Abstract

The taxonomy of species related to Verrucaria praetermissa is investigated using morphological and molecular data. Verrucaria devensis is closely related to V. praetermissa but distinguished by the darker colour, the thinner and more uneven thallus, and the ITS sequence. This species is based on Leucocarpopsis devensis G. Salisb., which was originally described as the type species of a monotypic genus differing from Verrucaria by the absence of dark pigment. Verrucaria lapidicola is a new species from stones in non-aquatic situations; it is related to V. praetermissa and V. elaeina but differs in the very thin thallus and ITS sequence.
