Pyrenopeziza on very wet hardwood
Enrique Rubio, 02-07-2013 18:03
Enrique RubioHi to all


On very wet hardwood my friend M. Tapia was found this Pyrenopeziza with white to amber pallid sessile ascomata up to 1 mm in diameter, attached by a narrow point to the sustrate. They are discoid, aplanate, never deeply cupulate and their margins are not pilose. The excipulum has the same color than the hymenium.


Asci whit conical apices IKI b not of the Hymenoscyphus type, close to the Calycina type, 8-spored, with croziers. The ascospores are clavate with a low lipid content. Paraphyses without conspicuous refringent Vb's. The excipulum is made by an angularis-subglobulosa hyaline texture becoming prismatica in the flanks and towards the margin. Hyaline short clavate hairs make the apothecial margin. 



I think is not P. dilutella but I don't know a species that fits well with this collection.
Have you some idea
?

Thanks again

Re : Pyrenopeziza on very wet hardwood
Hi Enrique

the eguttulate spores and smooth margin forbid P. dilutella. No idea, actually, but Pyrenopeziza seems acceptable.
