Collection location: MP 14.5 E. Larch Mountain Rd., Multnomah Co., Oregon, USA [Click for map]

Who: Daniel B. Wheeler (Tuberale)

No specimen available

Crustose lichen on rock (granite?). Rock may been imported to site, as Larch Mountain is mostly basaltic andesite, a common rock in Oregon, where volcanoes are eequally common. Most of surface is yellow and greenish-yellow. Black spots scattered over surface. I should know this one: very showy for a lichen.
