Good evening Forum,
I'd like to ask your help for an anamorph looking as densely grouped subulate spines on the bark of Acer.
Under the microscope I found 1-septate hyaline conidia of 8x2.6 to 9.4x3.4µ pointed at one end.
You should mark the branches colonized by the fungus in the field and keep an eye on them, because in a few weeks (depending on the weather, not until spring), the strongly gelatinous apothecia of a cream-colored Calloriopsis sp. will develop in the middle of the pycnidia. Have fun with the observations.
Cheers,
Guy
You're right Enrique.
I didn't know it was such a mysterious species.
Thank you very much
Thank you for the suggestion Guy. I will certainly follow it closely

I recently collected this mysterious fungus (ana & teleo) again on Salix twigs from a tree. This time no obvious association with a pyrenomycete (location the same as my earlier collection reported on this forum).
Interesting to learn that Von Arx has examined the type. Would it make sense to ask somebody at the Westerdijk Institute (formerly CBS, Von Arx worked there for a long time) whether they know anything about this particular type specimen or the study involved? The fungus has already been sequenced?
