Bonjour à tous, Marcel LECOMTE président de L'A
Hi to all
This Anthostomella grew on wet dead stems of Ammophila arenaria. The fungus makes clypeate single blackish perithecia with papilate ostioles. Asci with a massive IKI positive apical apparatus longer than broad. Ascospores broadly inequilateral with spiral germ slit and peculiar partial gel sheaths at the poles. I think don't fits with A. spiralis or A. umbrinella.
Some idea for help me?
Thanks again
This could be Anthostomella lugubris, a species we find on Ammophila in our country.

Hi friends,
Again an amazing record of Enrique !
Clearly it isn't A.lugubris.
Closer than this last one is A. umbrinella, you saw it, but host and macroscopy don't fit. Thus appendages are lacking. Exit this hypothesis.
You can find it in Rappaz (into the genus Leptomassaria). Both species, L.simplex andL. unedo, are corticolous.
A. francisiae has such apical appendages, but the germslit is straight. Exit again.
My conclusion is that your Anthostomella is perhaps new.
Alain
I think so
Thanks again, Alain
