Advances in the knowledge of the Inocybe mixtilis group (Inocybaceae, Agaricomycetes), through molecular and morphological studies.
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.
期刊介绍:
Persoonia aspires to publish papers focusing on the molecular systematics and evolution of fungi. Additionally, it seeks to advance fungal taxonomy by employing a polythetic approach to elucidate the genuine phylogeny and relationships within the kingdom Fungi. The journal is dedicated to disseminating high-quality papers that unravel both known and novel fungal taxa at the DNA level. Moreover, it endeavors to provide fresh insights into evolutionary processes and relationships. The scope of papers considered encompasses research articles, along with topical and book reviews.
