Sphagnum capillifolium, the small red peat moss, is a species of
peat moss native to North America, including the Great Lakes
region. Sphagnum is a genus of between 151 and 350 species of
mosses commonly called peat moss, due to its prevalence in peat
bogs and mires. A distinction is made between sphagnum moss, the
live moss growing on top of a peat bog on one hand, and sphagnum
peat moss (North American usage) or sphagnum peat (British usage)
on the other, the latter being the decaying matter underneath.
