I found the lichen growing on a stick (which i found on the ground, not on a tree). This was at an elevation of around 6500ft above sea level, found in a small area of cloud forest.

One of the felt lichens probably

Sticta or Pseudocyphellaria, I’d guess. Did you get a good look at the underside? Sticta has these perfectly round “craters” inset into the tomentum. Pseudocyphellaria has little raised bumps poking through the tomentum. (Both are adaptations to give the interior medulla more direct access to the atmosphere for improved gas exchange.) Yours looks like one of the species with cyanobacteria instead of green algae. That’s what gives it that lovely bluish hue.
