New records of Lichinomycetes in Sweden and the Nordic countries

Six species of Lichinomycetes are newly reported for Sweden, of which three are also new for the Nordic countries. Lichinella stipatula is the first species of the mainly Mediterranean genus Lichinella s.str. found in the Nordic countries. The new records increase the number of Psorotichia species in Sweden and the Nordic countries to three (previously only one), Lichinella to two (considering Thallinocarpon nigritellum as belonging to Lichinella s.1.), and Anema species in Sweden to two (A. tumidulum and A. nummularium). The genus Metamelanea is recorded for the first time in Sweden with two species (M caesiella and M umbonata). Four of the six species were collected on the Baltic islands of Gotland or Oland in Sweden, growing on calcareous rocks in alvar habitats.
