Bryum richardsii is related to B. andicola; both species exhibit leaves that are distally crowded and forming a rosette, leafy innovation branches, excurrent leaf costa, margins recurved below and distinctly bordered, and laminal cells porose. The distinctive feature of B. richardsii is the deciduous flagellate innovation branches; other features include the oblong-obovate leaves to 3.5 mm long, weakly decurrent base, tapered costa, 2-3 rows of long linear border cells. Bryum andicola lacks the flagellate branches, the leaves range from spathulate to oblong-obovate, costa strong, and the border consisting of up to 5 rows of thick-walled cells.
Bryum richardsii está relacionado con B. andicola; ambas especies presentan hojas agregadas distalmente y formando una roseta, ramas de las innovaciones foliosas, costa de la hoja excurrente, márgenes recurvados en la porción basal y conspicuamente bordeados y células de la lámina porosas. La característica distintiva de B. richardsii es la presencia de ramas de las innovaciones flageladas deciduas; otras características incluyen las hojas oblongo-obovadas hasta 3.5 mm de largo, bases débilmente decurrentes, costa estrecha, borde con 2-3 filas de células largas lineares. Bryum andicola carece de ramas flageladas, las hojas van de espatuladas a oblongo-obovadas, costa fuerte y el borde está formado por más de 5 filas células con paredes gruesas.
