Grain O' Wheat Moss
HABIT: Small (4-13 mm), perennial, dark green to
blackish plants growing scattered or in loose tufts. Capsules immersed, obliquely ovoid and swollen on one side.
SPECIES: This species is similar to the
more common Diphyscium foliosum and occupies similar habitats. Diphyscium cumberlandianum can be
distinguished from the latter on the basis of its acute vegetative leaves and
smooth-awned perichaetial leaves. Diphyscium
foliosum has obtuse to rounded obtuse vegetative leaves and rough-awned
RANGE: This species is apparently
endemic to the mountains of the Southeast, where it is reported from AL, SC,
NC, TN, KY, and OH.
RANGE: First observed in 1988 in
Jackson County, a second locality was recently discovered in Hocking County.
STATUS: 1990-1991: Added, 1992 to
HABITAT: On shaded, moist or wet sandstone near
streams and on vertical cliff faces.
HAZARDS: Drying of the habitat; removal of forest
canopy shading rock exposures; overcollecting by botanists.
POTENTIAL: Unknown, but predictably
GUIDELINES: Collect minute samples
(area ca. the size of a thumbnail) and, if with sporophytes, only after spores
have been released.
COMMENTS: This species is restricted to the
unglaciated southeastern portion of the state and may be more common than
current records indicate. Intensive
searching should find additional locations.
Ohio currently represents the northernmost range of distribution for
this species in North America.
