A genus of leafy liverworts. D. albicans is a common and easily recognized species, with creeping primary stems from which arise numerous ascending or erect leafy shoots. The leaves are arranged in 2 ranks; each leaf is deeply divided into 2 lobes, the smaller of which is bent back and partly covers the larger, lower lobe, thus giving the appearance of 2 leaves rather than 1. A whitish ‘vein’ consisting of a band of long, narrow, clear cells runs down the middle of each leaf. They are found on a range of non-calcareous substrates: soil, peat, rock, etc.
