Thank you.
Acer pseudoplatanus is in that area, so it can be that one.

Re : With many conidia.

I collected one of the N. American species on Acer saccharum (P. acerophilum or acerinum, I can't remember) in 2016. It was late summer and very dry, nothing much to collect in the forest, when I saw a dead sugar maple with dark spores erupting through the bark. It was quite impressive, producing 3-4 cm long sori all over the surface of the tree.

Re : With many conidia.

Not sure where Oncopodiella came from . . .

Re : With many conidia.

Bonjour,
Si je peux me permettre et sans vouloir blesser quiconque, n'y aurait-il pas une coquille dans la fiche ?
