Collection location: Southeast Portland, Multnomah Co., Oregon, USA [Click for map]

Who: Daniel B. Wheeler (Tuberale)

No specimen available

Until I got back home, I didn’t notice that this tiny yellowish-green lichen is composed almost entirely of tiny cups, the edges of which are higher than the surrounding thallus (hope I got that right). How to describe how small this is … entire field of view is about 3-4 inches, so each cup is less than 1mm across. Got to get that disecting microscope, I guess.

Recognized by sight: Candelaria is the same color, but would be mostly lobes and few apothecia. Xanthoria would be oranger. Candelariella vitellina is common on rocks throughout the west; I’m not sure what would be on bark.
