This was described as a species distinct from H. ciliata (Hedw.)
P.Beauv. by Hedenäs (1994). British records of the group were
revised by Crundwell (1995; cf. Blockeel 1996: 47). Although
only H. stellata has been
confirmed in Cornwall,
H. ciliata (Hedw.)
P.Beauv. s. str. might also occur
although if so it must be rare. Older records are listed are
listed as H. ciliata s. l. unless specimens
have been revised more recently.
Grows as patches or mats, less often longer wefts.
Notes on habitats in Cornwall are as follows. On surfaces
mainly of granitic rock (but also gabbro), most often where
horizontal to moderate sloping (less often on vertical
surfaces) with incomplete vegetation cover and unshaded (but
sometimes partly shaded), mainly avoiding very exposed places.
Sites include outcrops such as tors, rocks and boulders in
heathland and on hillsides with acidic grassland, old quarries
and their spoil, rock in 'hedges' and riverside boulders (just
above normal flood-zone). Close associates often include Andreaea rothii, Dicranoweisia cirrata,
heterostichum, lichens; others recorded include Ceratodon
