Grows in patches that may be extensive, or
scattered amongst other mosses. Habitat notes from C&S are
as follows. Often plentiful on gritty or compressed soil on
and beside tracks, on trampled pathways, on banks and among
rocks in old granite quarries; unshaded.
In small crevice of vertical granitic rock of wall
of old quarry. On thin soil on unshaded top of granitic
boulder. Damp clayey soil of edges of tracks around working
and disused china clay quarries, unshaded; wet, disturbed
ground among china clay spoil and beside tracks near spoil
heaps (close to Archidium
alternifolium, Aulacomnium
palustre,
Philonotis fontana). Patches on inclined surface of
flushed granitic rocks on upper and lower parts of sea-cliffs
and on slope above coast, unshaded. On damp path high on
cliffs. Wet stony pathway on heath over gabbro. Very short
vegetation at edge of acidic flush beside mire. On slaty rock
in open acidic flush and locally on soil of low hummocks and a
bank. Scattered small patches widespread on peaty substrates
exposed in upper part of inundation-zone beside
Colliford
Lake,
always of immature plants. Abundant on damp tarmac at edge of
car park, almost unshaded. Small amount with other mosses on
old tarmac of sheltered lane. Plentiful on tarmac edges of
access road to disused granite quarry, extending over hundreds
of metres; with Bryum
capillare,
Ceratodon purpureus. Other associates recorded include Archidium
alternifolium, Campylopus
introflexus, Pohlia
annotina, Cladonia
