*1: On bare patch of moist soil at base of Juncus effusus in
small wet pasture, just NE. of St Enoder, 10/85, 1995, DTH
95-240 (BBSUK,
DTH) (Blockeel 1996: 46).
*2: On soil on low bank beside track in clearing,
woodland N. of Tutwell, SX37, 2000, DTH (BBSUK, DTH) (Rothero
2001: 43).
First recognised as British by Warburg (1965a), but
identification presented difficulties until Whitehouse (1973)
described the rhizoidal tubers. This is an inconspicuous
species that is apparently rather rare in Cornwall,
but it has doubtless sometimes been
overlooked.
Grows as scattered stems or forms small low
patches. Recorded from partly bare damp soil and clayey soil
or sediments, in moist unshaded or lightly shaded sites. The
four confirmed records were from a bare patch at base of Juncus effusus in a
small wet pasture, low bank beside damp track in cleared area
of woodland (near R. Tamar), dried pools along an old track
and sediment exposed high in inundation zone beside Stithians
Reservoir. Associates recorded were Juncus effusus, Aphanorrhegma patens,
Kindbergia
praelonga and Pseudephemerum
nitidum.
Only recorded with rhizoidal tubers. Not seen
c.fr., although well grown perichaetial leaves were present on
one gathering (11). Elsewhere in Britain,
sporophytes are occasional to rare, maturing from spring to
autumn (M.J. Wigginton in Hill et al. 1994:
73).
