Ophioceras leptosporum?

Hello,

Found by a mushroomfriend, on Urtica.

Could this be Ophioceras leptosporum?

Ascus: 91.5 x 7.2 µm

Spores: 59.1-65.0 x 1.4-1.4 µm

Kind regards, Riet

Re : Ophioceras leptosporum?
Hello Riet,

Yes this matches P. leptosporum quite well, although the spores are rather (but not too) short (Iqbal 1970: 60-90 um). Important features include the long neck, thread-like spores without swollen cels and the ascal ring.
