BRYOPHYTE NOTES, 1962
139
Fontinalis antipyretica Hedw. var. gracilis (Lindb.) Schp.
From course of old River Lea near Fishers Green at Waltham
Abbey, v.c. 19. An unusual form of this species normally confined
to mountain waterfalls! The River Lea is not dredged where this
is growing and the bed of the river has cut through the overlying
soils down to the gravel, providing a firm base on which the plant
can exist.
Campylum elodes (Spruce) Broth. From side of bomb crater
pond in Hatfield Forest. 28th April 1962, v.c. 19. This is a rare
species from chalky marshland.
Amblystegium serpens (Hedw.) B. & S. var. salinum. Carr.
From Grays chalk pit. February 1959, v.c. 18. A very slender
form, yellowish in colour, with tiny leaves. This is an unusual
habitat as this variety is most commonly found on sandy sea
coasts.
Amblystegium kochii B. & S. From meadow by River Lea
near Waltham Abbey, December 1961, and also by the River Stort
near Harlow Mill. 27th January 1962, both v.c. 19.
Drepanocladus uncinatus (Hedw.) Warnst. From damp con-
crete wall by stream below road level near Margaretting. Although
a common species in Western England it can be considered rare
in our eastern districts.
Liverworts
Fossombronia pusilla (L.) Dum. From Epping Lower Forest
by ditches, 1960, v.c. 19. An overlooked species, the Field Club
has a previous record from this region by the late St. John
Marriott but this had not been officially recorded by the British
Bryological Society.
Fossombronia wondraczekii (Corda) Dum. From sandy ditch
by the Wake Arms, Epping Forest, November 1962, v.c. 18. Both
the above species are identified by the patterns of ridges on the
spores which must be present for correct identification.
Calypogeia muelleriana (Schiffn.) K. Mull. From St. Thomas's
Quarters, Epping Forest, 1962, v.c. 19, and from High Woods,
Ingatestone, 1962, v.c. 18. Although this species is common in
Essex it is being re-recorded as there is confusion between this and
C. trichomanis under which name our old records have been in-
cluded. 0. trichomanis is probably not present in Essex.
Lophozia excisa (Dicks.) Dum. With perianths; from ditch on
Theydon Golf Course, Epping Forest, November 1962, v.c. 18.
Barbilophozia attenuata (Mart.) Loeske. Growing among
Leucobryum glaucum under trees in Monks Wood, Epping Forest,
1st April 1962, v.c. 18.
Chiloscyphus pallescens (Ehrh.) Dum. From ditch in wood-
land by Bailey Hills near Farnham, February 1962, v.c. 19 (with
perianths).
