On Nothofagus trunk in open montane forest.
I can’t decide for sure whether this has green algae or cyanobacteria. It has white medulla and pseudocyphellae. But what are the schizidia on the margins? Are those eroded isidia or soredia?
I have another specimen supposedly, from near Rio Grande on Tierra del Fuego which is all black below.
