*1: On horizontal
concrete of top of wide, old wall of ruined china clay works,
E. of Cold Harbour, SW43, 1995, DTH 95-444 (BBSUK,
DTH) (Blockeel 1997:
43).
*2: On unshaded top of
old concrete wall of ruin of china-clay dry, S. of Treviscoe,
SW95, 1999, DTH 99-38 (BBSUK, DTH) (Rothero
2000: 52).
Six recent records, as follows:
(1) E. of Cold
Harbour: in substantial patches on horizontal concrete of top
of wide old wall of ruined china clay works; unshaded; with Grimmia pulvinata, Schistidium apocarpum
and Orthotrichum
anomalum.
(2) Leswidden: on steep and vertical old
concrete walls of ruins of china clay works; sites S.-facing,
unshaded or almost so; often associated with Grimmia pulvinata. Numerous cushions
here in 2004, along many metres of wall, also several larger
patches up to 17 x 13 cm.
(3) Great Work:
small amounts on small ledge of vertical, S.-facing, concrete
wall of old mine building, unshaded (near Bryum radiculosum, Schistidium
crassipilum, Tortula muralis).
(4)
Treviscoe: unshaded top and steep sides of old concrete walls
of disused china clay dry (no close associates, species nearby
were Tortula
muralis, Grimmia
pulvinata, Schistidium
crassipilum).
(5) SW. of Roche: unshaded top of
mortared-stone wall beside road.
(6) De Lank Quarry: patch on
concrete of ledge low on N.-facing wall of shed (near Schistidium
crassipilum).
Commonly c.fr.: capsules immature 2-4, 12;
dehiscing 2-4, dehisced 4. In April 2003 the population at
Leswidden had many fewer capsules than the accompanying G. pulvinata and most of
those had been damaged, apparently partly eaten (by molluscs
or insects?).
