Reported for Isles of Scilly (Paton 1969: 734; SV91
in Atlas
3: 74), but perhaps in error since Pohlia lutescens was
not usually recognised at that time and latter sp. has since
been recorded in SW91G.
Grows as scattered plants that may be mixed with
other small bryophytes, sometimes forming low lawns or denser
pure patches. Habitat notes from ornwall are as follows. On
basic to circumneutral (or weakly acidic?) loamy, clayey,
silty or sandy mineral soil, on firm sand or consolidated
sand-rock, where moist or wet, mainly in partly shaded or
sheltered places, or on N.-facing slopes but sometimes in open
sunny places. Occurs on steep soil of banks of streams or
rivers (often abundant and commonly within flood-zones), also
banks beside a canal, ponds and lakes and a reservoir, steep
soil on banks beside roads and lanes, exposed soil in
woodland, Grey Willow carr, beneath Elders on dunes, in
churchyards, a garden, edges of waste-ground, among flushed
granitic rocks, hollows in 'hedges', tracks, path-sides, damp
sea-cliffs and dry mud at a pool edge. Several records from
arable land (barley, maize, stubble, brassicas) in mainly
small amounts (occasionally plentiful) or at field edges.
Occasionally on old, earthy mortar and soil of damp walls and
crevices among old concrete. Common associates include Barbula convoluta, Barbula
unguiculata, Bryum
rubens, Bryum
pallens,
Conocephalum conicum, Dicranella
staphylina,
Dicranella varia,
Didymodon tophaceus, Epipterygium
tozeri, Fissidens
viridulus,
Pseudephemerum nitidum, Tortula truncata,
others recorded include Bryum radiculosum, Bryum violaceum, Dicranella
rufescens,
Didymodon tomaculosus, Fissidens incurvus, Pohlia lutescens, Phascum
cuspidatum.
Tubers have been reported in
British material but they have not been noticed or searched
for in Cornish plants. Only one record c.fr.: single dehisced
capsule: 6 (near Mullion Cove). Large patches with many mature setae but all
capsules aborted: 3 (on stubble field edge W. of
Philleigh).
