Habitat notes from Cornwall and the Isles of Scilly are as follows. Colonist on damp often clayey soil on ground recently made bare, and on damp track edges, banks near canal, beside track and beside a path, unshaded or lightly or partly shaded e.g. by woodland or scrub (near Atrichum tenellum, Dicranella heteromalla, Fossombronia pusilla, Pleuridium subulatum, Pseudephemerum nitidum, Riccia subbifurca). Damp soil in gardens, unshaded to lightly or part shaded. In damp stubble fields, fallow arable, flax stubble (once in horticulture) (with Anthoceros punctatus, Barbula convoluta, Bryum dichotomum, Bryum rubens, Dicranella schreberiana, Dicranella staphylina, Didymodon insulanus, Trichodon cylindricus, Entosthodon fascicularis, Ephemerum minutissimum, Fossombronia pusilla, Tortula truncata, Poa annua, Veronica persica). Mainly bare patches of soil in damp pastures and grass leys (with Anthoceros punctatus, Brachythecium mildeanum, Brachythecium rutabulum, Philonotis caespitosa, Fossombronia pusilla). Near-vertical damp clayey soil of bank under Sycamore trees at edge of pasture. Steep damp soil of lightly shaded bank above stream (with Anthoceros punctatus, Dicranella heteromalla, Fossombronia pusilla, Lunularia cruciata, Nardia scalaris, Pellia epiphylla, Pohlia annotina). Bare disturbed soil patch on laneside bank, part shaded. Colonist on bare patches amongst damp china clay spoil. Abundant on clayey spoil-banks among low grasses and in bare patches at edge of china-clay quarry. Few records of sparse patches on mud exposed in inundation zones beside reservoirs, with sparse low vegetation, unshaded (with Trichodon cylindricus).

 

Antheridia seen 1, 3-7, 10-12; capsules immature 1-7, 11; dehiscing 5, 6.
