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.

Distribution
Indigenous. New Zealand: Kermadec Islands (Raoul Island only)
Habitat
Saxicolous on andesite rock and associated saprolite within ravine systems prone to sudden flash flooding.
Threats
Known only from two gatherings made from Raoul island in 2009 and 2011. There are two populations, neither large. This moss seems to be genuinely scarce on Raoul Island and it will probably warrant listing as Nationally Critical when the Bryophytes are next up for threat listing. Both populations are at risk from flooding, and possibly accidental loss through track maintenance
Substrate
Saxicolous on andesite rock and associated saprolite
Etymology
fissidens: From the Latin fissio ‘fission’ and dens ‘tooth, prong’ meaning split tooth and referring to shape of the lamina.
