Aulacomnium androgynum (Hedwig) Schwägrichen

Family: Aulacomniaceae

Status: Native

Synonyms:
Bryum androgynum Hedwig

Aulacomnium androgynum is a striking species. The gemmae stalks originating from the apices of stems and topped with tight spherical clusters of football-shaped gemmae are usually visible with the naked eye. Under the microscope, the leaves are equally impressive with large teeth at the apex. The laminal cells each have a single, large, centrally located papilla. The stem is pentagonal in cross section. The leaves are rounded to the origins at the stem and the basal cells are not differentiated (unlike A. palustre, which is much more common in New Mexico). We found A. androgynum on lava rock after rappelling down into the entrance of a cave.
