Description: Long-lived wintergreen moss, forming a dense turf (mat-like), blackish-green above, reddish-brown below. Stems to 1 cm (0.4 in.) in length, branching occasionally. Stem leaves spirally twisted, appressed to weakly spreading when dry, 0.6 - 1.0 mm (0.04 in.) long,
margins broadly recurved to revolute to the apex of the leaf. Leaf apex cucullate (shaped like a hood). Costa is percurrent (reaching to the apex but not beyond). Rhizoids few, arising from leaf axils. Asexual
reproduction by rhizoidal tubers or axillary gemmae (vegetative diaspore that can germinate to form a new plant that is genetically identical to the parent plant). Male plants are unknown to science.
Habitat: Restricted to gypsum pockets and outcrops, on east to north facing slopes of loose soil, often associated with other moss species. Elevations: 400 - 706 m (1,312 - 2,316 ft).
Range: Known from vicinity of Gold Butte, Clark County, Nevada. Also known from British Columbia, Texas and Mexico. This species is scattered in distribution in gypsum pockets of southern Nevada and southern Utah, with one potential location in southern Colorado.
Comments: Type specimen collected by Gayle Marrs-Smith in 1994. This species can be identified by its twisted leaves when seen under a magnifying lens, along with the lime green coloration when wet, tan
coloration when dry, and the distinct cucullate leaf apex.
