Distinguishing Features
A rare species of high altitudes and elevations, G. revolutum is variably red along its relatively wide (1-2 mm) and long (up to 5 mm) prostrate shoots of loosely overlapping leaves. The leaves are made up of two equal and rounded lobes, but along their sides that are “revolute”– they curl downwards (see photo). There are no oil bodies in the fresh leaves when inspected under the microscope.
Similar species
Red-hued species of Gymnomitrion are most likely to be mistaken for Marsupella. There are no cut and dried vegetative characters to distinguish between these two genera and reproductive structures used to traditionally seperate them are rarely present. Red species Gymnomitrion should be checked against small red species of Marsupella. See table for comparison to other regional species of Gymnomitrion.
Habitat
Moist to wet humus, cliffs, rock outcrops, seepage sites, heath, and tundra in the subalpine and alpine zones
