Hi, I found numerous seeds of Washingtonia robusta
I found this Pyrenomycete, growing on a herbaceous stem.
I think it may belong to the genus Pyrenophora, but I have no documentation to define the species.
Perithecia up to 600um diameter. With abundant hairs septate, thick-walled, apex rounded and size 400 x 12um.
Asci of 300 x 35um.
Spores, with 5 transverse septa and one or more longitudinal. Measured size up to 72 x 29um.
What do you think about it?
You can send information from the genre.
Thank you, greetings
Susana (Spain)
rather looks like Pyrenophora phaeocomes. I am in a hurry, otherwise I would check myself. I will give you more information this evening.
Probably you can send me the photos ;)

Thanks, I send you photos. And I look forward to information about the genre.
greetings.
Susana
thanks for sending the photos. Your species fits well Pyrenophora polytricha, which is described as having hairy ascomata with 5 septated ascospores. Only the sizes of the ascospores are a bit larger than given in Wehmeyer 1961.
Furthermore I think the substrate is a gras, maybe Scirpus or Triticum. I am not a specialist in "gramines".
regards,
björn
