Yes, I agree that it looks like Hyperphyscia. But I’ve been shocked before when turning one of these minute, closely-appressed lobes over and found rhizines! P. rubropulchra is extremely variable, and sometimes shows not even a hint of orange on the surface. It can have lobes that small easily. The one it’s growing over looks like P. pusilloides, and yes that’s clearly a good, honest Phaeophyscia. It’s “behaving” better than other Phaeophyscia.

Big ignore me, as a photo, this is indistinguishable from Hyperphyscia, so let’s call it that confidently! :)

9 o’clock Phaeophyscia

the picture obviously shows Phaeophyscia at 9 o’clock, but looks like this is different thallus and Hyperphyscia (?) grows over it? However it is in Botanical Gardens (Japanese Garden) – could be an import?

Phaeophyscia can masquerade as Hyperphyscia

That’s the only real alternative.

pruinose?

The picture taken 6 years ago. Just can’t think what else could be? I also have pictures of similar tiny lichens on concrete table in a park, but they have apothecia and globular soredia.

Hard one to verify by photo
