Habitat notes from C&S are as follows. Grows
mainly on acidic, damp to wet, humic or peaty soils.
Apparently intolerant of shading and absent from tall heath
vegetation. On heathy cliff slopes, by flushes above cliffs,
on coastal heaths, in short areas of wet heathland inland and
on hummocks at edges of mires. Close associates often include
Campylopus
introflexus, Erica spp. Paton
(1969: 718) noted that a stunted form occurs amongst turf on
dry heathy cliff tops; DTH has seen this in the Isles of
Scilly.
Not seen c.fr. [Dioicous; capsules being very rare
in British Is.; unrecorded in Cornwall].
