch of Picea abies about 2 m above the ground, assoc. with Pseudographis pinicola and Orbilia sp. (immature). Asci are apparently bitunicate although at the same time they appear to be rather delicate. Ascospores are non-septate, hyaline, smooth, and measure about 9-13 x 4-5 µm. The hamathecium consists of hyaline, filiform, pseudoparaphyses-like structures. No reaction in IKI observed. Any ideas for this fungus?

Best wishes,
Gernot

Hallo Gernot,

I do not know what that is, but I am sure I had the same from "Weißensee" (Carinthia) in 2013 (on Picea abies). See attached photos.

regards,
björn

Hi Björn,

thanks, that looks quite similar indeed. My find is from Carinthia as well - Seebachtal bei Mallnitz.

Best wishes,
Gernot
