*1: On old
near-vertical concrete wall of ruins, unshaded and S.-facing,
E. of St Just, SW33, 1994, DTH 94-434 (BBSUK,
DTH) (Blockeel 1996: 47).
*2: On tall, unshaded,
near-vertical wall of mortared stone beside road, Treviscoe,
SW95, 1999, DTH 99-39 (BBSUK, DTH) (Rothero
2000: 58). An old record from vc2 was discounted because no
specimen was traced (Paton 1969a: 744).
Four records from Cornwall have the following
habitat notes. (1) A single substantial patch on
near-vertical, S.-facing, concrete wall of ruin of old
china-clay dry, Leswidden, E. of St Just, vc1. The site is
unshaded and species growing close by in same habitat include
Grimmia
orbicularis, G. pulvinata, Schistidium
crassipilum and Homalothecium
sericeum. These plants are large enough in part to qualify
as var. morensis,
with stems up to 30 mm long and nearly 2 mm wide when dry, but
the most slender stems on the same patch are smaller and might
be classed as var. sciuroides. (2)
Treviscoe: substantial patches on two tall, unshaded, vertical
walls of mortared-stone, one of them at roadside (near Homalothecium
sericeum). (3) Poundstock: piece fallen from unshaded
E.-facing slate roof of Gild House (mediaeval building in
churchyard). (4) Cemetery at St Stephen in Brannel (SW95L), on
concrete block wall. This gathering matches var. morensis in width of
the shoots (ca 1.5
mm) but only a few exceed 20 mm in length (JAP 2877 in
DTH).
