Abstract
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.

Abstract
We describe four new nodulose-spored species of Inocybe from tropical regions of Africa: I. beninensis, I. flavipes, I. fuscobrunnea and I. pallidiangulata. The new species are recognised based on morphological data and phylogenetic analyses of ITS, 28S and RPB2 sequences. Phylogenetic analyses indicated that I. flavipes and I. beninensis are part of a subclade leading to the I. calida group. Inocybe fuscobrunnea appears sister to the I. asterospora group. Inocybe pallidiangulata is nested within a clade of mainly tropical species from South Asia, Africa, and South America, close to the subclade of I. lilacinosquamosa and I. ayangannae from Guyana. Complete descriptions and illustrations, including photographs and line drawings, and a key to nodulose-spored taxa of tropical African species of Inocybe are provided.

Abstract
Many species of Inosperma cause neurotoxic poisoning in humans after consumption around the world. However, the toxic species of Inosperma and its toxin content remain unclear. In the present study, we proposed five new Inosperma species from China, namely, I. longisporum, I. nivalellum, I. sphaerobulbosum, I. squamulosobrunneum, and I. squamulosohinnuleum. Morphological and molecular phylogenetic analyses based on three genes (ITS, nrLSU, rpb2) revealed that these taxa are independent species. A key to 17 species of Inosperma in China is provided. In addition, targeted screening for the most notorious mushroom neurotoxins, muscarine, psilocybin, ibotenic acid, and muscimol, in these five new species was performed by using ultrahigh-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Our results show that the neurotoxin contents in these five species varied: I. sphaerobulbosum contains none of the tested neurotoxins; I. nivalellum is muscarine positive; I. longisporum and I. squamulosohinnuleum contain both ibotenic acid and muscimol, and I. squamulosobrunneum only contains muscimol; psilocybin was not detected in these five new species.

Abstract
Twelve new species of Inocybe (I. adorabilis, I. comis, I. demetris, I. filiana, I. galactica, I. morganae, I. othini, I. ovilla, I. proteica, I. somae, I. suryana and I. venerabilis) are described from Europe on the basis of detailed morphological and molecular investigation. A portrait of the recently described I. ianthinopes is given. All species are smooth-spored and some pruinose only in the apical part of the stipe, and some on entire length. The new species are compared to 24 type specimens (17 characterized by at least partial ITS sequence data), all of which are described and revised here. Epitypes were selected for two species, I. hirtella and I. sindonia. Based on our studies, we confirm that I. kuehneri and I. sindonia on one hand, and I. subalbidodisca and I. ochroalba on the other, are synonyms and furthermore suggest that I. abietis is synonymous with I. catalaunica, I. exilis with I. rufobrunnea, I. hirtellarum with I. mycenoides, I. lapidicola with I. deianae, I. ochraceolutea with I. sindonia, I. stangliana with I. pelargonium, I. subrubens with I. subhirtella and I. sulfovirescens with I. langei. All of the new species are supported by phylogenetic analyses. Among the 16 previously described species accepted here, 10 are represented by types in the phylogenetic analyses and five by own collections corresponding to the type. Two species, I. eutheloides (remaining doubtful) and I. pallidolutea are only treated morphologically. In summary, we describe as new or verify the taxonomic status and provide or corroborate morphological concepts for 37 smooth-spored species of Inocybe.

Abstract
Ectomycorrhizal symbiosis appears extensively in the Northern Hemisphere, where Mediterranean ecosystems constitute an important ecological area of considerable biodiversity value. Littoral sand dunes are among high-risk habitats, and ectomycorrhizal lifestyle contributes significantly to supporting life in such regions. Mallocybe heimii (Bon) Matheny & Esteve-Rav. (Inocybaceae, Basidiomycota) and the very similar M. arenaria (Bon) Matheny & Esteve-Rav. grow in poor, usually sandy soils, in association with angiosperms or gymnosperms. Basidiomata originally identified under these names were collected from littoral sand dunes of Greece, and their morpho-anatomical characteristics were examined in conjunction with material derived from other European regions. Sequences from basidiomata and root tips corresponding to the nuclear rDNA internal transcribed spacer region (ITS) and large subunit (LSU) were obtained and analyzed. Phylogenetic results demonstrated that material identified as M. heimii or M. arenaria form a single well-supported group, while M. agardhii (N. Lund) Matheny & Esteve-Rav. is confirmed to be distinct from M. arenaria (the latter was initially described as a variety of the former, i.e., I. agardhii var. arenaria Bon). A detailed tree of the genus Mallocybe was generated on the basis of concatenated ITS and LSU sequences, and relationships of selected taxa are discussed in the light of morphological and sequence data. In addition, the first morphotype descriptions of M. heimii ectomycorrhizae with Cistus creticus L. and Pinus halepensis Miller are hereby provided. Both morphotypes exhibited the typical characteristics of Inocybe/Mallocybe ectomycorrhizae; however, differences were noted, the most significant being the presence of clamps on mantle hyphae and the type of anastomoses.

Abstract
A new ectomycorrhizal species was discovered during the first survey of fungal diversity at Brijuni National Park (Croatia), which consists of 14 islands and islets. The National Park is located in the Mediterranean Biogeographical Region, a prominent climate change hot-spot. Inocybe brijunica sp. nov., from sect. Hysterices (Agaricales, Inocybaceae), is described based on morphology and multilocus phylogenetic data. The holotype collection was found at the edge between grassland and Quercus ilex forest with a few planted Pinus pinea trees, on Veli Brijun Island, the largest island of the archipelago. It is easily recognized by a conspicuous orange to orange-red-brown membranaceous surface layer located at or just above the basal part of the stipe. Other distinctive features of I. brijunica are the medium brown, radially fibrillose to rimose pileus; pale to medium brown stipe with fugacious cortina; relatively small, amygdaliform to phaseoliform, and smooth basidiospores, measuring ca. 6.5-9 × 4-5.5 µm; thick-walled, utriform, lageniform or fusiform pleurocystidia (lamprocystidia) with crystals and mostly not yellowing in alkaline solutions; cheilocystidia of two types (lamprocystidia and leptocystidia); and the presence of abundant caulocystidia only in the upper 2-3 mm of the stipe. Phylogenetic reconstruction of a concatenated dataset of the internal transcribed spacer region (ITS), the nuclear 28S rRNA gene (nrLSU), and the second largest subunit of RNA polymerase II (rpb2) resolved I. brijunica and I. glabripes as sister species.

Abstract
Sequestrate fungi have enclosed hypogeous, subhypogeous, or epigeous basidiomes and have lost the ability to actively discharge their spores. They can be distinguished as gasteroid (basidiome fully enclosed with a loculated hymenophore) or secotioid (basidiome with some agaricoid or pileate-stipitate features, but the lamellae are misshapen and unexposed or mostly unexposed at maturity). There are only four reports of sequestrate taxa within the ectomycorrhizal family Inocybaceae, three from Australia and one from western North America. Recent field work in Nothofagaceae forests in the Chilean coastal range revealed novel sequestrate forms of Inocybe. We examined specimens using a combination of morphological and molecular data from nuc rDNA internal transcribed spacer region ITS1-5.8S-ITS2 (ITS) and portions of nuc 28S rDNA (28S) and the gene encoding the second largest subunit of RNA polymerase II (rpb2). Here, we describe four new sequestrate Inocybe species, I. ranunculiformis, I. anfractuosa, I. illariae, and I. nahuelbutensis. Results of our phylogenetic analysis resolved the four new species as distinct species-level clades with strong support, suggesting that these fungi have convergently evolved sequestrate forms independently. The species described here were all placed along with members of the "smooth-spored temperate austral clade," which includes almost exclusively Australasian and South American species of Inocybe.

Abstract
Inocybe (Inocybaceae) is one of the most diverse ectomycorrhizal genera in arctic and alpine habitats where the primary hosts are Salix, Betula, and Dryas. Subgenus Inocybe is common in these habitats and typically characterized by the presence of thick-walled pleurocystidia. Here, we focus on species that have angular or nodulose spores. Historically, over 30 taxa from this group have been reported from arctic and alpine habitats. Many names have been synonymized, whereas molecular analysis has revealed new species. Nuc rDNA internal transcribed spacer ITS1-5.8S-ITS2 (ITS) sequence data of 26 type specimens in this group now allow for further taxonomic clarification and comparison across continents of disjunct populations. Here, we compare ITS sequence data and the D1-D2 portion of nuc 28S rDNA (28S) from Rocky Mountain specimens with those of types and European reference material. We report 10 species from the Rocky Mountain alpine zone, all of which are conspecific with known European boreal, montane, or alpine species, and four are described as new; all have intercontinental distributions. Nodulose-spored Inocybe taxa that occur in the Rocky Mountain alpine zone include I. alpinomarginata, sp. nov., I. arctica, I. giacomi, I. leonina, I. murina, sp. nov., I. occulta, I. paragiacomi, sp. nov., I. phaeocystidiosa, I. purpureobadia, and I. subgiacomi, sp. nov. Remarkably, these species occur at elevations up to 4000 m and at latitudes as low as 36°N, hundreds of miles from the Arctic, the European alpine, and original type localities. Distributions are explained in part by host distributions and historical glaciation patterns. A key and full descriptions for Rocky mountain species are provided to promote species recognition.

Abstract
Results of a study on species of Inocybe section Rimosae sensu lato in Utah are presented. Eight species, seven from the Pseudosperma clade (section Rimosae sensu stricto) and one from the Inosperma clade (section Rimosae pro parte), are documented morphologically and phylogenetically. Five of the eight species, I. aestiva, I. breviterincarnata, I. cercocarpi, I. niveivelata and I. occidentalis-all members of the Pseudosperma clade-are described as new from Utah and other western states. Two European species, I. spuria and I. obsoleta, are confirmed from Utah. Inocybe aurora, originally described from Nova Scotia, is synonymized with I. obsoleta. The only member of the Inosperma clade recorded from Utah is I. lanatodisca, a widely distributed species for which three geographical clusters were detected. The phylogenetic analyses indicate that the Pseudosperma clade includes 53 clusters or species worldwide and that the Inosperma clade includes 47 such clusters. Many of these probably correspond to undescribed species. A key to species of section Rimosae sensu lato from Utah is provided together with illustrations of the eight species found in the state.
