Hyaloscyphaceae(?) on wood
Juuso Äikäs, 18-01-2020 08:13
These were growing on the underside of a piece of wood in a Picea abies dominated forest. The spores measure 6-7 x 3 microns, asci about 50-60 x 6-7. Both macro- and microscopically these seem fairly anonymous so I wonder if anything can be said.

Seems really anonymous... The hairs are only 2 µm wide as it seems. Doesn't look like a typical Cistella.

Hi Juuso, and Zotto


Seems to belong in Ciliolarina ? (difficult to give a species name, though)


Amitiés. Michel

Re : Hyaloscyphaceae(?) on wood
Hei Juuso,

Keep it in the fridge. I could take a closer look. Is it possible to deliver it fresh to Turku? I am back at the office next Wednesday.

No good suggestions. No match in Hyaloscypha what I can think of. ...well, yes, doesn't really fit Cistella, Psilocistella.. Seppo recently collected something that we thought is Psilocistella obsoleta, but it turned out to be aff Ciliolarina phylogenetically. And with smooth hairs!. It did not have slender hairs like here, so not suggesting this is it. Just saying that someone should take a better a look to Ciliolarina as well :-).

In every case, make careful annotations in the usual reagents (Cotton blue, MLZ, Lugol, water). Always let it "incubate" for a while. Some inclusions might stain. Also important if nothing observed!
