Habitat notes from C&S are as follows.Growing
in small to large patches on varied acidic to neutral
substrates. Common on rock (granitic, serpentinite, slates, on
horizontal, inclined or vertical surfaces), thin soil over
rock, and on soil (mineral, humic, or peat), locally frequent
as epiphyte on bark of living trees or large shrubs (usually
with other mosses, on e.g. Beech sapling, Grey Willows, Hazel,
Sessile Oak), sometimes also on wet peat and tussocks in mires
and on dead or rotting wood (five records, including timber of
old gates). Commonly both in open sites and in moderately
shaded, sheltered places. Frequent or common habitats include
deciduous woodland and groves, old Grey Willow carrs, rocks
and their crevices (outcrops, boulders, old walls), 'hedges',
gravel on graves, heathland, heathy banks, short acidic
grassland, mires, old quarries, metalliferous mine spoil,
china clay spoil, disused railway tracks, sea-cliffs including
some on exposed coastal headlands. Occurs on acidic sand of
dunes in Isles of Scilly. Unusual record of it in plenty on
thatch of roof of Friend's Meeting House at Come-to-Good.
