Should be smaller fruiting bodies. Figured coz there are thalus margins that fit to Arthonia. Loc.: Slovenia

Re : Arthonia graphidicola ?

Hi,


 Perhaps, but I don't see microscopical features. It's necessary to give an answer. Graphis has been identified as G. scripta, hasn't it ?


Thus, you should decribe ascomata : is it really arthrinoïd, or is it formed by perithecias ?


Other fungi occur on Graphis. The most frequent is Stigmidium microspilum, but it's a non-lichenized fungus. (here to compare : http://www.ascofrance.fr/search_recolte/3736 )

Re : Arthonia graphidicola ?
No microscopy possible at this point. Thanks for idea.

Is there somewhere a list on net in terms:
host lichen / guest ?

Re : Arthonia graphidicola ?

If it's a lichenicolous fungi, like your fungus on Graphis, lichenized or not, you can use :

Re : Arthonia graphidicola ?
Thanks.
Seems useful, but has some logical mistakes, See foristance:"Tichothecium latzelii"
Where is that in table ? Does that mean that after that is genus Endococcus (which I hope it is) or genus Tichothecium.

More nonlogical mistakes of that type there.
