Schoenobryum concavifolium is rare in the flora area, where it is known only from Collier County in southern Florida; its presence there was undetected until recently (W. R. Buck 1994c). The plants are firm when dry and often have a shrublike aspect due to the erect, clustered branches. Terminal perichaetia give the branch apices a clublike appearance. The species is quite similar to Cryphaea filiformis but differs in its terminal perichaetia, single peristome, and the awns of perichaetial leaves that are only 1/5 the expanded portion of the leaf length. The two species have been collected growing together. In C. filiformis, also a rare moss of southern Florida, the perichaetia are lateral, the peristome is double, and the awns of the perichaetial leaves are 1/2 the expanded portion of the leaf length.
