¿Stigmidium?

Re : Lichen on Marchantia polymorpha

It looks like Steinia geophana, which may grow on various substrates - sandy/clay soil, wood, decaying macrolichens. I can see 16 (sub)globose ascospores per ascus, and rather short simple paraphyses unthickened at apices. You may also check for amyloidity of the ascus apex. Zdenek

Re : Lichen on Marchantia polymorpha

Thanks Zdenek,
right into the center, I`ll check amyloidity.
