"Lasiosphaerioid"
Stefan Blaser, 19-03-2026 15:58
Hello everybody,

I hope for some hints...

Macro: Perithecia globose, black, glabrous, slightly tapered toward the ostiole, slightly furrowed around the ostiole, 0.4-0.6 mm in diameter. Perithecia always seated in a black mat (see below). 



Micro: Spores abruptly and strongly bent in the lower part, with a minute, rounded, hyaline appendage at the lower end, ca 1 µm long. Spores observed in Perithecia were always aseptate and hyaline, but (mostly overmature) Spores from Perithecial surroundings had 3 septa and were very slightly brownish. Spore size mostly 18-22 x (5)-6-8 µm (at the broadest part). Asci have a minute, inamyloid, refractive ring.


Black mat: This is a conidial stage with dark brown, fusiform conidia with a long, straight germ slight (as in Xylariaceae). I wonder if this actually belongs together with the Perithecial fungus?


Many thanks and best wishes,



Stefan

Re : "Lasiosphaerioid"
Thanks a lot Andy! 

I was greatly misled with my "conidia"...

In the field, I collected it as possible Chaetosphaerella phaeostroma, at home I considered Ruzenia spermoides first and in the end I got nowhere...until now.

Obviously not all that common in Europe. By the way, I forgot to mention the substrate which was a lying branch of Populus.
