Re : Arthonia epiphyscia?
Hi,
You must give more informations. Are the ascomata perithecioid ? Could you also describe or show hamathecium ?
Best wishes,
Alain
PS : it could be Lichenochora obscuroides

Re : Arthonia epiphyscia?
Are you really sure of the identification on the lichen ?
What was its size ? Are soralia present ?

Re : Arthonia epiphyscia?
Hi Alain,
Yes, it is very similar to the Lichenochora obscuroides. I looked here over 100 lichen parasitic species, but this I missed.
I think there are two species of Physcia. P.adscendens (first picture) and P.tenella (second picture). If I'm not mistaken. Fungus are on P.tenella.
Ascomata is perithecioid (fourth picture, section)

Re : Arthonia epiphyscia?
The one you call P. tenella, parasited one, is not P. tenella. It looks rather like Phaeophyscia orbicularis, that is a good host for L. obscuroides.
