*1: Lizard
Downs, 1946, TGT & EFW
(BBSUK) (anon. 1947: 34, Paton 1969a:
747).
Easily confused with forms of D. aduncus, from which
it differs in the shorter, often double costa (double and
extending 30-50% of leaf length or single and 40-65% leaf
length: Hedenäs 1997: 82) and channelled leaf acumen. Also
rather similar to forms of Campylium stellatum
with a short weak costa, but leaves narrower and monoicous nor
dioicous.
Grows on unshaded, damp or wet soil or over rock,
mostly among short vegetation of flushes on unshaded slopes
above sea-cliffs, also in similar situations at edges of
streams and beside a small ditch, all close to coasts.
Associates include other mosses and short grasses. W. of
Rosuick (Lizard pen.) it grew in unshaded wet hollow in old
serpentinite quarry on heath (with Campyliadelphus
elodes). Also recorded in small quantity in upper part of
inundation-zone around Cargenwen
Reservoir.
