Nono, scutuloid spores! Hymenoscyphus fraxineus, the epidemic.
Look the blackened substrate, surely petiole of Fraxinus.

Re : Rustroemia ?
Hi,
this would be the first record from Spain to my knowledge. But I don't see croziers...
What are the geographical data ? H. albidus we know from Pais Vasco only.

Regards Martin

Re : Rustroemia ?
You are right Martin, I was sleeping yesterday.... Indeed it is H. albidus, and we know of no other samples than smoe from Pais Vasco. So where did you collect, Javier?

Re : Rustroemia ?
Hello, 
I'd like to ask about the 4th image - aren't those two septa on the ascus base? Or is it just wrinkled / damaged after being torn from ascogenous hyphae? (I'm not saying anyone is wrong, just learning how to interpret what I see.)

Re : Rustroemia ?
I think the third image shows quite clearly a simple-septate base, also the fifth image suggests this. But one must be cautious, croziers may be hidden if not shown in side view.

Ah, it's in the eastern Pyrenees. If you have coordinates (or direction from Abella) and the date I would note that.
