Pyreno on Ribes petraeum

Enrique Rubio, 25-06-2013 19:10

Hi to everibody
This fungus makes small (up to 0.5 mm), erumpent, superficial, blackish and sub-glabrous, roundish pseudothecia on branches of Ribes petraeum at 1700 m of altitude. It has isolated or more commonly aggregated of many pseudothecia on the bark of branches lying on he ground.

The asci are bitunicate and the ascospores are hyaline and 1-(3) septate, constricted at the septum and with a thick sheath. Pseudoparaphyses trabeculate are present.

Maybe a Massarina species?

Thanks again
