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
