Lichenicolous on Physcia

Lepista Zacarias, 10-04-2020 19:11

Dear all,
I would like to have your help in the identification of the lichenicolous lichen growing on a Physcia appearing in the attached photos.
I also attached photos from the microscpy. The spores are hyaline, guttulate, and mostly simple; some appear to have some central septum, being sligtly constrited there, with dimensions: 15.7 - 20.2 × 4.5 - 5.5 µm.
Thanks in advance,
