    Species Description - Plants 15-20 mm high. Stems with a strong central strand (but occasionally hollow) and a hyaloderm; axillary hairs hyaline. Leaves up to 4 or 5 mm long, somewhat broadened above a short, erect base; margins bluntly and remotely serrate above the middle, serrulate below (usually nearly to the base); costa percurrent, covered ventrally by short, bulging mammillose cells and dorsally by elongate, smooth cells, with 10-16 guide cells in 1 layer and hydroid strands (Begleiter cells) below and sometimes above them and 3-5 parenchymatous cells between the ventral stereids and the epidermis; upper cells 9-12 µm; basal cells 10-18 µm wide. Autoicous (reported to be synoicous as well, perhaps also rhizautoicous). Setae 15-20 mm long, yellow- to red-brown, clockwise-twisted; capsules 3-5 mm long, brown, ± striolate when dry; annulus up to 5 cell layers thick, revoluble or deciduous in fragments; operculum about 1.3 mm high, high-conic, with cells in straight or weakly clockwise-twisted rows; exothecial cells elongate; peristome teeth 300-650 µm long, straight or weakly twisted in a clockwise fashion. Spores 10-13 µm, yellowish, weakly papillose.

    A Mexican report of a sterile collection of T. crassinervis (Hampe) L. Koch needs verification (Bowers, Delgadillo & Sharp, 1976). The monoicous sexuality of T. anomala provides the only certain means of distinguishing it from that species of western North America.
