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
Dioicous, minute, densely tufted saxicolous moss. Tufts yellow-green above, brown below. Stems 5-6 mm tall, simple or sparingly branched, radiculose in the lower part. Leaves up to 2 mm long and 0.3 mm wide at base, crisped when dry, spreading when moist, crowded above, concave, from a widened non-sheathing ligulate base; lamina obtuse or acute, apex usually rounded; margin entire, plane or recurved to one side. Nerve about 60 microns wide at base, narrow and indistinct in the subula, failing well below apex. Cells incrassate or with firm walls, smooth, rather turgid above; those of the subula about 10 microns, usually quadrate, those below shortly rectangular, 2-3 x 1. Perichaetial bracts with much wider base. Seta c.10 mm long, erect and symmetrical, slightly plicate when dry, narrowly elliptic, with a tapered neck, annulate; stomata wanting. Peristome teeth inserted slightly below rim, red, short, c.140 microns long, irregularly divided in the upper portion, smooth, not striolate. Operculum about 1/2 the length of capsule; beak curved. Calyptra hooded, smooth. covering the capsule. Male inflorescence terminal, gemmiform with short bracts.
Fruiting
Unknown
Threats
Not known. This species has been very rarely collected and does seem to be genuinely uncommon if not biologically sparse. Until further locatiosn are discovered an accurate conservation assessment would, at this stage be impractical.
Substrate
Greywacke and schist rock. In exposed places or under forest
