Observation Time: 9:10 a.m.

Observation Location: near Gavins Pond

Common Name: Common Greenshield Lichen

Scientific Name: Flavoparmelia caperata

Comments: The rock greenshield lichen looks very much like the closely related common greenshield lichen, but true to its name, it grows on rocks (only occasionally on tree bases), while the common greenshield lichen is almost always found on wood bark (almost never on rocks).
