Hi:

I found this small carbonaceous crust on hardwood. The size of the crust was 8 x 2.5 mm. Perithecia are about 500um diameter.
I do not get to see the germ slit at the spores, only I could observe it once, while the spore turned, he was on the less convex side of the spore and it has about 4um a length.
Looking at page Pyrenomyces I arrive at Nemania aenea var. macrospora. Do you think that determination is correct ?

Can somebody send me this article: The genus Nemania (Xylariaceae).
Nova Hedwigia. 74(1-2):75-120


Thanks greetings
Susana

Re : Nemania
Hola Susana,
your fungus looks indeed like N.aenea var. macrospora. It is a rarely recorded species.
I send you the pdf in private.
Cheers,
Jacques
