These tiny (0.4-0.5 mm diam.), whitish, short-stip

Good evening everyone,
On dung of sheep I recently found perithecia of about 650x500µ with tufts of agglutinated and septated brown hairs.
The asci were long-stipitate, 230x45µ and 8-spored.
I could only find a few spores outside the asci. They all had a gelatinous sheath that was slightly fringed and measured about 45x24µ
Following Nordic Sordariaceae, Lundqvist I came to Arnium macrotheca, now Echria.

my mushroom friend Sven has found this species last year in cow dung. I could also examine the test and confirm the finding also. Perhaps Sven announces himself, he has of it a good documentation.
Greetings Peter.
A. macrotheca, nice find, unusual species.
Michel.
Many thanks Michel and Peter.
I had doubts about it because the fringes on the sheath were not very obvious.
Marc
I've found it only few times. Surely a rare species!
We discussed it at Pilzforum.eu sometimes.
