Voitia Systylio,5, plate 1. 1818
w North America, n Eurasia, circumboreal and in mountainous regions.
Species 2 (2 in the flora).
Plants of Voitia are coprophilic, but as they are cleistocarpous, they do not have spores dispersed by flies (order Diptera). Spores are released by the disintegration of the sporangial wall. The dark red capsule is quite distinct, and the two species are easily distinguished by capsule shape. The stems of this genus are often branched; the leaf margins are more or less incurved; the basal laminal cells are 55–95 µm. The perigonia and perichaetia are terminal on separate branches; the setae are yellowish to dark red, darkest distally. The stem leaves are slightly contorted when dry, erect-spreading when moist.
