Hyaloscyphaceae on Populus wood
Stefan Blaser, 14-02-2014 10:50
Hello everybody

Can anyone give me some advice on this Hyaloscyphaceae?


It grows abundant on a Populus log.


Macro:  See Photo. Size up to around  1 mm in diam.


Micro:  Asci 50-60 x 5-6 µm, hooked, porus IKI blue. Spores mostly slightly clavate, 9-10.5 x 2.8-3.5 µm. Paraphyses nearly cylindrical, 1.5 µm diameter, abundant and rather adhesive to each other.  Margin with hairs. These are hyaline, thin to slightly thick-walled, cylindrical, mostly naked, agglutinated, 2-3 µm in diameter. For more details see photos.


Thank you for any help


Stefan

Re : Hyaloscyphaceae on Populus wood
hi stefan, it looks more like a cistella to me. i think there are little warts on the hairs (apikal) sometimes? it seems so ... c. dentata would be an idea.

best

Hi Dirk

Yes, there were small warts at the apices of some hairs! And from a first quick search, Cistella dentata seems to fit with most microcharacters.

Thanks a lot!

Stefan
