Often abundant, forming extensive patches with
arching shoots. Habitat notes from C&S are as follows. On
soil and plant-litter of slopes, banks and path-sides in
deciduous woodlands and open conifer plantations (or edges of
denser stands), laneside banks with trees, in open to
moderately shaded, sometimes rather heavily shaded; often
growing over low rocks, tree bases and fallen, dead wood. Also
recorded on ground in churchyards and in open scrub area among
low serpentinite rocks. Base of walls of ruins and sometimes
growing over sheltered old walls, e.g. on old mine-spoil, in
open to well shaded. Bits on soil in short lawn edge, tops of
low walls (beside road, in churchyard), unshaded. On 'hedges'
in open or more often shaded by woodland and scrub. Once in
Grey Willow carr, extending 0.5 m up trunks as epiphyte. One
record from soil of banks high on sea-cliff of apparently
rather base-rich slates (Bossiney Haven). Apparently a
calcicole, or at least absent from more base-poor sites and
common mainly in woods with better soils. In two china clay
areas of predominantly acid soils large patches were
associated with old concrete and not present elsewhere in
vicinity, but a single record in third area from partly
vegetated bank of china-clay spoil with no concrete or
masonry. Also near ruins of mine and other buildings. Common
associates include Atrichum undulatum, Brachythecium
rutabulum, Kindbergia praelonga, Lophocolea bidentata,
Plagiochila
asplenioides, Polytrichastrum
formosum, Thuidium
tamariscinum.
In most regions only occasionally cfr, but
frequently c.fr. in some woods: capsules immature 1, 2, 4,
10-12; dehiscing 1-3, 10, 12; dehisced
1-6.
