Fissidens rigidulus is a robust species with stems 2-6 cm in length, forming dense dark, olive-green colonies. Stems bear 10-80 pairs of slightly overlapping leaves. The leaves are 2-3 mm long and have a very pronounced border of elongated, thick-walled cells on the margins except at the leaf tip. Leaves have the structure typical for the genus Fissidens: a lower folded (double) portion and a dorsal wing.
Widespread in New Zealand on wet rocks in streams, often submerged
