Re : hmm no rhizodiscina but what then?
Maybe Lecanidion atratum (= Patellaria atrata)?

Re : hmm no rhizodiscina but what then? reponse à cette question
Je suis d'accord avec la réponse de Enrique, il s'agit bien de Patellaria atrata. Espèce très
commune sur bois mort divers.

Re : hmm no rhizodiscina but what then?
No, it is clearly Patellaria atrata = Lecanidion atratum. There is a variant with a bluish hymenium in transmitted light, but yours is typically olivaceous.
