*1: Trencrom Hill,
1880, EDM (BM) (Paton 1969a: 716). [Earlier
report (W. Cornwall, in Curnow & Ralfs 1882) not supported
by specimen: Paton 1969a: 716].
*2: Damp bank of waste
from china-clay workings, Hendra Downs, Nanpean, Feb. 1962,
JAP (BBSUK) (Warburg 1963b: 494, Paton 1969a:
Easily overlooked among other small Dicranales with
narrow leaves. When lacking capsules perhaps inseparable from
heteromallum with which it often grows, so probably
under-recorded. When capsules are present it is distinct in
the rostrate lid and peristome type.
Grows on partly bare banks, track edges and flat
ground with substrates of clay or gravelly clay near old and
working china clay quarries, almost or quite unshaded; often
in wet or damp places. Also a bit intermixed with Ditrichum heteromallum
on soft crumbling granite on vertical face of large boulder
inside working china clay quarry.
Commonly (frequently ?) c.fr.: Capsules immature 3,
dehiscing 3, dehisced 3.
