The aim of this study is to carry out a taxonomic revision of the groups Calamistratum and Geraniodorum of the genus Inosperma sect. Inosperma in Europe. For this purpose, a multigenic phylogenetic ...analysis was carried out using the ITS, LSU, RPB1 and RPB2 markers, covering a total of 111 sequences, including those generated from the existing type-material collections. This analysis led to the recognition of nine clades or terminal groups for the European continent, correlating with nine morphological species. Three of them, I. calamistratum, I. neohirsutum sp. nov. and I. turietoense sp. nov., are distributed in humid and temperate forests, whereas I. geminum sp. nov., I. geraniodorum, I. gracilentum sp. nov., I. praetermissum comb. nov., I. subhirsutum and I. veliferum seem to be restricted to the colder altimontane, boreal and alpine climates. It is concluded that the study of morphological and ecological characteristics allows the recognition of species without the need for an often-subjective interpretation of organoleptic characteristics. Inocybe hirsuta is considered a synonym of Inosperma calamistratum, Inosperma praetermissum as a different species from I. calamistratum, and Inocybe geraniodora var. gracilenta f. salicis-herbaceae as a synonym of I. praetermissum. Four new species and one new combination are proposed. A key for the recognition of the European species is provided. Illustrations and photographs of macro- and micromorphological characters and SEM spores of all species are presented.
The taxonomy of Inocybe similis and closely allied species is addressed using morphological and molecular data (nrITS and nrLSU DNA). The holotypes of I. chondrospora and I. vulpinella and the ...isotype of I. immigrans were studied and sequenced. Our results suggest the synonymy between I. similis and I. vulpinella as well as that between I. chondrospora and I. immigrans.
The new species Inocybe flavobrunnescens is described on the basis of morphological and genetic features. It is characterized by (sub)isodiametric spores; it has a variable number of low and obtuse ...knobs, lageniform cystidia, and habitat preference for thermophilous oak woods on calcareous soils. It is compared with type material of Inocybe xanthomelas and I. krieglsteineri, which share with the new species a darkening flesh and small to medium sized basidiomes. ITS analysis revealed a low intraspecific variability within each Inocybe lineage, suggesting their accommodation as independent species. On the basis of this DNA region, I. xanthomelas and I. krieglsteineri are closely related. The present work suggests also updating several names in public databases to accommodate the present taxonomic conclusions. A lectotype for I. xanthomelas is designated.
Three closely related species in Alnicola sect. Alnicola, Alnicola, are described, illustrated, and compared. Alnicola badia is revised based on the type collection and recent collections made under ...Alnus alnobetula. Two species (A. longicystis,
A. xanthophylla) associated with Alnus glutinosa and A. incana and locally frequent in western and central Europe are described as new.
