Only recent vc1 records are from Gear
Sands: several patches on soil of fixed sand-dunes near their
landward edge, in almost bare areas with very short
vegetation. Surrounding vegetation is of NVC type CG, so sand
is doubtless calcareous there. In vc2: several records on
decayed mortar and thin soil of tops, sides and near bases of
old, mortared walls of ruins, especially of mine buildings and
old china-clay dries, where evidently calcareous. Also on old
horizontal concrete. Usually unshaded or almost so, but
moderately shaded by trees nearGolitha
Falls.
Close associates include other small acrocarps, especially Barbula convoluta, Didymodon rigidulus,
Pseudocrossidium
revolutum; also single records of Gymnostomum viridulum,
Lejeunea
patens.
One record c.fr.: capsules immature 10 (numerous
capsules on single patch, N. of Minions, seta short to fully
lengthened).
