Bonsoir à tous,Voici une récolte du 14 août der
Setae septate 80-250 um, conidia 5-6 x 2 um.
The characters match well with Pyrenochaet fallax as described by Ellis & Ellis 1997. The host listing of Urtica dioica in the US fungal database (https://nt.ars-grin.gov/fungaldatabases/) includes only this Pyrenochaete. Furthermore, Schneider 1979 (Die Gattung Pyrenochaete De Notaris,) mentions only one other Pyrenochaete collected on Urtica: P. rhenana but this species has long hairs forming a subiculum.
Can somebody comment on or confirm this identification?
Thanks in advance, Eduard
