Often in large or small pure patches, but
frequently also intermixed with other small bryophytes.
Habitat notes from C&S are as follows. On moist, flat and
more or less steeply inclined acidic soil (clay, loam) of
laneside and other banks, wooded stream- and riversides,
beneath exposed tree roots, ditch banks and path edges in
deciduous and mixed-conifer woodland, groves of trees, scrub
(associates include Calypogeia arguta, Calypogeia fissa, Dicranella
heteromalla, Diplophyllum albicans,
Solenostoma
gracillimum, Lophocolea bidentata,
Mnium hornum, Nardia scalaris, Scapania nemorea,
rarely Fissidens
polyphyllus), similar habitats near stream in wet
pastures, almost unshaded to part
shaded.
Often plentiful on moist clay and other substrates
of steep and gently sloping banks in old and newer china clay
quarries, unshaded and part shaded. Clayey banks in old
quarried area, unshaded (near Pogonatum aloides).
Damp slaty rock surface in part-shaded entrance to old mine
adit. Walls and banks by old mine shafts. Locally on old
copper-mine spoil, e.g. at base of sparse Calluna vulgaris (with
Diplophyllum
albicans), and in wet area near Juncus effusus. Damp
humic soil of steep streambank in old mine area, N.-facing but
unshaded. Acid soil of vertical path-side banks, part-shaded
only (with Calypogeia
fissa, Pellia
epiphylla). Soil in crevice of 'hedge'. Soil and damp
humus of banks above sea-cliffs and in cliff-top flushes,
unshaded to part shaded. On damp sand, peaty or humic banks,
decaying tussocks, and among living or moribund sphagna on
heaths and in mires (associates recorded include Calypogeia fissa, Calypogeia
muelleriana, Cephalozia connivens,
Dicranella
heteromalla, Mylia
anomala, Riccardia
chamedryfolia, Riccardia latifrons,
Sphagnum
subnitens). On decayed Pteridium aquilinum
humus on bank above path. Peaty soil on flat path edge on
heath. On decaying litter low on Molinia caerulea and
other tussocks and low damp earthy banks in mires and acidic
flushes (with Calypogeia fissa, Calypogeia arguta, Calypogeia
muelleriana, Cephalozia connivens,
Diplophyllum
albicans, Entosthodon obtusus,
Kurzia pauciflora,
Kurzia
trichoclados, Lophozia ventricosa,
Pohlia annotina, Riccardia latifrons),
similar habitats in wet hollows in china clay pits and on
china clay spoil heap (with Atrichum undulatum, Campylopus pyriformis,
Gymnocolea inflata,
Solenostoma
gracillimum, Lophozia incisa Riccardia latifrons,
Riccardia
multifida).
Frequently with gemmae (which are sometimes very
abundant): 1-3. Commonly cper: 1-5, 7-12. Frequently c.fr.:
immature 1-4, dehiscing 3, dehisced 3, 4.
