Type studies on entolomatoid species in the Velenovský Herbarium—I. Species described in the genera Nolanea, Leptonia and Telamonia

All types of entolomatoid fungi available in the Velenovský Herbarium at Prague have been studied. In this first report the types of 30 species described by Velenovský in Nolanea, Leptonia and Telamonia (one species) are described. Species accepted here have, if necessary, been transferred to Entoloma, which resulted in 18 new combinations and 4 new names. One described in Nolanea had to be transferred to Pluteus.
