Reindeer Moss


any lichen of the genus Cladonia, including C. rangiferina, C. alpestris, and C. sylvatica. Sometimes only the first species is called reindeer moss. Because of their bushy, heavily branched layers, the lichens are occasionally separated into the genus Cladina. It provides good fodder for reindeer. Some species contain usnic acid, which has antibiotic properties.
