The rhodopolioid species of Entoloma (subgen. Entoloma) in Norway are presented. The rhodopolioid clade consists of tricholomatoid or collybioid, rarely omphalinoid, ectomycorrhizal species. Altogether 24 species of the rhodopolioid clade were recorded and verified by rDNA ITS sequence data, of which 10 are here reported as new to Norway, including three apparently undescribed species. Four different eco geographical elements can be distinguished from our material; (i) the southern (boreonemoral) Tilia-Quercus-Corylus element, (ii) the boreal-arctic-alpine Salix-Alnus-Betula element, (iii) the arctic alpine Salix(-Dryas) element, and (iv) the boreal Betula(-Picea) element. All 24 species are commented in the taxonomic part, arranged according to the five well supported clades from phylogenetic analyses.
