Hello,

today I found a small urniform white hairy ascomycete of which I have no idea though it has quite striking features.

Biotop was a wet mountain meadow with Carex nigra, Eriophorum vaginatum. The apothecia were on very detoriated pieces of a gras, probably Eriophorum, lying on damp ground

The hairs agglutinate to teeth and form a dentate margin. The margin itself is formed by broadly clubshaped cells
Asci with croziers, appr. 70-75 x 9 µm, porus deep red in Barals (IKI rr 3)
Spores ellipsoid to ciborioid, appr. 9-9,5 x 4 µm, with ususally two to three medium sized oil drops and several more small ones.
Paraphyses filifom.

Can anyone give me a hint?

thank you and best regards,
Andreas

Hallo Andreas
must be a true Pezoloma.

Dear Zotto,

thanks a lot.

Pezoloma cilifera is microscopically a perfect hit - are there other species I should compare woth?

best regards,
andreas

I don't think so. One on Marchantia has much smaller spores, another has spores with a very high lipid content.

There is a key in Garcia & Van Vooren 2005 (here attached), but at that time the generic concept was very heterogeneous and included also Phaeohelotium/Cudoniella.
