Habitat notes from C&S are as follows. In
compact patches on soil (mineral, humic or peaty, usually
acidic) or thin soil over rock. Often common in unshaded sites
on or near coasts, but occasional to frequent also inland
where it more often occurs in moderately to rather heavily
shaded places under trees, as well as in unshaded places.
Commonest on sea-cliffs (often in exposed places), coastal
slopes, banks, 'hedges' or quarries on and above cliffs and
coastal heaths. Records inland from heaths, in old quarries,
heathy areas on old mine-spoil, on bank of china-clay spoil, a
churchyard bank, on graves, 'hedges', a laneside bank, crag in
scrub, in young conifer plantations, banks in mature deciduous
woodland and groves of trees (including tall Beeches). Unusual
records from old unshaded tree stump in cemetery and on soil
of plant pot in nursery garden. Numerous associates, among
those that are common are Campylopus
introflexus, Hypnum
jutlandicum, Scapania compacta, Weissia
controversa.
Reproduces vegetatively from abundant caducous
leaves. Four records c.fr. (in vc1); capsules immature 2, 4, 11;
dehisced 10.
