Re : Pyreno with striate ascospores
Thank you Gernot and Alain,
it is P. berkeleyi, described on grasses. I was confused because I didn't find the mentioning of the striation of the spores.

Re : Pyreno with striate ascospores
Please look at Mycotaxon 19, striation is well mentionned.
P. berkeleyii is usual on grasses, but it has been seen on other plants like Urtica.

Re : Pyreno with striate ascospores
Hi,
the original host is potato stalks. The type species is not easy to grasp and there may be several similar-looking species.
Maren, could you be so kind and send me some good material for culturing? We would need this to solve a rather "ancient" question about the position of another species.
Thanks, Walter
