Caloplaca cerina is an underdog.

I just added another photo (at the bottom), where C.cerina serves as an arm-chair to C.holocarpa. So it’s not just Phaeophyscia that takes advantage of C.cerina here, but another Caloplaca species too. (We all know some relatives who are worse than enemies :-)

Yes, it is very striking

I wonder if it’s just a matter of the Caloplaca providing better texture for capturing spores or algae or moisture or nutrients or something?

Yes, it’s aspen

I actually find it entertainig how Phaeophyscia grow right out of Caloplaca thalli.

On aspen?

Wish those Phaeophyscia weren’t interfering. Those could have been beautiful rosettes of Caloplaca!

+ C.holocarpa?
