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.

Distribution
Indigenous. New Zealand: North (Port Waikato, Kawhia, Tuhua (Mayor Island)), South (North West Nelson, Castlehill) and Chatham Islands. Cosmopolitan.
Habitat
Saxicolous on water saturated calcareous and ultramafic rocks, in pools of water or on water saturated soil.
Detailed description
Erect or ascending yellowish moss of water saturated ground or growing within springs or on wet calcareous boulders and/or ultramafic substrates. Stems to 30 mm long, radiculose below, paraphyllia scant, rather regularly but not complanately pinnate, with short (up to 7 mm long) slender, flexuose branches. Leaves spreading to suberect, little altered when dry. Stem-leaves c.1 mm long; lamina ovate-cordate from a narrow decurrent base, gradually and finely acuminate; margins plane, rather finely denticulate; nerve of variably length but often contained well into acumen or nearly to apex; branch-leaves similar but smaller, ovate-lanceolate, acuminate. Cells 20-28 microns long and 3-5 x 1, smooth, elliptic-hexagonal to linear-rectangular; wider and subrectangular towards the basal angles, there sometimes enlarged and thin-walled, so as to form clearly decurrent auricles. Fruits not seen.
