Pyrenopeziza on Cirsium palustre

Hi again


I'd like to know your opinion about this Pyrenopeziza species growing on dead stems of Cirsium palustre at 1400 m of altitude.


Tha lanceolate paraphyses have some inconspicuous hyaline VBs that stain in congo red (I don't know in Crb). Marginal protrudings absent, only a few hyaline short clavate cells are present.


I ask me if Pyrenopeziza lanceolata could fit well with my collection because this species is typical for Filipendula (in my region), the paraphyses are more clearly lanceolate and the hymenium is not so dark.


Could yo help me


Thanks again
