... 6.7.24, alpine situation (near Glacier), same small bush (only about 0,5 m high) of Amelanchier ovalis than the last post (Hyalopeziza). With different keys I do not come to a good result - I end at P. (Mollisia) myricariae but there are some differences.
Unfortunately, the specimen was not fully ripe, so I did find only quite few (but some) free spores.
They contain few oil (few small drops, 0-1) and measure about 7,5-9/2-2,5 µm. The asci are IKI-negative and bear croziers. The marginal hairs are not very conspicuous microscopically (brown, like the prolongued excipulum), but macroscopically.
Who has an idea?
Best regards, Lothar

Re : Pyrenopeziza (?) from Amelanchier, French Alps
Urs Roffler and Javier Bometon have a specimen on Fraxinus and indet. wood in my folder "brown hairs IKI- 8-13 x 2", but the hairs are also microsc. very distinctive.
Mollisia myricariae is a synonym of M. ligni.

Re : Pyrenopeziza (?) from Amelanchier, French Alps
Hello Zotto,
thank you very much!
When I compare Pyrenopeziza "brown hairs IKI- 8-13 x 2" I find many common features and not obvious deviations - so this seems to be a good hint. Unfortunately one without a name - as so often.
Best regards, Lothar
