Notes     (Last Modified On 5/4/2009)
general taxon notes:
Ptychomitrium fauriei is closely related to P. sinense. Both species have small plants and mitrate calyptrae, which cover almost the entire capsules. Ptychomitrium fauriei differs from P. sinense by having leaves with a suddenly narrowed ovate base and a narrowly lanceolate upper part, which is distinctly keeled and concave. In addition, Ptychomitrium fauriei is not as widely distributed as P. sinense.

Autoicous. Perichaetial leaves similar to upper stem leaves. Setae straight, reddish brown, 3–4 mm long, more or less twisted above; capsules erect, oblong-ovoid to cylindric, yellowish brown, ca. 1 mm long; annuli not well developed; peristome teeth long, linear, forked nearly to the base, finely papillose; opercula with an erect beak.
