*2: Tree on bank of R. Tamar, S. of Launceston, 1961,
JAP (BBSUK) (Warburg 1966: 201, Paton
1969a: 743).
Transfer of this species to the genus Dendrocryphaea follows
the revision by Rao (2001: 103).
Grows as small to larger patches (maximum 50 x 30
cm). Young plants grow closely appressed to bark; older taller
plants rather stiffly arcuate when dry, but trailing when wet.
Notes on its habitat in Cornwall are as follows. Restricted to
bark of trees (trunk bases, branch bases, exposed roots)
within lower parts of flood-zone of R. Tamar (mainly from
0.5-2.5 m (to 3 m) above summer water-level), growing on
nearly horizontal to vertical or overhanging surfaces, mainly
in light to moderate shade (also almost unshaded). Commonest
phorophytes are Sycamore, Ash and Alder; fewer records on
Hazel; one each on Pedunculate Oak, an epiphytic stem of Ivy
and dead driftwood trunk of Ash. Its patches are often pure,
and it may colonise bark otherwise bare of bryophytes, but
also occurs on substrates with complete cover of epiphytic
bryophytes. Recorded associates are Amblystegium serpens
var. serpens, Sciuro-hypnum
plumosum, Bryum
capillare,
Cinclidotus fontinaloides (in lower sites), Didymodon insulanus, Kindbergia
praelonga,
Frullania dilatata,
Hedera hibernica (sparse), Homalia
trichomanoides,
Hypnum cupressiforme var. resupinatum, Lejeunea
lamacerina, Leskea
polycarpa,
Metzgeria furcata,
Neckera pumila,
Radula complanata,
Syntrichia latifolia, Ulota phyllantha, Zygodon viridissimus
var.
viridissimus.
Commonly c.fr. Capsules immature 1, 3, 5 [nearly
mature, more so than those of Cryphaea heteromalla
growing close by]; dehisced [1, 3, 5 old].
