Anacolia laevisphaera var. parvifolia Flowers [Bull. Torrey Bot. Club 79: 165. 1952. Anacolia subsessilis var. brevifolia Herzog, Feddes Repert. 45: 47. 1938. Type: Peru. Cordillera Blanca, Gletschervorfeld oberhalb Larger Copachica, 4400 m, 1932, Lucas.]
This variety is only known from the type; apparently a small form and probably not worthy of recognition.

Plants medium sized, forming loose tufts, dark green to yellowish-green, brown below. Stems erect, mostly 2-3 cm tall, few to several branched, subfloral innovations often not conspicuous; in cross-section epidermal cells small and thick-walled, central strand well developed; radiculose below. Leaves loosely erect, tips often spreading, narrowly lanceolate, 3-4 mm long, to 0.5 mm wide, apex narrowly acuminate to subulate; margins reflexed below, recurved above, sharply serrate distally, teeth single or double, becoming dentate below, entire at base; costae single, strong, short excurrent, toothed on back distally; upper and median cells short rectangular, 12-16 µm long, 8-10 µm wide, papillose, papillae at one or both cell ends, occasionally appearing smooth; inner basal cells mostly long rectangular, 40-70 µm long, 6-8 µm wide; alar region undifferentiated, or basal marginal cells quadrate, 8-12 µm in diameter. Dioicous. Perichaetia terminal; leaves little differentiated. [Setae short, ca. equal urn length, smooth. Capsules immersed, erect, urn globose, 2-3 mm in diameter, mouth small; opercula low conic; peristome absent. Calyptrae cucullate. Spores spherical to somewhat ovoid, coarsely papillose].


Plantas medianas, formando manojos laxos, de color verde oscuras hasta verde-amarillento, pardo abajo. Tallos erectos, hasta 2-3 cm de alto, pocas a varias ramificaciones, innovaciones subflorales a menudo no conspicuas; en corte transversal células epidérmicas pequeñas con paredes gruesas, cordón central bien desarrollado; radiculosos abajo. Hojas laxamente erectas, con puntas a menudo patentes, angostamente lanceoladas, 3-4 mm de largo, hasta 0.5 mm de ancho, ápices angostamente acuminados hasta subulados; márgenes revolutos abajo, recurvados hacia arriba, agudamente serrados distalmente, dientes simples o dobles, tornándose dentados abajo, enteros en la base; costa simple, fuerte, corto-excurrente, dentada distalmente en el envés; células superiores y mediales corto-rectangulares, 12-16 µm de largo, 8-10 µm de ancho, papilosas, papilas en uno o ambos extremos, ocasionalmente de apariencia lisa; células basales internas generalmente largo-rectangulares, 40-70 µm de largo, 6-8 µm de ancho; región alar indiferenciada, o células del margen basal cuadradas, 8-12 µm de diámetro. Dioicas. Periquecios terminales; hojas poco diferenciadas. [Setas cortas, aproximadamente igual a la longitud de la urna, lisas. Cápsulas inmersas, erectas, urna globosa, 2-3 mm en de diámetro, boca pequeña; opérculo cónico bajo; peristoma ausente. Caliptra cuculada.
