Inocybe brijunica sp. nov., a New Ectomycorrhizal Fungus from Mediterranean Croatia Revealed by Morphology and Multilocus Phylogenetic Analysis

Two new species of Inocybe from Mediterranean Cistaceae heathlands

This study explored a heathland region in Portugal, and through morphology, biogeography, and multilocus phylogeny, two new species of Inocybaceae are described. The first species, Inocybe iberilepora, belongs to "I. flocculosa group," whereas the second species, Inocybe phaeosquamosa, belongs to a relatively isolated and understudied clade, distantly related to I. furfurea and allies. Both species are tied to a west Mediterranean distribution and ecology, associating with the local Cistaceae ecosystems. By characterizing these new species, our research contributes to the understanding of European Funga and enriches the knowledge of the genus Inocybe on a global scale.

A fresh outlook on the smooth-spored species of Inocybe: type studies and 18 new species

On the basis of detailed morphological and molecular investigation, eighteen new species of Inocybe (I. alberichiana, I. beatifica, I. bellidiana, I. clandestina, I. drenthensis, I. dryadiana, I. gaiana, I. ghibliana, I. grusiana, I. knautiana, I. lampetiana, I. oetziana, I. orionis, I. plurabellae, I. rivierana, I. scolopacis, I. sitibunda and I. tiburtina) are described. All of them are smooth-spored, and most of them are pruinose only in the apical part of the stipe. The new species are compared to 40 type specimens, all of which are described here and for several of which (partial) ITS sequences have been generated. For eight species, epi-, lecto- or neotypes were selected, among these are I. geophylla, I. glabripes and I. tigrina. Based on these studies, we suggest twelve synonymies, i.e. that I. clarkii is synonymous with I. sindonia, I. conformata with I. cincinnata, I. elegans with I. griseolilacina, I. fuscidula with I. glabripes, I. griseotarda with I. psammobrunnea, I. obscurella with I. obscuroides, I. obscuromellea with I. semifulva, I. patibilis and I. tigrinella with I. tigrina, I. petroselinolens with I. tenuicystidiata and I. rubidofracta with I. pseudorubens and I. subporospora is synonymized with I. tjallingiorum. All of the new species are supported by phylogenetic analyses. Among the previously described species accepted here, sixteen are represented by types in the phylogenetic analyses and ten by own collections morphologically corresponding to the type. In summary, we here verify or provide morphological concepts associated with molecular data for 44 smooth-spored species of Inocybe.

Two new toxic yellow Inocybe species from China: morphological characteristics, phylogenetic analyses and toxin detection

Some species of Inocybe s. str. caused neurotoxic poisoning after consumption around the world. However, there are a large number of species in this genus that have not been studied for their toxicity or toxin content. In this study, we report two new toxic yellow Inocybe s. str. species from China based on morphological characteristics, phylogenetic analyses and toxin detection. Among the two species, Inocybesquarrosolutea is reported as a newly recorded species of China. We also describe a new species, I.squarrosofulva, which is morphologically similar to I.squarrosolutea. The new species is characterized by its ochraceous squarrose pileus, distinctly annulate cortina on the stipe, nodulose basidiospores and thick-walled pleurocystidia. Muscarine in the fruitbodies was detected by UPLC-MS/MS, the content in I.squarrosolutea and I.squarrosofulva were 136.4 ± 25.4 to 1683.0 ± 313 mg/kg dry weight and 31.2 ± 5.8 to 101.8 ± 18.9 mg/kg dry weight, respectively.
