On twig in damp dark oldgrowth Vadivian rainforest near waterfall in Anticura.
Key characteristics: green algae, white medulla and pseudocyphellae, smooth and glabrous surface above, dark brown tomentum below, apothecia with ragged “crown”, isidia/lobulae along margin and sometimes on surface (very few visible in this specimen).
Chemistry: usnic acid in cortex (KC+ gold), medulla trace amounts of various B-orsinol depsidones (K- or K+ weak yellow to orange).
Note, P. exanthematica shares most of the above features, but is strictly a southern species, ranging only up to 50°S.
