Notes     (Last Modified On 10/8/2017)
Calliergonella contains two species of mostly north temperate affinities; only the species given below is present in the Neotropics. Placed in Calliergon by some authors. The genus is characterized by the tufted habit, presence of a hyalodermis, deeply concave, costate, short and double, rarely ecostate, ovate to oblong-ovate leaves, cucullate, obtuse to rounded apex, auriculate base, linear median cells, and enlarged, thin-walled alar cells. Sporophytes not observed in the tropical Andes. This species may be confused with Pleurozium schreberi, but that species is differentiated by the red stems, epidermal cells small and thick-walled, similar to outer cortical cells, and alar cells of the leaf quadrate. See family references: Hedenäs (1992, 2003), Kanda (1976), and Karczmarz (1971).
Calliergonella contiene dos especies asociadas mayormente al Norte Templado; sólo la especie dada abajo está presente en el Neotrópico. Es colocada en Calliergon por algunos autores. El género se caracteriza por el hábito en manojos, presencia de hialodermis, hojas ovadas a oblongo-ovadas, cuculadas, profundamente cóncavas, costadas, costa corta y doble, raramente ecostadas, ápice obtuso a redondeado, base auriculada, células mediales lineares, y células alares grandes, de paredes delgadas. Esporofitos no observados en los Andes Tropicales. Esta especie se puede confundir con Pleurozium schreberi, pero esta última se diferencia por los tallos rojos, células epidermales pequeñas y de paredes gruesas, similares a las células corticales externas, y células alares de la hoja cuadradas.
