Entoloma species of subgenus Cyanula (Tricholomatinae, Basidiomycota) in Norway, with emphasis on habitat preferences and distribution

Abstract

This is the third paper with results from the Norwegian Entoloma project 2015-2017. An overview is given of the species of Entolomasubgenus Cyanula in Norway. Cyanula includes, among other elements, many grassland fungi. This paper is part of a larger studyconcerning the European species of the subgenus Cyanula, including a multigene phylogeny that will be published in due course.Furthermore, a monograph with updated taxonomic revision is recently issued. This paper focuses mainly on the species recorded from Norway with help of ITS DNA barcoding, with reference to recent collections also from Northern Sweden, with extensive notes of their habitat requirements and distribution. Altogether 53 Cyanula species are presented here, with an updated circumscription and naming. More than half of these are reported new to Norway since the start of the Norwegian Entoloma project. Of these, 18 have been described as new during the last three years, largely based on Norwegian material. Four of these are known exclusively from Scandinavia.
