Observation 21410: Tuckermannopsis americana (Sprengel) Hale
When: 2009-05-29
No herbarium specimen

Notes: On a hardwood twig covered with several species of lichen, found in Zone 10 (one end of the “Miracle Mile”: Abies balsamea, Acer rubrum, Acer spicatum, Betula papyrifera, Picea sp., Pinus strobus, Populus tremuloides, and Quercus sp.; now I know why).

Based on chemical features: Need to do KC test on medulla to be absolutely sure it’s not T. orbata, but that species typically has more ragged edges, I think. (T. americana is KC+ red (weak); T. orbata is KC-) Both are probably present in your area.
