Grows as dense pure cushions that may extend for 5
cm or more, but as sparse patches of low plants when becoming
established. Notes on habitats in Cornwall are as follows. A
calciphile with few records, although locally quite well
established and plentiful at two of its sites. Gwennap: plenty
on damp vertical mortared-stone retaining wall above stream,
partly to fully shaded by trees. Crenver Grove: on soil in
crevices of old mortared-stone wall, part shaded (associates
included Cephaloziella
calyculata). Crow's Nest: forming substantial cushions in
crevices of old, mortared-stone retaining wall facing east on
old mining ground, partly shaded by Gorse
bushes.
