This aquatic, crustose lichen is a familiar sight on permanently submerged bedrock, boulders or stones in streams, rivers and loughs. The thin, blackish thallus is sprinkled with low, cone-like projections: the spherical discs (perithecia). Examination of the spores show them to be small (about 9 x 6/7ųm), simple (without partitions) and broadly ellipsoid. The similar V. rheitrophila is black-flecked, the freckles lying like bits of shrapnel in the body of the thallus. Thinly scattered in Ireland.
