The first 6 tables show surely one species with 2
Apothecia discoid, black, growing on wood of Quercus.
Size up 800um diameter.
Spores hyaline with 9-11 transverse septa and 1-2 longitudinal septa.
IKI (-). Asci containing many conidia?
Paraphyses filiform, septate, divided. (x 1-1.5um).
I think it may be next to Patellaria, but I have no information.
Any ideas.
Thanks in advance.
Susana (Spain)
please compare Claussenomyces atrovirens.
Attached a plate by Hosoya (2004).

Encaja perfectamente.
Un saludo

I fully agree with Martin's ID. Did you collect on Quercus robur/petraea or was it a submediterranean or mediterranean site?
Zotto
The sample is collected in Sarasibar (Navarra).
The oak that grows in this area is Quercus petraea.
The climate is submediterranean? or Subatlantic? I leave a link if you have interest.
