Schistostegaceae Schimper

Judith A. Harpel

Plants small. Stems erect, arising from a persistent protonema that reflects light, giving off a greenish golden color. Leaves of sterile shoots distichous-complanate. Specialized asexual structures sometimes present, developing on the protonema. Sexual condition apparently dioicous, though male and female plants develop on the same protonemal mat; perichaetial leaves linear-lanceolate, acute, clustered distally on naked stem. Seta straight, smooth. Capsule with peristome lacking. Operculum plano-convex. Calyptra conic-mitrate. Spores, sticky, elliptic.

Genera 1, species 1 (1 in the flora): Circumboreal, uncommon or rare in North America.
