 Distribution

Cosmopolitan. Tasmania*, mainland Australia*, New Caledonia*, South America*, South Africa*. Also recorded from Europe, Asia, in the neotropics from Mexico to Chile and Argentina (Pursell 2007), and from tropical Africa (Bruggeman-Nannenga 2013). In U.S.A. the species occurs as two disjunct populations, in California and Pennsylvania, according to Pursell (2006). He suggested that the species had been introduced, on two separate occasions, and noted that the California plants “resemble the F. pungens Müll.Hal. & Hampe expression of F. curvatus from Australia”.
Adventive?
 Habitat
A very common and widespread species, on mineral soil, especially as a coloniser after disturbance. Fissidens curvatus is found in mesic to moderately xeric sites, in both indigenous and exotic vegetation, including forest, shrubland, and pasture. Sterile plants, with more numerous, even-sized leaves, commonly grow among fruiting plants. In addition, the species often grows mixed with other species of Fissidens, especially F. tenellus. Even the holotype specimen of F. pungens Müll.Hal. & Hampe is a mixed Fissidens collection. It consists largely of F. taylorii, but a single plant, with a single intact perichaetial leaf, is identifiable as F. pungens, having stout lamina borders that are confluent with the costa at the leaf apex. Achrophyllum quadrifarium, Bryum sauteri and Tortula truncata are other mosses often found in association with F. curvatus.
Recorded from near sea level to 1000 m (Ngāmoko Range, Gisborne L.D.).
