Re : black stromata in quercus
Hello,
Is the fungus rather forming acervuli? That'd be a rather flat fruitbody covered by the bark, and erumpant when the conidia's are mature. Could you measure the conidia's?

On Quercus (Quercus ilex?), that could be Coryneum elevatum. It's a coelomycete.
See Ellis & Ellis: Microfungi on land plants, an identification handbook. A good book to begin with for anamorphs.

Cheers - LUC.

Hola Luc,
it is an acervuli in Quercus ilex, conidia measures 40,45 X 21,09  --- 53,36 X 25,79 
in the  Sutton key of Coryneum, C. elevatum could be.
Un saludo
