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.

björn

Hi Björn,

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

Best wishes,
Gernot
