First vice-county records of A. muticum s. l.
*1: Boscawen Cliff near
Lamorna, 1872, WC (BM) (Paton 1969a: 723).
*2: Bodmin, 1893 and
1897, RVT (B), det. DTH as A. mediterraneum
(Holyoak 2003a: 62) [the same specimens were listed as A. muticum var. minus by Perry 1967:
412, Paton 1969: 723].
Earliest vice-county records confirmed as A. muticum s. str.:
*1: Soil on bank in
shallow quarry, cliffs S. of Cadgwith, Lizard [SW7113], 1962,
JAP 784, det. DTH (E).
*2: Soil on Cornish
hedge above Stanbury Mouth, S. of Bude [SS2013], 1963, JAP 791
apparently differs from this species only in having spinulose
spores (Holyoak 2003a). Hence, only the few records where the
spore ornamentation has been checked are referred to the
segregate spp., the others being retained here as A. muticum s. l., along with
records of plants lacking mature spores.
s. str. has four records in
vc1, three in vc2. Five of these were from compacted soil in
bare areas on or beside footpaths near coast or at edge of
sea-cliffs, two from nearly bare soil of banks just above
sea-cliffs, all sites being unshaded. Associates recorded: Bryum argenteum, Bryum dichotomum, Bryum subapiculatum,
truncata. It was commonly c.fr. (all records cfr):
capsules immature 1, 11, 12.
s. l. was recorded recently
from a bare patch of unshaded soil in short grassland at
gateway into disused bulb field on slope above sea-cliffs
dichotomum, Ceratodon purpureus,
Also on soil of low bank beside track inland, almost unshaded.
Capsules were present at both sites; immature 10-12,
