Hello Ismael,
compare Rutstroemia echinophila.
Best regards, Lothar

Re : Hairy cup on cupule Quercus
Ok are you sure? Is that also so hairy?

Re : Hairy cup on cupule Quercus
To me this looks more like appressed fibres than hairs. I agree with Lothar. Is this a submediterranean Quercus?

Re : Hairy cup on cupule Quercus

Re : Hairy cup on cupule Quercus
I found R. echinophila in Germany (Eifel) on deciduous Quercus (robur or petraea) leaves. And I remember, Zotto, decades ago I also found it here in the South of Germany on Quercus leaves and you then determined it.
I think few fungi tell apart between Castanea and Quercus.

Re : Hairy cup on cupule Quercus
I can't remember, Lothar. In my files and database I have no hint on leaves. The difference to R. petiolorum is not easy, isn't it?

Re : Hairy cup on cupule Quercus
Petiolorum I only found on Fagus leaves, sydowiana on Quercus. I think petiolorum is much smaller and looks macroscopically different. I do not have in mind the microscopical differences.
The find of echinophila that you saw on Quercus leaves was not documented by you, only shortly looked at and determined. I do not remember in the moment where it was found, but possibly I would be able to find it out with time enough ....

Re : Hairy cup on cupule Quercus
It is smaller but we do not know how large Ismael's apos are. A crenulate margin might be a difference. What surprizes me is the almost black disc, as if it were a Lambertella with finally brown spores.

By the way, Hymenoscyphus sparsus I had mostly on Quercus but sometimes on fagus, similarly Dasyscyphella nivea. But Rutstroemiaceae might have a narrower host range.

So I must not have made a note in my database about this find on cupules. I only know records on Quercus cupules besides Castanea cupules.
