Notas:
The erect, complanate-foliate plants with plane, weakly bordered leaves with a toothed margin, short, single costa that is forked distally, and the distinctive distally ciliate seta are diagnostic for the genus. Calyptrochaeta is a pantropical genus of fewer than 30 species; about 3-5 species in the Neotropics. Rare from mid to high montane forest in the tropical Andes; on rock, and possibly epiphytic. The name Eriopus Brid., nom. illeg., was employed previously by authors. Piloseriopus Sharp is a synonym of Calyptrochaeta.
 
Son diagnóstico para el género las plantas erectas, complanado foliadas con hojas planas, débilmente bordeadas, con un margen dentado, costa corta , simple bifurcada distalmente, y la distintiva seta ciliada distalmente. Calyptrochaeta es un género pantropical de menos de 30 especies; alrededor de cinco especies en el Neotrópico. Raro desde bosques montanos medios a altos en los andes tropicales; sobre rocas y posiblemente epífito. El nombre Eriopus Brid., nom. illeg., fue empleado por autores previos. Piloseriopus Sharp es un sinónimo de Calyptrochaeta.
 
The status of the following species is unknown; no combination is made since there is a high probability that it is a synonym of an earlier name from the tropical Andes (or Neotropics): Eriopus papillatus Herzog, Beih. Bot. Centralbl. 26(2): 80. 1909. Type: Bolivia. Auf faulem Holz im Bergurwald bei Incacorral (Prov. Cochabamba), ca. 2200 m, Jan 1908, Herzog s.n. Herzog (1916) cited additional collections from Bolivia, ranging in elevation to 2800 m.

Plants medium sized, forming short lax tufts or mats, glossy pale green. Stems suberect, in cross-section central strand absent. Leaves loosely complanate, differentiated between asymmetric lateral and ± symmetric, somewhat smaller median leaves, erect-spreading, broadly oblanceolate or obovate, apex short to rather long acuminate, base slightly decurrent on lateral leaves; margins plane, limbate, sharply serrate; costae single 1/2 or less lamina length, forked along nerve, unequal, on some leaves indistinct or absent; laminal cells smooth, median cells broadly to narrowly hexagonal; marginal cells forming a border, 1-4 rows of linear cells. Autoicous or dioicous. Perichaetia lateral; leaves small, ovate-lanceolate. Setae elongate, rather stout, spinose to ciliate distally with multicellular hairs. Capsules pendulous, urn ovoid to subglobose with a distinct neck; opercula conic-rostrate, erect; peristome double, exostome teeth 16, furrowed, lamellae extending beyond margin; endostome basal membrane high, segments 16, narrow, keeled and perforate, lightly papillose, cilia reduced. Calyptrae mitrate, smooth? or roughed, fringed at base. Spores not observed.

 

Plantas medianas, formando manojos o matas cortas y laxas, de color verde pálido, brillante. Tallos suberectos, en corte transversal sin cordón central. Hojas laxamente complanadas, diferenciadas entre laterales asimétricas y mediales  ± simétricas, menores, erecto-extendidas, anchamente oblongo-lancoladas u obovadas, ápices cortos a bastante largo-acuminados, hojas laterales con bases escasamente decurrentes; márgenes planos, con costa, claramente serrados; costa simple ocupando 1/2 o menos de la longitud de la lámina, bifurcadas a lo largo del nervio, desiguales, en algunas hojas poco distinguibles o ausentes; células de la lámina lisas, células mediales anchamente hasta angostamente hexagonales; células del margen formando un borde, 1-4 filas de células lineales. Autoicas o dioicas. Periquecios laterales; hojas pequeñas, ovado-lanceoladas. Setas alargadas, bastante robustas, distalmente espinosas hasta ciliadas con pelos multicelulares. Cápsulas péndulas, urna ovoide a subglobosa con cuello conspicuo; opérculo cónico-rostrado, erecto; peristoma doble, exostoma con 16 dientes, acanalados, lamelas extendiéndose fuera del margen; membrana basal endostoma alta, con 16 segmentos, angostos, carinados y perforados, finamente papilosos, cilios reducidos. Caliptra mitrada, lisa? o rugosa, con flecos en la base. Esporas no observadas.
