It was only a thought… Good luck!

Doesn’t seem like Dibaeis baeomyces.,

though I never found this species and it doesn’t appear in any portuguese cheklist (mainland, Madeira and Azores). I don´t know what it could be.

I was tending to Trapelia, and since D. baeomyces would grow on soil and these are on stone, Trapelia sounds a more reasonable guess. The only problem is that I only find a similar photo or two (without pinkish shade) and with a interrogation mark (“Trapelia placodiodes?”) http://www.stridvall.se/lichens/gallery/Trapelia/NIKB1041

If it really is _Dibaeis baeomyces, it should have baeomyceic, squamatic, and barbatic acids: K+y, C-, KC-?, UV+ white, P? Could help confirm or refute the hypothesis at least…

Bravo Jason, it could be, I was a little lost :)

I think we have, though I haven’t find it yet, but Zaca would know better about this.

Probably not but…

This looks a little like the sterile form of Dibaeis baeomyces. Do you have that species over there?
