Abstract

A Study of freshwater Verrucaria s.l. species is presented. Specimens have been collected from the bedsand banks of lakes, rivers and streams, in 92 localities from the Iberian Peninsula. An identification key of the13 freshwater taxa is also proposed. Four of these are new records for Portugal: Hydropunctaria rheitrophila,Verrucaria funckii, V. hydrela and V. pachyderma. Most of them are widespread throughout the Iberian Peninsula,except for V. mundula, previously recorded for the first time in the Northern Hemisphere in 2010.
