Notes:
Intriguing!
When I first saw the thallus of this lichen I thought it was a sterile species of Cladonia. But the size, shape and consistency of the lobes / squamules was totally different from what I’ve seen in that genus. After examining the photographs, I noticed that the lobes are actually very consistent, and each is divided into many sections each with a hole at the center, which can be an ostiole, or simply a hole (pseudocephalodia?). Also very intriguing is the existence in some lobes of a kind of bags that contain formations within a shimmering green, different from the rest of the thallus. Yet another strange thing can be seen at the bottom of the right side in the first picture: is this a preliminary stage of a fruit body?.
From the research I did, I found some species of Peltigera vaguely similar, and may even be a greenmorph of a Sticta, but again the resemblance is vague, since, in general, their lobes are not so consistent and are multiply bifurcated into branches.

not a lichen, but a liverwort – named after the shape of the structures on top of the thallus in which gemmae (vegetative propagules) are formed.
