The Cortinarius (telamonioid) species of sect. Safranopedes (= sect. Rubricosi s. auct.) in Norway are presented, with emphasis on our calcareous Tilia forest species. Altogether 15 species from the section are now known from Norway. Most of these species must be regarded as so far little known, overlooked or misidentified. The species can be sorted in four groups in Norway; (i) more or less habi- tat-specific calcareous Tilia forest species (Cortinarius elaphinicolor, C. epipurrus, C. milvinicolor, C. parhonestus), (ii) small species in rich Corylus-Quercus-Tilia forests (C. russulaespermus, C. subexitiosus, C. subscotoides), (iii) small species mainly in conifer forests or with Betula (C. annae-maritae, C. comptulus, C. nigrocuspidatus, C. aff. pauperculus, C. subobtusus) (iv) very small taxa associated mainly with Salix spp., including arctic-alpine populations (C. paululus, C. pauperculus, C. scotoides). The calcareous Tilia forests taxa include the core group of sect. Safranopedes; mediumsized taxa with violet KOH-reaction in context and often radicate, saffron yellow spotted stipe and context. This core group includes C. epipurrus (= C. pseudosafranopes) which seems not uncommon in Europe, and three apparently widespread but rare species, only known from a few localities outside SE Norway: C. milvinicolor is distinguished on its initially olivaceous grey brown colours, C. parhonestus on more vivid fulvous colours and C. elaphinicolor being more or less intermediate. A presentation and nomenclatural discussion on the type species of the section, C. safranopes is included, although this species is so far not confirmed from Norway. barcoding, Cortinariaceae, morphology, nrDNA-ITS sequences, taxonomy, TelamoniaTelamonioide slørsopper (Cortinarius), seksjon Safranopedes i Norge, med fokus på arter i kalklindeskog
