- 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.

Indigenous. North, South and Stewart Islands.
Plants usually occurring as isolated stems admixed with other bryophytes, more rarely as discrete plants. Stems mostly unbranched, to 7 mm. long, 0·2 mm. thick, flagella mostly one on each stem, usually short, with minute, distant, retuse or entire leaves, becoming smaller and more distant towards the apex. Leaves ovate-triangular, squarrose or with the upwards part of the leaf curved upwards, or even hamate, transverse attachment, 0·6 mm. long. 0·4 mm. wide at the widest part, concave, apices variable. obtuse or bluntly acute, shortly bifid with divergent lobes or curiously curved backwards towards the ventral margin. Cells 30–40 micrometre, still larger in the basal part, walls sinuous to stellate, caused by the very large trigones with bulging sides. Stipules, the width of the stem or a little more, 0·3 mm. tall, ovate-rotund, mostly entire, rarely very shortly bifid, more regular in shape than the leaves. Perianth 3·5 mm. long, 0·5 mm. broad at the base, narrowed to the apex, mouth piliferous, hair-points to 0·3 mm. long, crooked and entangled, a little toothed and in one instance branched. Seta as long as the perianth. Innermost pair of involucral leaves reaching almost 1/3 up the perianth, with narrow apices, shortly bifid reflexed. Second pair reaching half-way tip the innermost, with similar apices.
Although fruit has been seen insufficient information exists to provide any details on the timing of fruiting
Known from very few recent sites and at most of these it is seriously threatened by coal mining
Terricolous on silt, sand and peaty ground. In the coal country of the western South Island it is found either partially submerged in streams or on the surrounding dripping wet, deeply incised, canyon like walls
