A rhizomatous, deciduous fern found on mildly acidic to base-rich soils in open woodland, meadows and damp pastures, and on sand dunes, under Pteridium on heaths, and on peat in regularly mown fen. 0-660 m (Burnhope Seat, Cumberland).
O. vulgatum is an inconspicuous species which is very much better recorded than in the 1962 Atlas. It has been lost from many lowland sites where the intensification of agriculture, grazing and drainage have contributed to its decline.
Circumpolar Temperate element, with a disjunct distribution.
