In our area known mainly from Isles of Scilly, but
with single record from vc2 (St Just in Roseland churchyard,
2006, JAP). In Scilly it had become very common and widespread
by 2003, occurring mainly on unshaded or lightly shaded acidic
substrates, especially peaty paths and track edges on coastal
heathland and cliff tops, but also on gravelly paths, among
rocks, in woodland and scrub, at roadsides and in gardens.
Also seen several times on well rotted dead wood of stumps.
JAP noted in April 2003 that it was growing over Fossombronia and Riccia spp., which
were able to hold their own amongst Archidium
alternifolium but unable to compete with the L. semiteres that is
appearing as a new colonist on clifftop and heathland paths in
the Isles of Scilly.
