The phylogeny of the Entolomataceae was reconstructed using three loci (RPB2, LSU and mtSSU) and, in conjunction with spore morphology (using SEM and TEM), was used to address four main systematic issues: 1) the monophyly of the Entolomataceae; 2) inter-generic relationships within the Entolomataceae; 3) genus delimitation of Entolomataceae; and 4) spore evolution in the Entolomataceae. Results confirm that the Entolomataceae (Entoloma, Rhodocybe, Clitopilus, Richoniella and Rhodogaster) is monophyletic and that the combination of pinkish spore prints and spores having bumps and/or ridges formed by an epicorium is a synapomorphy for the family. The Entolomataceae is made up of two sister clades: one with Clitopilus nested within Rhodocybe and another with Richoniella and Rhodogaster nested within Entoloma. Entoloma is best retained as one genus. The smaller genera within Entoloma s.l. are either polyphyletic or make other genera paraphyletic. Spores of the clitopiloid type are derived from rhodocyboid spores. The ancestral spore type of the Entolomataceae was either rhodocyboid or entolomatoid. Taxonomic and nomenclatural changes are made including merging Rhodocybe into Clitopilus and transferring relevant species into Clitopilus and Entoloma.

Two new species of Agaricales, and , are described from Mount Tianmu, Zhejiang Province, Eastern China. Two new species are distinct and monophyletic based on morphology and phylogenetic analyses. differs from other species in that the pileus is brow shallow in the center and stipe with yellowish white fibrils, scatted on litter under coniferous and broad-leaved mixed forest at 1162 m.

In Malaysia, mushroom poisoning poses a significant public health concern, particularly as local communities frequently consume wild mushrooms without fully recognizing the potential dangers they present. Ingestion of wild mushrooms, which resemble edible species but contain deadly chemicals, is the main cause of poisoning risk. The genus Entoloma (Fr.

is a relatively large genus in Agaricales, with a rich diversity of species and a wide distribution. In this study, seven new species of belonging to the subgenus have been identified based on morphological and phylogenetic evidence from subtropical regions of China. Morphologically, is characterized by the yellow, depressed, estriate pileus and medium-sized basidiospores; is recognized by the white and papillate pileus, adnexed lamellae, and presence of clamp connections; is identified by the pink-to-maroon and estriate pileus, and lamellae with lateral veins; differs from other cuboid-spored species by the lamellae edge which is red-brown-underlined; is characterized by the white pileus and carneogriseum-type cheilocystidia; is recognized by the pileus margin exceeding the lamellae, 2-layered pileipellis with hyphae of different widths, and the presence of clamp connections; is identified by the tomentose pileus, heterogeneous lamella edge, and versiform cheilocystidia with brown-yellow contents.

The phylogenetic position of several clitocyboid/pleurotoid/tricholomatoid genera previously considered is here resolved using an updated 6-gene dataset of including newly sequenced lineages and more complete data from those already analyzed before. Results allowed to infer new phylogenetic relationships, and propose taxonomic novelties to accommodate them, including up to ten new families and a new suborder. (for which a new species from China is here described) forms a monophyletic clade with () nested inside suborder , together with the families , (including ), and .

A revision, based on morphological and multigene analysis, of the species currently present in Europe is provided. Portions of nrITS rDNA, nr28S rDNA (LSU), RNA polymerase II second largest subunit (), translation elongation factor 1-alpha (), and ATPase subunit 6 (), were used to sort out the relationships of the species within the genus. Three subgenera were recognized: subg.
