Often forms extensive patches, commonly of this species alone. Rather uncommon in Isles of Scilly. Habitat notes from C&S are as follows. On acidic rocks (mainly steep faces) and steep acidic soil in old quarries (granite, slate), on banks in woodland (deciduous and conifer), banks beside tracks, lanes and roads, stream banks, bank at edge of reservoir, banks on heaths and in acidic flushes, upper slopes of sea-cliffs, low cliffs beside creeks, groves of trees and other banks, on 'hedges', soil on top of stone walls, boulders beside reservoir and in areas of old copper mine spoil. Commonly in light to moderate shade, but sometimes in open, or sometimes heavily shaded (e.g. on rock in entrance to old mine adit) or trickling with water. Common on old metalliferous mine spoil on flat ground, gentle slopes or steep banks, often as extensive patches, sometimes in places that are apparently copper contaminated, often partly shaded by Calluna vulgaris or on N.-facing banks (near Gymnocolea inflata). Also common in crevices of walls built of or retaining mine spoil. On old walls, usually slightly to rather heavily shaded, on rock or thin soil (with e.g. Campylopus flexuosus, Dicranum scoparium, Lophozia ventricosa). On clay and stony soil of flat areas and banks, and on sheltered sides of granitic boulders in old china clay quarries and as colonist on banks in and around working quarries and on spoil heaps, often in large patches (with Cephalozia bicuspidata, Gymnocolea inflata, Nardia scalaris). Acidic soil and wet humus on banks and slopes on and above sea-cliffs. Peat and humic soil of banks on heaths and wet heaths, in mires and beside acidic flushes, locally on moribund sphagna (with Calypogeia arguta, Cephalozia bicuspidata, Scapania irrigua). Other associates include Calypogeia fissa, Calypogeia muelleriana, Cephaloziella hampeana, Dicranella heteromalla, Entosthodon obtusus, Kindbergia praelonga, Heterocladium heteropterum var. heteropterum, Isothecium myosuroides var. myosuroides, Solenostoma gracillimum, Lepidozia reptans, Lophozia bicrenata, Pellia epiphylla, Pogonatum aloides, Pohlia annotina, Pseudotaxiphyllum elegans, Scapania compacta, once each Ditrichum plumbicola, Lophozia sudetica, Tetraphis pellucida.

 

Foliar gemmae very common. Perianths common: 1-4, 6-12; capsules occasional/frequent: immature 1-4, dehiscing 2, 3; dehisced 2, 3.
