Forms low lawns or small patches. Notes on habitats
in C&S are as follows. Restricted to coastal sites, where
it grows on partly bare horizontal, sloping or vertical soil
(clay, loamy or gravelly), including thin soil over rocks
(several times over slates; once on shale, once on thin soil
on old slag), in unshaded or less often partly shaded places
(e.g. under bushes). Several records from cliffs or coastal
banks above cliffs, one each from edge of a salt-marsh and
from grassland on bank (sea-wall beside river estuary). Some
records were from around HWST level or where subject to
flooding with brackish water at HWST, others were in locations
that receive salt spray. Few associates were recorded, among
them Didymodon
tophaceus (commonly) and Bryum
dichotomum.
Commonly c.fr. [nearly all records were of plants
with capsules]: capsules immature 1, 2, 4; dehiscing 4, 6,
dehisced (4 old).
