Echria macrotheca?

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.

Hi Marc,
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.

Many thanks Michel and Peter.


I had doubts about it because the fringes on the sheath were not very obvious.

Re : Echria macrotheca?
As Peter and Michel said, this is clearly Echria macrotheca.
I've found it only few times. Surely a rare species!

We discussed it at Pilzforum.eu sometimes.
If you want to compare, look here
