Not generally recognised in Britain until the
revision by Lewis & Smith (1978).
Grows as scattered stems, sometimes mixed with
other low bryophytes, or forms small low patches. Notes on
habitats in Cornwall are as follows. It is usually found as a
colonist on damp or wet acidic substrates, including clayey,
loamy, gritty and gravelly soils and firm clay or peaty mud
beside reservoirs. Its sites were mainly unshaded,
occasionally lightly shaded. Most records were from damp edges
of marshes, near streams, small pools, or on wet flushed
ground (commonly on tops of earthy ridges or hummocks of
cattle-poached areas, often near Juncus). Others were
from a damp heathland track, other wet tracks, a path in the
grassy edge of heathland, a stream bank, high in inundation
zones beside reservoirs and in old china clay workings (e.g.
near pools and on tracks). One record was from the edge of an
arable (barley) field. Recorded associates were Archidium
alternifolium,
Atrichum undulatum,
Bryum dichotomum,
Bryum bornholmense,
Ceratodon purpureus, Dicranella
rufescens,
Trichodon cylindricus, Ephemerum serratum, Fossombronia
wondraczekii,
Leptobryum pyriforme, Pohlia annotina, Pseudephemerum
nitidum, Tortula
truncata, Juncus
bufonius, J. effusus, Lythrum portula, Montia
fontana.
'Always' with axillary bulbils, which are usually
plentiful. Not seen c.fr. (sporophytes are unknown in
Britain according
to M.J. Wigginton in Hill et al. 1994:
69).
