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.

Distribution
Indigenous. Widespread subantarctic species. In New Zealand known only from Campbell Island.
Detailed description
Autoicous, tufted, saxicolous, blackish-green moss. Stems 5-10 mm tall, branched. Leaves 2.5-3.2 mm long, shorter below, suberect dry or wet, arising from a narrow insertion; lamina narrowly acuminate with blunt apices, bistratose above; margins plane, entire, multistratose below. Nerve usually indistinct above; failing below apex. Upper cells 10 microns, irregularly isodiametrical, smooth; basal cells shortly rectangular. Vaginula with a few short paraphyses, not or only indistinctly ochreate. Seta subsessile. Perichaetial bracts rather long. Capsule 1.50-1.90 mm long, entirely immersed on the subsessile seta; pyriform, coriaceous, exothecial cells strongly incrassate, smooth. Peristome single, rarely with a preperistome; teeth 16, pale, rather coarsely papillose, trabeculate on the ventral surface. Operculum conico-rostellate. Calyptra reddish brown, smooth plicate. Male inflorescence large, terminal at the end of very short branchlets, gemmiform.
Fruiting
Although fruit has been seen insufficient information exists to provide any details on the timing of fruiting
Threats
Not threatened. Within the New Zealand part of its range this species is restricted to a few locations on Campbell Island.
Substrate
Saxicolous on rocks from sea level to alpine zone
