*1: Madron Moor, 1864,
WC (PNZ) (Paton 1969a: 708). This record is
older than that listed as new for vc1 by Warburg (1962:
365).
*2: Commonmore, 1920,
RWS (TRU) (Paton 1969a:
708).
S. fallax
and S. flexuosum are treated
as distinct species following Daniels & Eddy (1990: 180)
and Hill (in Smith 2004; cf. Hill 1977a). S. fallax subsp. isoviitae is treated
as a synonym of S. fallax for reasons
given by Hill (in Smith 2004: 97).
Only vc1 record (Porkellis Moor) in hollows in wet
heath, in one place with Sphagnum palustre near
Grey Willow bushes. In vc2 recorded in plenty in most valley
mires, in open sites over substrates of wet, acid peat,
forming lawns or carpets or low hummocks, that are often
extensive. Also less extensive in small mires on wet
heathland, in acidic flushes or in wet hollows in heavily
grazed mires. Associates include Odontoschisma sphagni,
Pleurozium
schreberi, Sphagnum
capillifolium, Sphagnum
denticulatum,
Sphagnum papillosum, Calluna vulgaris, Erica tetralix, Juncus acutiflorus, Molinia caerulea, less
often Dicranum
bonjeanii. Apparently tolerant of slight eutrophication
and disturbance in mires. Also in mires or wet heathy areas on
old china-clay workings, with other sphagna. Three records of
it growing well shaded on flushed ground inside old Grey
Willow
carrs (where presumably relict from more open conditions;
associates Sphagnum
palustre, Sphagnum
squarrosum, Sphagnum
subnitens).
One record c.fr.: dehisced: 9.
