deeply cup-shaped white inoperculate with dentate hairs on ?Eriophorum - IKI rr

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

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.

Hello,

Very nice species.
I don't have any key for Pezoloma species.
Does somebody can send me one ?
Michel.

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.
