A pyrenopeziza-like disco on Agropyron
Michel Hairaud, 12-03-2017 23:16
Michel HairaudBonsoir à tous,

I am looking for some help for this newly collected fungus on dead stems of Agropyron acutum :
Asci IKI blue and H+ . 75-87 x 9,5-11. PS 40 µm
Spores 32-35 x 2,5-2,8, with rather large guttules . No septum observed.
Paraphyses whithout homogenous vacuoles but with round few refringent guttules staining in CRB.
Margin ''hairs'' up to 45 x 5 1-3 x septate,

The paraphyses content excludes Mollisia I think though there is a Plate by ENrique in Zotto's Mollisia pilosa file with rather similar spores. M. pilosa has other characteristics anyway.
I believe this collection belongs in Pyrenopeziza but there is no Pyrenopeziza species I can find in Litterature matching it.

Many thanks .
Amitiés. Michel

Hi Michel

it is clearly not M. pilosa, I agree, and I am similarly unable to say what it is. Vacuoles are in the paraphyses, but are they refractive enough to be a Mollisia?
