Coronophoral on Castanea branches
Enrique Rubio, 04-02-2015 14:24
Enrique RubioHi to all

I need your help again with this pyrenomycete growing on still attached branches of Castanea sativa near the sea. Unfortunately I can't to study well the perithecial walls and periostiolar region because the stromata are not well preserved. In fact I could not have observed  the existence of a quellkörper of another stromatic structures.


Asci + or – long stipitate and polysporic. Maybe they have 64 hyaline, cylindrical, allantoid, multiguttulate ascospores, 9.6-12.8 x 2.8-3.3; Q = 3.26-4.62, that seem have a dextrinoid region near the middle.


I don't know if this fungus could be a Cryptosphaerella (close to C. globosa), a Coronophora species or it belongs to another genus in Coronophorales.


Have you some idea?


Thanks again
