Habitat notes from C&S are as follows. Common
on soil just above water of streams, ditches, river banks
(also a canal bank and lake bank), in flood-zone and a little
above it, almost unshaded to rather heavily shaded by
deciduous trees. Often on silted rocks in and at edges of
streams. Soil on banks and slopes near streams and well away
from them, e.g. on field edges under trees, on quarried slope
under trees, laneside and trackside banks, in old quarries, in
churchyards, cemeteries, in sheltered places in gardens, in
shelter under scrub on slope above sea-cliff, floor of damp
Grey Willow carr, on damp soil on flushed sea-cliff.

pusilla, Homalia
trichomanoides, Nardia scalaris, Pellia endiviifolia,
Pellia epiphylla,
Phaeoceros laevis,
Pohlia annotina, Thamnobryum
alopecurum.
Also on soil on tops, ledges and at bases of walls,
low on 'hedges', and in crevices of masonry, but generally in
humid and sheltered or partly shaded places, e.g. about old
mill, on and inside ruins, near ruined buildings on old mine
spoil (with Barbula
convoluta), in moss carpet on open area of old copper-mine
spoil, on soil well shaded under overhanging concrete of ruin
of mine building, on bank in cemetery, on old decayed mortar
in partly shaded wall, on a gravelly lay-by. Locally plentiful
on unshaded sandy soil over old mine-spoil in and beside
trackways in sand-dunes at Upton Towans and near Godrevy
(occasionally mixed with Petalophyllum
ralfsii). Large patches on vertical masonry of side of
mill race in spray from 'waterfall'; growing 2-3 cm out from
substrate here, in contrast to usual almost flat mats. Twice
seen as patches on thin film of clay and old concrete of walls
of ruins; lightly to moderately shaded. Patch on vertical
stone at base of wall. Thin soil low on wall, part shaded.
Soil on area of old china clay spoil, but closely associated
with small patch of calcareous masonry debris and not in
acidic areas around; unshaded. Partly bare, part shaded,
horizontal soil under Grey Willows on old mining ground (with
Oxyrrhynchium
hians, Oxyrrhynchium
pumilum).
All but very young plants nearly always with
gemmae. Not seen
