Hi forum, I'm now looking for another reference c
Arthonia sp.

I am studying a lichenized fungus with pinkish thallus, collected in Cantabria (Spain), along the Cantábrico Sea coast and growing on Quercus ilex wood. I have reviewed the "Arthonioid lichens", without the well-formed marginal exciple and find nothing like it. I'd like to hear your thoughts if anyone on this forum has studied these mushrooms.
Attached characteristics of the observed:
K-, C-, (I do not have access to P), I + blue hymenophore, acicular spores, sickle, 35 x 3-4 microns, hyaline at first, brown at maturity, 3 septa.
Trentepholia alga.
I would appreciate your opinions.
Greetings.

Re : Arthonia sp.
I do not see well the spores but could it be Schismatomma graphidioides (Leight) Zahlbr.? Check it!

Re : Arthonia sp.
Buenos días Javier
Creo que su sugerencia es buena.
Todo encaja en la descripción de la página:
https://wales-lichens.org.uk/species-account/schismatomma-graphidioides
Tendré que hacer mejores fotos de esas endiabladas esporas que se retuercen al salir del asco.
Muchísimas gracias.
