Observation 95855: Umbilicaria hyperborea (Ach.) Hoffm.
When: 2012-05-27
(46.896° 119.3702° 801m)
No herbarium specimen

Notes:
Substrate: Basalt.

Habitat: Sagebrush Steppe, totally exposed.

Oddly, this guy looked an awful lot like what I’m now thinking is Collema fuscovirens, the thallus on both being kinda knubby, similar location on the rocks in relation to soil and aspect chosen by both too, and growing a couple feet apart; I assumed the Collema was an Umbilicaria without visible apothecia. But seems like the Umbilicaria genus doesn’t usually form such well developed rosettes as Collema? Seems like from the photo that this one may be Umbillicaria hyperborea.

Yes, definitely U. hyperborea

That “bubbly” surface is very typical (characteristic, even!)
