Phlyctis petraeaObserv.
mjpapayDescripción
Observation is for the dome-like, yellowish-green lichen growing on the dust lichen (Lepra finkii).
It is, to an old Rockhound like me, interesting that the mineral Wavellite has a similar appearance in form and color (light green to white).
EDIT, 02 December 2023:
1). I found this same species abundantly adorning the bark of a Maple: https://www.inaturalist.org/observations/192858462
2).
- Phlyctis petraea is the host lichen (a common species on siliceous rocks)
- The powdery chartreuse green granular domes appear to be the spores of an undescribed lichenicolous lichen (perhaps Tremella ) that is parasitic on the genus Phlyctis.

mjpapayDescripción
At the center of the photo is a large mature thallus. In the field I was mistaken when I thought the protrusions on its surface were apothecia (of which I was admittedly excited). However, upon examination of the photos on the computer, I realized my mistake. But what are these protuberances? Perhaps they are manifestations of an infection by a fungus, such as Tremella. The Flora of Lichenicolous Fungi, 2022, pages 265-6, refers to a Tremella umbilicariae that infects species of Umbilicaria, of which the genus Dermatocarpon is related. However, the contents of Flora of Lichenicolous Fungi, 2022, does not include a reference to Dermatocarpon. So, at the moment Tremella is the best fit. A separate observation has been made for the Tremella : https://www.inaturalist.org/observations/192664957
