Abstract: Two rare, orange to red-veiled species, Cortinarius rubrovioleipes Bendiksen & K. Bendiksen and C. hinnuleoarmillatus Reumaux, are studied morphologically and based on the molecular data (ITS-sequences). The distribution of species in Fennoscandia is mapped, their taxonomy and ecology discussed, and colour photographs provided. C. rubrovioleipes is reported for the first time since the description of the species. Also the relationship to C. boulderensis A.H. Sm. and C. pseudobovinus M. M. Moser & McKnight is discussed. The species are here placed in a new section Boulderenses Niskanen, Liimatainen & Kytöv. Short descriptions of North American C. boulderensis and C. pseudobovinus are provided based on the original descriptions and the type material. The nomenclature of species is confirmed by sequencing the type material.
