general taxon notes:

Ecology. Open Yungas montane, to be expected in the puna; on soil. Elevation. 2200 m. Distribution. Bolivia: Cochabamba. World range: widespread in the Northern Hemisphere.

Bryum caespiticium is characterized by the distally crowded, imbricate, ovate-lanceolate (to 3 mm long) leaves, recurved and subentire margins, strong, excurrent costa, elongate and firm-walled cells above, rectangular basal cells, dioicous sexual condition and well developed peristome. This species is likely to be confused with B. pallescens, both are virtually identical gametophytically, the latter however exhibits relatively shorter laminal cells and a short excurrent costa; the monoicous sexual condition (autoicous or synoicous) is the most reliable feature.
Bryum caespiticium se caracteriza por las hojas agregadas distalmente, imbricadas, ovado-lanceoladas (hasta 3 mm de largo), márgenes recurvados y subenteros, costa excurrente, fuerte, células distales alargadas y con paredes firmes, células basales rectangulares, condición sexual dioica y peristoma bien desarrollado. Esta especie puede ser confundida con B. pallescens, ambos son virtualmente idénticas respecto al gametofito; sin embargo, la última presenta las células de la lámina relativamente cortas y costa corto excurrente; la condición sexual monoica (autoica o sinoica) es la característica más confiable.
