general taxon notes:
Tayloria contains about 38 species rather widely distributed but concentrated in the highland tropics and subtemperate regions; seven species recorded for the Neotropics. In Bolivia only two species recognized. The genus is characterized by the obovate, spathulate to elliptical or broadly short lanceolate leaves, elimbate, entire to toothed margins, smooth to occasionally papillose setae, cylindrical capsules, rather narrow and short hypophysis, and papillose, 8 or16 toothed peristome.
 
Tayloria contiene unas 38 especies de distribución bastante amplia pero concentradas en las tierras altas de los trópicos y regiones subtempladas; siete especies han sido registradas en el Neotrópico. En Bolivia sólo dos especies son reconocidas. El género se caracteriza por presentar hojas obovadas, espatuladas hasta elíptica o ampliamente corto-lanceoladas, elimbadas, márgenes enteros a dentados, seta lisa a ocasionalmente papilosa, cápsulas cilíndricas, hipófisis bastante angosta y corta, y peristoma papiloso con 8 o16 dientes.

Plants small to medium sized, forming tufts, glossy green to reddish-brown. Stems erect, simple or few branched; in cross-section epidermis small, inner cells large and thin-walled, central strand present; usually tomentose below, rhizoids smooth to papillose. Leaves mostly crispate or contorted when dry, erect-spreading when wet, ovate-short lanceolate, elliptical to obovate or spathulate, apex broadly acuminate, acute or obtuse; margins plane to reflexed below, entire, bluntly serrate or crenulate distally, elimbate; costae single, 3/4 -4/5 lamina length or subpercurrent; upper and median cells large and smooth, hexagonal to rhomboidal; basal cells rectangular, rather lax. Autoicous. Perichaetia terminal; leaves similar to stem leaves. Setae rather short to elongate, twisted or not, smooth or scabrous. Capsules emergent to long exserted, erect, dark red to reddish-black, urn short cylindrical; exothecial cells oblate, thick-walled; hypophysis short (usually equal to or shorter than urn), cells elongate, thin-walled; stomata in distal half, superficial; opercula not observed; peristome single, teeth 8 or 16, papillose, reflexed when dry. Calyptrae not observed. Spores spherical, appearing smooth to lightly papillose.
 
Plantas pequeñas a medianas, formando manojos, verde brillantes a pardo-rojizas. Tallos erectos, simples o poco ramificados; en corte transversal epidermis pequeña, células internas grandes y con paredes delgadas, banda central presente; generalmente tomentosos abajo, rizoides lisos a papilosos. Hojas generalmente crispas o contortas en seco, erecto-extendidas en húmedo, corto-ovado lanceoladas, elípticas hasta obovadas o espatuladas, ápices ampliamente acuminados, agudos u obtusos; márgenes planos a reflexos abajo, distalmente enteros, obtusamente serrados o crenulado, elimbados; costa simple, ocupando 3/4 -4/5 de la longitud de la lámina o subpercurrente; células superiores y mediales grandes y lisas, hexagonales hasta rómbicas; células basales rectangulares, bastante laxas. Autoicas. Periquecios terminales; hojas similares a las hojas del tallo. Setas bastante cortas hasta alargadas, torcidas o no, lisas o escabrosas. Cápsulas emergentes a largo-excertas, erectas, rojo oscuro a negro-rojizo, urna corta cilíndrica; células exoteciales oblatas, con paredes gruesas; hipófisis corta (generalmente igual o más corta que la urna), células alargadas, con paredes delgadas; estomas en la mitad distal, superficiales; opérculo no observado; peristoma simple, con 8 o 16 dientes, papilosos, reflexos en seco. Caliptra no observada. Esporas esféricas, de apariencia lisa a finamente papilosa.
