low Elder in ruined building, with Orthotrichum
diaphanum. Carbis

tarmac of paths in churchyards (associates Didymodon nicholsonii,
Bryum dichotomum;
Bryum capillare
nearby). Kilkhampton: small patch on bark of Cotoneaster tree in
unshaded part of churchyard, close to Frullania dilatata, Ulota phyllantha. St
Austell: small patches on vertical bark 2.5 m up on young
Sycamore on lawn in college grounds, only lightly shaded even
in summer (with Frullania dilatata, Orthotrichum
diaphanum). Penscombe: patches on bark of young Ash and
Wych Elm trees, lightly shaded by roadside, near Frullania dilatata, Orthotrichum affine,
Ulota phyllantha.
Seaton: small patch on concrete of low unshaded wall. Gwills:
plentiful as low lawns (large patches to 10 cm across) on old
tarmac of unshaded driveway with other mosses (Bryum capillare, Didymodon
fallax).
Almost always with foliar gemmae. Not seen
