Bonjour.Récoltes du 16/04/2026, sur feuilles mort
Hi everybody,I found this species on Impatiens and Meconopsis. Perethecia immersed, 0,1 mm. Spores (10-7) 8,4 x 2,95 (2,5-3) µm, hyaline, finly striate. Asci uniseriate, up to 70x45 µm, IKL negative.
Thank you,
Regards Maren
probably a Phomatospora.
Best wishes,
Gernot
Yes, and probably P. berkeleyii.
Alain
it is P. berkeleyi, described on grasses. I was confused because I didn't find the mentioning of the striation of the spores.
Regards Maren
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.

0320b-0001.jpgthe 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
