Is this 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
Are you really sure of the identification on the lichen ?
What was its size ? Are soralia present ?
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)
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.
