Gymnohymenial discomycete on wood
Viktorie Halasu, 16-12-2021 07:56
Viktorie HalasuHello,

these small tufts of asci grew on a bark of an Ulmus twig laying in leaf detritus, soc. Orbilia sp. No excipulum found, only those hooked to almost coiled paraphyses and asci. No free spores, asci weren't ejecting spores even after adding Lugol. Asci seem to be operculate and mostly H+ (some bases looked like H- but I haven't seen their attachment clearly). 
Would anyone point me to a genus? I guess something along Thelebolales, but all those I checked have either subglobose asci and/or are coprophilous. Riparian forest, 220 m elev.
Thanks a lot.

Viktorie

Hi Viktorie

this is not operculate. Conical apex with thick inamyloid apical wall in dead state we have often in Helotiales.

I think this belongs in the Laetinaevia uvidula group. I have a folder "uvidula-like, elongate spores" which contains photos by Blörn Wergen with just these protruding asci. His find was on Cirsium. The paraphyses vary but thy tend to be curved in typical unvidula too.

Dear Zotto,
thank you a lot, Naevioideae is a group I'm not at all familiar with.
