Abstract

Verrucaria madida is described as a new species with a green, subgelatinous thallus, and small ascospores; it is unique in the genus in having 4-spored asci. Three other small-spored freshwater species, V. aquatilis, V. rheitrophila and V. scabra, are compared. The type of pigment in the thallus cortex is a useful taxonomic character in the genus.
