V. dolosa grows on shaded rocks (siliceous and calcareous) and rock fragments, often those by wooded upland streams. It has a thin, smooth thallus and small spores (13-19 x 6-9ųm [max.]). The spherical discs (perithecia) project upwards and are not immersed. In Ireland, the lichen is only known from County Galway.

Key characteristics

  • Small species with a thin, smooth thallus and small spores
  • The discs are protected above by a conical veil of black tissue called the involucrellum.
