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.

2009 | At Risk – Naturally Uncommon | Qualifiers: RR, Sp
Distribution
Indigenous. New Zealand: North and South Islands. Also China, Japan, Central Asia, Europe, Greenland, Iceland, and North America
Habitat
Terricolous on moist rocks in montane forest and subalpine scrub.
Features
Plants small to medium-sized, up to 35 mm tall, dark green or yellowish brown, in dense tufts. Stems erect, simple or forked, radiculose below. Leaves strongly curled and contorted when dry, narrowly oblong- to linear-lanceolate; margins irregularly and narrowly recurved below, entire or indistinctly sinuate above; costa single, strong, ending near the leaf apex, papillose on both sides; upper laminal cells rounded-hexagonal, 8–10 µm in diameter, thick-walled, very opaque, densely warty-papillose; lower cells slightly larger, rectangular, thin-walled, hyaline or pale yellowish, smooth; alar cells not differentiated. Autoicous. Perichaetial leaves greatly enlarged, entirely sheathing, broad at base, short-pointed at the apex. Setae up to 2 mm long, as long as or shorter than perichaetial leaves; capsules shortly emergent, 1.0–1.3 mm long. Spores 9–12 µm in diameter, usually smooth or nearly so.
Fruiting
Fruiting material is known from New Zealand but there are insufficient gatherings as yet to determine periodicity
Threats
Amphidium lapponicum is known from very few sites, all of which are located within protected land. There are no known threats. For this reason Amphidium has been listed as “Naturally Uncommon” (see Glenny et al. 2011).
