Cladonia spp.

Cladonia rangiferina, Cladonia uncialis and Cladonia furcata      1 cm    

Common species on lowland bluffs near salt water in western Washington.  Cladonia furcata is the greenish gray species interspersed within the whitish C. rangiferina and the yellow-green C. uncialis.  C. furcata is highly variable and found throughout western Washington.  Cladonia rangiferina was recently transferred back into the genus Cladonia, where it had first been described.  For many years this has been called Cladina rangiferina.  Whatever the scientific name, the common name of the wide-spread species is "Reindeer Lichen"
