Apparently rare in Cornwall, and often reported in
error by bryologists from 'up country' who regard it as a
common plant that does not need close
examination!
Habitat notes from Cornwall are as follows. Grows
in small patches, or mixed with other bryophytes. On concrete
and mortar of ruins of walls and buildings near china clay
quarries; unshaded. On granitic rock partly shaded by saplings
at edge of disused area of granite quarry. On steep slaty rock
of laneside bank, almost unshaded.
Four records c.fr. (vc1): capsules immature 1, 3,
11, 12; dehiscing 3, dehisced 2.
