Grows as compact cushions, which sometimes grow or
coalesce to form patches. Habitat notes from C&S are as
follows. Records are mainly from coastal slopes and hillsides
(within 500 m of sea), but single collections made far inland
at ca 305 m alt. on
Bodmin Moor (DTH 07-474) and at ca 55 m alt. on
Trehunsey Bridge (DTH 07-476). Occurs mainly
on low rocks (exposures and boulders) of granitic,
serpentinite and slate lithologies, on horizontal and sloping
surfaces or in small crevices, where unshaded or lightly
shaded. One gathering was from a boulder just above
water-level in a stream. One record from unshaded serpentinite
in old quarry on heathland inland in Lizard pen. (W. of
Rosuick). One record from stone on top of wall of bridge over
small river, slightly shaded. One record of plenty on old
tarmac of churchyard path. Associates recorded include Frullania dilatata, Grimmia pulvinata;
also near or touching many bryophytes that grow on thin soil
among rocks, e.g. Archidium
alternifolium, Lophozia excisa, Scleropodium touretii,
Trichostomum
brachydontium and rarely Bryum kunzei, Hypnum cupressiforme
var. lacunosum, Tortula wilsonii; also
touching Cladonia
sp., low herbs e.g. Aphanes sp. and
grasses.
