This paper is a compilation of notes on 142 fungal taxa, including five new families, 20 new genera, and 100 new species, representing a wide taxonomic and geographic range. The new families, Ascocylindricaceae, Caryosporaceae and Wicklowiaceae (Ascomycota) are introduced based on their distinct lineages and unique morphology. The new Dothideomycete genera(More)
Cortinarius is a species-rich and morphologically challenging genus with a cosmopolitan distribution. Many names have not been used consistently and in some instances the same species has been described two or more times under separate names. This study focuses on subg. Phlegmacium as traditionally defined and includes species from boreal and temperate(More)
This is a continuity of a series of taxonomic papers where materials are examined, described and novel combinations are proposed where necessary to improve our traditional species concepts and provide updates on their classification. In addition to extensive morphological descriptions and appropriate asexual and sexual connections, DNA sequence data are(More)
Cortinarius sect. Armillati (subgenus Telamonia) was studied extensively based on morphology and molecular data. A total of about 1000 specimens, mostly from Fennoscandia, were revised. The nomenclature of the species was confirmed by sequencing the type material. Phylogenetic relationships were inferred by analyses of ITS, and the results were compared(More)
The section Brunnei was extensively studied based on material from North Europe. To stabilise the nomenclature we studied the relevant types of taxa included in this section. Phylogenetic relationships and species limits were investigated using rDNA ITS sequences and the results were compared with the morphological data. We recognised 11 species:(More)
Cortinarius bovinus and morphologically similar conifer-associated species were studied using material mainly from northern Europe. To stabilize the nomenclature, relevant types were examined. Phylogenetic relationships and species limits were investigated with rDNA ITS and nuclear rpb2 sequences as well as morphological data. We recognize seven species: C.(More)
Cortinarius disjungendus and morphologically similar species were studied using ITS sequences of nine type collections and 18 specimens in the study group, as well as 13 sequences from public sequence repositories, including sequences of three type specimens. In addition, previously published rpb2 sequences were used to provide the phylogenetic position of(More)
Two new Cortinarius species are described from European Quercus forests and one new combination is made based on molecular and morphological data. Cortinarius uraceomajalis is a vernal species currently only known from Hungary, Bulgaria and Italy, but likely is common throughout central and south-eastern Europe. Cortinarius uraceonemoralis is a widely(More)
The red species of Cortinarius subgenus Dermocybe in Europe were studied based on morphological and molecular data. Three completely red species were recognized: C. sanguineus (syn. C. sanguineus var. aurantiovaginatus), C. puniceus (syn. C. cruentus, C. rubrosanguineus) and C. vitiosus comb. nov. Cortinarius sanguineus has dusky red to red pileus, reddish(More)
Two new Cortinarius species, C. brunneifolius and C. leiocastaneus, are described based on molecular and morphological data. Cortinarius brunneifolius looks like a trivial brown Telamonia. It is characterised by the fairly dark brown cap and gills contrasting with the white stem. The major distinctive features are the refracting, colourless granules in the(More)
