Who: Jason Hollinger (jason)

Specimen available

On bare trunk of Nothofagus near tree line on lower slopes of Volcan Casablanca. Well-lit near edge of forest on bench over permanent river.

This is supposedly a rare species, seen only on the slopes of this volcano and Osorno (presumably occurring on any of the numerous other volcanoes in the area, as well). It is distinguished by its closely-appressed pale gray to green, flat, thick, densely pubescent lobes; yellow medulla and pseudocyphellae below; brown to matte-black apothecia not very common. Central parts may be glabrous in age, as well as lobulate (not seen in this specimen). It is further distinguished from the much more southerly species P. endochrysa by its lack of linear yellow pseudocyphellae running along and just beneath the margins (and longer, denser hair on the surface).

(Busted! Sorry, I did collect a number of lichens from this particular area in the park because I was so far from any trails…)
