Stem leaves oblong to oblong-lanceolate; margins crenulate at apex; apex rounded-obtuse, often broadly apiculate. Seta 0.5 mm. Capsule oblong, 1–1.6 mm; exostome teeth reflexed, papillose-striate; endostome segments 8, of 2 rows of cells, shorter than exostome, papillose. Calyptra naked. Spores 10–14 µm.
Habitat: Tree trunks, especially near base, dry, exposed areas
Elevation: moderate elevations (500-1500 m)
Discussion
Variety crenulatum is characterized by its oblong to oblong-lanceolate leaves with apiculate, broadly obtuse apices; the margins in almost all leaves are crenulate near the apex, and the seta is short. The exostome is papillose-striate as opposed to papillose. There are eight endostome segments and the capsule is strangulate when old.
