Conservation status of New Zealand indigenous vascular plants, 2012
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2012 using the New Zealand Threat Classification System (NZTCS). This report includes a statistical summary and brief notes on changes since 2009 and replaces all previous NZTCS lists for vascular plants. Authors: Peter J. de Lange, Jeremy R. Rolfe, Paul D.

Features

Autoicous, glaucous-green, shortly-tufted moss. Stems 6-7 mm long, tufted, branched. Leaves numerous, rather dense toward stem tips, spreading, slightly curled, when dry, scarcely sheathing from a narrowly ovate base; lamina lanceolate, acuminate; margins recurved, finely serrulate; nerve distinct, excurrent, conspicuously broad, occupying c.1/3 of width of sheath up to the middle of the subula; exposed portion of nerve on underside of leaf finely papillate, rugose; subula denticulate especially above, toward the apex; lower cells elongate, upper quadrate, clear, incrassate to papillose, 7-11 microns long, more or less isodiametrical; perichaetial broader. Seta up to 10 mm long, red; operculum convex, apiculate.

Fruiting

Fruits have been observed but insufficient specimens have been seen to determine the main fruiting period.

Threats

Seemingly very uncommon and known from only one recent gathering (1980s) gathering. Probably better assessed as Data Deficient.
