Can you help me with the identification of Acanthostigma species from Fagus wood?
I can not find nothing similar in the available literature.
Grateful before,

Re : Acanthostigma with Helicosporium anamorph
Hi,
A. minutum is possible. Helicomyces is an anamorpf, Fagus as host..... but what about the ascospores?

Re : Acanthostigma with Helicosporium anamorph
Chm.....ascospores seems to be asymetrical. 16-56um long? Chm.... seems to be NOT A. minutum. Something closer to A. ellisii....but probably not :-( At this moment no idea.

Re : Acanthostigma with Helicosporium anamorph
to me the "ascospores" seem to reprensent another type of conidia. I wonder if any are connected to the setose ascomata? Do you have any clear views of asci with this type of spores inside?

Re : Acanthostigma with Helicosporium anamorph
The spores you show are clearly conidia, perhaps Hendersonia.
