Observation 20360: Pseudocyphellaria hirsuta (Mont.) Malme
When: 2008-12-06
Herbarium specimen reported

Notes: Trunk of Nothofagus in dry, open, young forest near edge of field.

There are two very similar species apparently, both brown and hairy, with white medulla and pale yellow pseudocyphellae below, and with large marginal apothecia:

P. hirsuta — coarser, longer, denser hair
P. guillemini — more velvety, with occasional gold pseudocyphellae on top

I can see a few lobes with conspicuous raised gold pseudocyphellae on top in the photos. (Although I’d failed to record this in my notes.)

Update: upon examination of my specimen, it is clear that all the pseudocyphellae are on the undersurface; and moreover the hairiness is identical with several other specimens of P. hirsuta.
