... The formerly large genus Inocybe (Fr.) Fr. was recently divided into seven genera (Matheny et al. 2020) within the monophyletic familyInocybaceae Jülich. Of these genera, Inocybe is still the largest one with a number that will undoubtedly rapidly increase as further studies proceed from parts of the world such as Africa (e.g., Aïgnon et al. 2021aAïgnon et al. , 2021bBuyck et al. 2021Buyck et al. , 2022, India (Latha & Manimohan 2016, China (Fan & Bau 2010, 2013Fan et al. 2018;Mao et al. 2022) and Pakistan (Farooqi et al. 2017;Jabeen et al. 2016;Naseer et al. 2019;Khan et al. 2022), where DNA-basedInocybe studies has recently been started. ...
A new species in genus Inocybe is described and illustrated from Himalayan Moist Temperate forests of Pakistan. It is characterized by fibrillose, conical to convex, umbonate, brown to dark brown pileus, non-pruinose, fibrillose stipe with whitish tomentum at base, basidiospores smooth and comparatively larger (9 × 5.2 µm) and thicker caulocystidia (upto 21 m). Phylogenetic analyses of nuc rDNA region encompassing the internal transcribed spacers 1 and 2 along with 5.8S rDNA (ITS) and nuc 28S rDNA D1-D2 domains (28S) also confirmed its novelty.

To determine the taxonomic relationships of sequences from collections that were not Hebeloma, BLAST searches were carried out against GenBank (Johnson et al. 2008), UNITE (Kõljalg et al. 2005), and BOLD (Ratnasingham and Hebert 2007) databases. BLAST searches against our own data were done in Geneious R10 (Biomatters, Auckland, New Zealand) with default settings. ...
William Alphonso Murrill was an American mycologist of the early 20th century. He described 1453 new species of Agaricales, Boletales, and Polyporales. Within these were 44 taxa that he described as Hebeloma or that he recombined into Hebeloma. Additionally, there are five species, of which we are aware, that Murrill described within other genera that should be referred to the genus Hebeloma. A further three species described from northern America by J. P. F. C. Montagne, and transferred to Hebeloma by Saccardo, were commented on by Murrill and not accepted within the genus. These 52 taxa are analyzed here, both morphologically and molecularly, as far as possible. For 18 of his types, internal transcribed spacer (ITS) sequences were generated. For two species (H. harperi and H. subfastibile), which were mixed collections, lectotypes are designated. Twenty-three of the taxa analyzed are Hebeloma, as the genus is recognized today, and six of these (H. australe, H. harperi, H. paludicola, H. subaustrale, H. subfastibile, and H. viscidissimum) are regarded as current, i.e., they are names that should be accepted and used. Hebeloma paludicola is an earlier name for H. hygrophilum, described from Europe. Gymnopilus viscidissimus is synonymous with H. amarellum but has priority and is here recombined into Hebeloma. The remaining 17 Hebeloma taxa are synonymized with other species that have priority. The remaining 29 species belong to a range of genera; molecularly supported were Agrocybe, Cortinarius, Inocybe, Inosperma, Phlegmacium, Pholiota, Pseudosperma, and Pyrrhulomyces. Recombinations and synonymizations are made as appropriate and necessary. The names H. alachuanum and H. vatricosum, respectively Inocybe vatricosa, are considered doubtful and should be avoided.
... The Inocybaceae Jülich is a monophyletic family of ectomycorrhizal mushrooms which associates with more than 23 families of vascular plants (Matheny et al. 2019). Until recently the genus Inocybe (Fr.) Fr. (1863: 346) was phylogenetically divided into seven major clades (Matheny & Bougher 2006, Matheny 2009, Alvarado et al. 2010, Latha et al. 2016) considered as subgenera, but those were treated at the generic level by Matheny et al. (2019) as Inocybe sensu stricto, Inosperma (Kühner) Matheny & Esteve-Rav. (2019: 12), Mallocybe (Kuyper) Matheny, Vizzini, Esteve-Rav. ...
Inocybe hamadryadis sp. nov. is described and a detailed description, colour photographs, microdrawings and photographs of the microscopic features are provided. The type was found under Quercus ilex and Cistus ladanifer in Mediterranean habitat in Spain, but its distribution is throughout Europe and the West Asia. Inocybe hamadryadis is characterized by a finely textured, pale to dark brown or chestnut brown pileus with a faintly greyish velipellis, smooth basidiospores, hymenial cystidia with sinuous walls and caulocystidia only near the extreme apex of the stipe. Our analyses of the ITS and LSU regions, including coded indel information, indicate that I. hamadryadis is closely related to I. tenuicystidiata, from which it differs in several morphological features, such as the smaller basidiospores on average and the shorter caulocystidia.

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. obscuroide s, 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 .

Bandini D., Sesli E., Oertel B. & Krisai-Greilhuber I. (2020) Inocybe antoniniana, a new species of Inocybe section Marginatae with nodulose spores. – Sydowia 72: 95–106.
Inocybe antoniniana, a new species of Inocybe section Marginatae is described in detail along with illustrations of its macro-and micromorphology. It is a nodulose-spored species with yellowish-ochraceous pileus colour and smooth to (sub)rimulose pi-leus surface, that was found up to now in Turkey, Austria and Germany. It differs from other species of the group with equally coloured pilei (e.g. I. xanthomelas, I. phaeocystidiosa or I. krieglsteineri) by smaller, often (sub)isodiametrical basidiospores, rather short and slim hymenial cystidia, and ITS sequence data.

Eight new species presented are Calostoma areolatum collected in Wuyishan National Park (China), Crinipellis bidens from Hubei Province (China), Lactifluus sainii from Himalayan India, Inocybe elata from Yunnan (China), Inocybe himalayensis from Pakistan. Specimens previously identified as Massalongia carnosa represent a new species, namely M. patagonica restricted to southern South America. Saprolegnia maragheica is a new oomycete species of fresh water in Maraghe (Iran). Uncispora wuzhishanensis is a new aquatic hyphomycete species. A type specimen of Raddetes turkestanicus was studied and based on this the new combination Conocybe turkestanica, is proposed. Argyranthemum frutescens is a new host for Alternaria alternata and Syzygium cumini for Phyllosticta capitalensis in India. Crepidotus ehrendorferi is confirmed for Hungary and Pluteus leucoborealis for Central Europe, and for the phytogeographical region of Carpaticum. Pseudopithomyces palmicola is shown to occur on grapevine and it is validated by adding a unique identifier. Terfezia fanfani is reported first from Algeria.
... A second major lineage, Tubariomyces (recognized as the Mallocybella clade in Matheny 2009 andMatheny et al. 2009), has been described at the generic level (Alvarado et al. 2010). Four other major clades -Inosperma, Mallocybe, Nothocybe, and Pseudosperma -have been recognized but not yet formally named at generic ranks (Matheny 2005, Latha et al. 2016. Recognition of Auritella and Tubariomyces as separate genera renders Inocybe in the broad sense as a paraphyletic group but with poor support . ...
Two new species in the genus Auritella (Inocybaceae) are described as new from tropical rainforest in Cameroon. Descriptions, photographs, line drawings, and a worldwide taxonomic key to the described species of Auritella are presented. Phylogenetic analysis of 28S rDNA and rpb2 nucleotide sequence data suggests at least five phylogenetic species that can be ascribed to Auritella occur in the region comprising Cameroon and Gabon and constitute a strongly supported monophyletic subgroup within the genus. Phylogenetic analysis of ITS data supports the conspecificity of numerous collections attributed to the two new species as well as the monophyly of Australian species of Auritella. This work raises the known number of described species of Auritella to thirteen worldwide, four of which occur in tropical Africa, one in tropical India, and eight in temperate and tropical regions of Australia. This is the first study to confirm an ectomycorrhizal status of Auritella using molecular data.
... Our analysis of sequences from Inocybe s.str. (clade Inocybe; Latha et al. 2016) indicated three clades I-III. Typical characters include presence of thick-walled pleurocystidia, two kinds of cheilocystidia (both pleurocystidioid cheilocystidia and clavate to sphaeropedunculate paracystidia), smooth or angular or nodulose spores with fairly large apiculi; caulocystidia and a cortina may be either present (over a variable stipe length) or absent (Kuyper 1986, as I. subg. ...
Two smooth-spored Inocybe species, I. ahmadii (a new taxon) and I. leptocystis, were collected from moist temperate forests of Pakistan and identified based on molecular phylogenetic analysis and assessment of macro- and micro-morphological characters. Inocybe ahmadii is described as new based on its smooth phaseoliform to sub-amygdaliform basidiospores, pinkish brown lamellae, white stipe surface that is brownish at the apex, broadly lageniform hyaline pleurocystidia, and similar but more frequent cheilocystidia. Our I. leptocystis specimen, molecularly supported as conspecific with specimens from Austria, China, Italy, and Finland, represents a first record of the species from Pakistan.

... Notes:-Inocybe distincta has the following features: 1) small basidiomata with a subumbonate, finely squamulose-rimulose pileus with a mostly reflexed margin; 2) emarginate lamellae with a white, fimbriate edge; 3) a fibrillose-pruinose stipe with an abruptly ending base; 4) smooth, phaseoliform to ovo-ellipsoid basidiospores occasionally showing a slight angular outline; 5) copious, versiform, often septate cheilocystidia covered with a resinous substance towards the apex; 6) a hymenium devoid of pleurocystidia; 7) a cutis-type pileipellis disrupted by small patches of ascending hyphae and 8) a cutis-type stipitipellis with plentiful caulocystidia formed of modified terminal cells of stipitipellis hyphae towards the apex. The taxonomy and phylogeny of I. distincta were discussed in detail by Latha et al. (2016). ...
A systematic study on the agaric genus Inocybe (Inocybaceae, Agaricales, Basidiomycota) in Kerala State, India was performed based on both morphology and molecular phylogeny. The study revealed a total of thirty species belonging to the following four clades: Inocybe (twenty species), Pseudosperma (five species), Inosperma (four species) and Nothocybe (one species). Comprehensive descriptions, photographs and comparisons with phenetically similar and phylogenetically related species are provided for all these species of Inocybe. A key to the clades of Inocybaceae and keys to the Inocybe species of each clade discovered in Kerala are also provided. Twelve of these species are proposed here as new: I. babruka, I. floccosistipitata, I. insulana, I. kapila, I. kurkuriya, I. pingala, I. rekhankitha, I. silvana, I. snigdha and I. viraktha in clade Inocybe; and I. akirna and I. saraga in clade Inosperma. A combined nLSU and rpb2-based phylogenetic analysis using Maximum likelihood (ML) method supported both the novelty of the new species and the placement of all the thirty species of Inocybe within the respective clades. Based on morphological, geographical and phylogenetic evidences, the following species recently described from Kerala are considered as heterotypic (taxonomic) synonyms: Inocybe albonitens a synonym of I. wayanadensis, I. parvisquamulosa that of I. iringolkavensis and I. rimulosa that of I. keralensis. The majority of the inocybes discovered in this study were found associated with Hopea parviflora, H. ponga and Vateria indica of the angiosperm family Dipterocarpaceae. In addition, the authors observed that in Kerala, one can find Inocybe species only in those forests or woodlands that have dipterocarps. The consistent association of the Inocybe species with the family Dipterocarpaceae in this region is remarkable.
