This species was poorly understood before the
revision by Crundwell & Nyholm (1964); older records are
given only where determinations of old specimens have been
revised more recently.
Habitat notes from C&S are as follows. Frequent
records from soil in arable fields, its commonest habitat
(cereal stubbles, brassicas, set-aside), with Barbula convoluta, Barbula
unguiculata, Bryum
dichotomum, Bryum
klinggraeffii,
Bryum rubens,
Dicranella staphylina, Trichodon
cylindricus,
Entosthodon fascicularis, Funaria
hygrometrica,
Phascum cuspidatum,
Pohlia melanodon,
Riccia glauca,
Tortula truncata, rarely Didymodon tomaculosus.
In small quantity on partly bare gravelly soil of roadside
lay-by, almost unshaded, near Barbula convoluta, Barbula unguiculata,
Bryum argenteum, Bryum dichotomum, Dicranella
staphylina,
Trichodon cylindricus, Tortula truncata.
