*1: On ground in woodland of Quercus petraea on
S.-facing hillslope, S. of Gweek SW72, 1995, DTH 95-52 (BBSUK, DTH) (Blockeel
1996: 45).
*2: On ground under oak forest in old deer park,
Boconnoc Park, 1971, FRo (BBSUK) (Crundwell
1972a: 1973: 508).
L.
glaucum and L. juniperoideum were
not usually separated in Britain until the
study by Crundwell (1972); older records are placed as L. glaucum s. l. unless specimens
have been revised subsequently.
Usually pure, flat patches which grow to become
domed and eventually rounded cushions up to ca 30 cm across. Grows
on acidic often humic soil, edges of granitic or slaty rocks
and on well-rotted decorticated wood of fallen branches, logs
or stumps. Closely associated with deciduous or coniferous
woodlands (often Sessile Oakwoods), or at least groves of
trees (seen once in young plantation of Beech), growing in
light to moderate shade, often on slopes such as steep edges
of ditch banks and edges of rocks. Associates include Leucobryum glaucum,
but it commonly replaces that species in woodland
habitats.
Not seen c.fr. [one JAP record from vc2]. See
Blackstock (1987) for notes on ecology and sexual
reproduction.
