Current conservation status
- Conservation status of New Zealand mosses, 2014 (PDF, 583.87 kB)
The conservation status of 109 New Zealand moss taxa was assessed using the New Zealand Threat Classification System (NZTCS). Four taxa and one undescribed entity that were not included in previous assessments have been added to the list. The conservation status of only two taxa has changed in this assessment. A full list is presented, along with a statistical summary and brief notes on the changes. This list replaces all previous NZTCS lists for mosses. Authors: Jeremy R. Rolfe, Allan J. Fife, Jessica E. Beever, Patrick J. Brownsey and Rodney A. Hitchmough.
- Conservation status of New Zealand hornworts and liverworts, 2014 (PDF, 695.44 kB)
The conservation status of the New Zealand hornwort and liverwort flora is reassessed using the New Zealand Threat Classification System (NZTCS). A full list is presented, along with a statistical summary and brief notes on the most important changes. This list replaces all previous NZTCS lists for New Zealand hornworts and liverworts which previously had been part of a generic bryophyte conservation status assessment that included mosses. Authors: Peter J. de Lange, David Glenny, John Braggins, Matt Renner, Matt von Konrat, John Engel, Catherine Reeb and Jeremy Rolfe.

Detailed description
Autoicous, glaucous-green, shortly-tufted moss. Stems 6-7 mm long, tufted, branched. Leaves numerous, rather dense toward stem tips, spreading, slightly curled, when dry, scarcely sheathing from a narrowly ovate base; lamina lanceolate, acuminate; margins recurved, finely serrulate; nerve distinct, excurrent, conspicuously broad, occupying c.1/3 of width of sheath up to the middle of the subula; exposed portion of nerve on underside of leaf finely papillate, rugose; subula denticulate especially above, toward the apex; lower cells elongate, upper quadrate, clear, incrassate to papillose, 7-11 microns long, more or less isodiametrical; perichaetial broader. Seta up to 10 mm long, red; operculum convex, apiculate.
Fruiting
Fruits have been observed but insufficient specimens have been seen to determine the main fruiting period.
Threats
Seemingly very uncommon and known from only one recent gathering (1980s) gathering. Probably better assessed as Data Deficient.
Substrate
Saxicolous on schist rock, montane to alpine
