Hello, Found by Laurens van der Linde, January 20
KOH gave a striking pink reaction at upper leves of the hymenium
cheers
Thomas
ps on some apothecia this fungus co-occured with Pyrenochaete xanthoriae
Hi Thomas,
It fits well with Arthonia parietinaria. Epihymenium id K+ for this species, but K- for A. molendoi.
Thus, we know (since 2016 , Fleischhacker et al.), that A. parietinaria occurs on X. parietina when A. molendoi occurs more on X. elegans.

Hi Martin,
Yes I noted this strange colour. But A. destruens is not given on X. parietina. Thus ascospores are bigger.
It would be good to check the reaction with next collections of Arthonia parietinaria. If I find time, I will check with mines.
Thomas, please keep it in herbarium under Arthonia sp. cf A. parietinaria.
Alain
