Grant support

First and foremost, we thank Dr F. Javier Rejos, curator at AH for help and concern in our research work. Thanks are also given to the curators of KR, M, PC and TUR-A, for their kindness and attention in responding to our loan requests. We are indebted to Jukka Vauras (Turku, Finland), Erminio Ferrari (Verbana Suna, Italy), Agustin Caballero (La Rioja, Spain), Roberto Fernandez-Sasia (Basque Country, Spain), Enrico Bizio (Venezia, Italy), Jordi Vila (Catalonia, Spain), Josef Christan (Munchen, Germany), Matthias Dondl (Munchen, Germany) and Markus Rave (Heidelberg, Germany), for sending us samples, photographs and collections from their private herbaria and make our job much easier. Also, we appreciate the effort of all those who contributed with collections to this study (see Materials and Methods). We also extend our thanks to Mr. Antonio Priego and Mr. Jose A. Perez (Electron Microscopy Service, University of Alcala de Henares), for their invaluable help with the SEM. We also thank Luis Monje and Angel Pueblas (Department of Drawing and Scientific Photography, University of Alcala de Henares) for their help in the digital preparation of many photographs. We acknowledge Pablo Alvarado for sequencing part of the material used in this study. Vicente Gonzalez wants to thank personally Mrs MA Portal for her technical service. This study has been partially funded by a project granted by the Spanish Science Council (CGL2017-86540-P) to F. Esteve-Raventos and G. Moreno.

Resúmen: Inocybe mixtilis constitutes a complex of species characterized by nodulose-angulose spores, absence of cortina and a more or less bulbous marginate stipe that is not darkening when desiccated. In order to elucidate species limits within the I. mixtilis complex, an ITS-RPB2 phylogeny was performed and interpreted using morphological and ecological characters. Six supported clades were obtained in our analyses that correspond to I. mixtilis, I. subtrivialis, and four new species to science: I. ceskae, I. johannis-stanglii, I. nothomixtilis and I. occulta. Species within this complex can be morphologically recognized through a unique combination of morphological characters, such as the spore shape, cystidial length and shape, presence and development of the velipellis and pileus colour and viscidity. Nevertheless, those characters overlap, especially among I. mixtilis, I. ceskae and I. occulta, and intermediate collections are therefore more reliably identified through ITS-sequencing. Two species, I. ceskae and I. occulta are present in both North America and Europe, while the rest are so far only known in Europe, or Europe and Asia (I. mixtilis). All species, except I. johannis-stanglii, seem to be able to establish ectomycorrhizal association both with conifers and angiosperms. Descriptions, colour illustrations and a key to all known species in the I. mixtilis group are provided.
