Grows as smooth mats, which sometimes form large
patches. Habitat notes from Cornwall are as follows. Most
records are from more or less basic rock or masonry or thin
soil layers over them (gabbro, granitic, serpentinite, slate;
mortared-stone walls, concrete; on sloping or horizontal
surfaces), less often steep soil on banks; normally on
free-draining substrates but often in rather sheltered and
humid places. It most often grows in partly shaded sites but
also sometimes where more heavily shaded or in the open.
Habitat types occupied include laneside cuttings and banks,
'hedges', on large boulders, rock outcrops, in old quarries,
old walls (e.g. of ruins, around churchyards, of old bridges
and churches, especially their north and east sides) and
concrete near churches (on graves; beside pathways). Also
recorded twice on boulders in the flood-zone of streams (a
habitat more closely associated with the rather similar
looking Scleropodium
cespitans). Associates recorded include Anomodon
viticulosus,
Zygodon viridissimus var. viridissimus,
atypically Sciuro-hypnum
plumosum.
