Pyrenopeziza on monocot.
Enrique Rubio, 22-04-2026 20:54
Enrique RubioHi to everybody.

This Pyrenopeziza grew in moist leaves of monocot. (Carex?) in a coastal lagoon in northern Spain. The apothecial margin is very briefly pubescent with short chains of cells with a clavate or broad bullet-shaped terminal element. Asci IKIb asci arising from croziers. Ascospores clavate with a broad obtuse base and a narrower, pointed apex. The lipid content is low or very low, consisting of only a few fine droplets near the poles (OCI=0-1) and remnants of a small apical gelatinous sheath that soon disappears (red arrowed). The paraphyses appear to have very little content and their apices possess an amorphous, almost hyaline or yellowish substance that reacts reddish in IKI. Excipulum textura globuloso-angularis texture of greyish cells.
There are some similarities with Peziza inapiculata Declercq, but I'd like to hear your thoughts.
Many thanks again

Re : Pyrenopeziza on monocot.
Pyrenopeziza karstenii is a quite variable species or species aggregate, I think this fits to some of the sampes in my folder.

Re : Pyrenopeziza on monocot.
Ah ! good idea !
In my collections of what I called P. karstenii , the apothecia appeared  with rather brown hairs and under the stem epiderm ''cut'' in an opercule .

Re : Pyrenopeziza on monocot.
Yes, this variation occurs. I think the species is little understood.

Re : Pyrenopeziza on monocot.
Yes, I think Michel is right. In this collection lacks the typical reddish-brown granular
exudate of P. karstenii, a characteristic that I have always observed in all my collections, despite its variability.

Re : Pyrenopeziza on monocot.
Such pigments may vary, we do not know. For instance, Durella suecica I remember dakr brown and whitish.
