Setose pyreno on Solidago
Gernot Friebes, 30-11-2014 16:38
Hi,

a friend sent me this pyreno on stems of Solidago. The collapsing perithecia seem to sit in a whitish subiculum and are conspicuously setose. Asci are unitunicate with a small apical ring and IKI-. Ascospores are hyaline, 0- to 1-septate, thin-walled and measure 5-7.5 x 1.2-1.5 µm. I couldn't observe a hamathecium consisting of „typical" paraphyses but it seems there might be some very thin-walled, hyaline, inflated cells between the asci which are pretty difficult to observe.
Any ideas for this fungus?


Thank you and best wishes,
Gernot

Re : Setose pyreno on Solidago
Ah right! Thanks Jacques, I should have thought of that. Let's see if I can find a full name for it now.

Best wishes and thanks again,
Gernot

Re : Setose pyreno on Solidago
Hallo Gernot,

ist damals bei dem Fund ein Ergebnis herausgekommen ?
Ich frage deshalb, weil ich einen ähnlichen, wenn nicht sogar gleichen Fund gemacht habe.

Viele Grüße
Thorben
