Boreal oakmoss is found in coniferous forests in cooler climates. In North America,
it is found throughout Canada and in the northern United States.
Identification: This is a fruticose (shrublike) lichen,
though its thicker branches remind me a bit of antlers. (Beard lichens and reindeer lichens have
thinner branches.) Boreal oakmoss is a pale yellowish green, and the branches are pliable,
not brittle. Branches are wrinkled and irregular,
more so if tiny reproductive structures called soredia are present.
Edibility: Contains usnic acid,
which causes severe dermatitis in some people, and, although this is not confirmed,
may cause liver damage if eaten.
