Detailed description
Gracile, tufted, terricolous yellow-green moss of open ground. Stems 10-20 mm tall, simple, slightly radiculose below, densely foliate. Leaves 4.0-4.5 mm long suberect, flexuose when dry but neither crisped nor strict; slightly incurved when moist; from a very short deltoid-triangular base gradually narrowed to a linear-subulate subula, with an robust apex; margins throughout narrowly revolute, bistratose above, spinulose-dentate in two or more rows. Nerve 50-60 microns wide, subequal throughout, projecting dorsally, excurrent, serrate on the back towards the apex. Upper cells 7-10 microns long, very shortly rectangular or subquadrate, obscure and papillose; lower cells in the dilated base pale, empty, narrowly linear; those at the angles laxer, forming a small and distinct but not clearly defined alar group; those at the insertion orange-yellow. Fruits not yet seen.
Distribution
Indigenous. North Island, Hawke’s Bay (Havelock North).
Substrate details
Soil in open or sparsely vegetated ground.
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.

Threats
Unknown. This species has been collected only once in 1929 from pasture at Havelock North (Hawke’s Bay) and it has not been seen since though no one has specifically searched for it either (see Glenny et al. 2011).
