Meteorium (Bridel) Dozy & Molkenboer, 1848.

Meteorium is the type genus of the family Meteoriaceae, a group of mosses largely restricted to the tropics and to the Southern Hemisphere. It is basically a group of epiphytic Brachytheciaceae-like mosses with papillosity and with large auriculate leaf bases. Meteorium nigrescens has been found in Baja California, but it is so far unknown from California. Were it to be found, it would probably be recognized as a pleurocarpous moss whose spreading leaves are discolored almost jet-black on the older stems.
