Three new Entoloma species of the Cyanula clade from (sub)alpine habitats in Northern Norway and Sweden

Three Entoloma species belonging to the Cyanula clade from (middle-) northern boreal and alpine areas are described as new to science. Entoloma montanum, E. nordlandicum, and E. septentrionale, recorded from the Holmvassdalen area at Grane, North- ern Norway while E. montanum shows a wide distribution in Northern Scandinavia and the Caucasus. Entoloma nordlandicum, however, has recently been recorded also from the Netherlands. The three species are phylogenetically well defined based on analysis of the nrDNA ITS region and they are distant from their closest relatives. Morphological descriptions of each species are given, as well as their ecology, distribution and relationships towards similar species are discussed.
