Europe. North America. The North American distribution will be clarified by Atwood (FNA vol. 29, in prep.).
On bark of various trees in humid stream ravines and dry oak-hickory forests. Occurrences on rock are common. Apparently a lowland species with scattered known occurrences in the Southern Appalachians.
Shoot width: to 1 mm. Color: green to brownish Cell walls in leaf lobe: without intermediate thickenings. Dorsal lobe insertion: truncate. Lobules: about as wide as long when inflated.
Monoicous. Perianth surface without turbercles; perianth with supplementary keels dorsally and ventrally
Two entities Schuster (1992) considered to be synonymous with F. inflata, F. rappii (large trigones), and F. saxicoloa (perianth mouth occluded by papillae), will be recognized as distinct species by Atwood (FNA vol. 29, in prep.). Neither taxon is yet known from the Southern Appalachians.
A very frequent species in the southeastern U.S. but not well known from the Southern Appalachians where it appears restricted to lower elevations.
