Conocybe belongs to the Bolbitiaceae. The morphological classification and molecular phylogenetics of Conocybe section Pilosellae are not in agreement. In this study, based on the specimens from China, we investigated the sect. Pilosellae and identified 17 species, including 7 new species: Conocybe pilosa, with a densely hairy pileus and stipe; C. reniformis, with reniform spores; C. ceracea, with waxy dehydration of the lamellae; C. muscicola, growing on moss; C. sinobispora, with two-spored basidia; C. hydrophila, with a hygrophanous pileus; C. rufostipes, growing on dung with a brown stipe; and C. pseudocrispa, one new record for China. A key was compiled for the sect. Pilosellae in China. Here, the sect. Pilosellae, and new species and records from China are morphologically described and illustrated. Maximum likelihood and Bayesian analyses were performed using a combined nuc rDNA internal transcribed spacer region (ITS) and nuc 28S rDNA (nrLSU), and translation elongation factor 1-alpha (tef1-α) dataset to reconstruct the relationships of this section. We found that the sect. Pilosellae was the basal clade of Conocybe, and its evolutionary features may shed light on the characteristics of Conocybe. By integrating morphological classification and phylogenetic analysis, we explored the possible phylogenetic relationships among the species of the sect. Pilosellae in China.

Agaricus belongs to Agaricaceae and is one of the most well-known macrofungi, with many edible species. More than 300 Agaricus specimens were collected during a three-year macrofungal resource field investigation in Northeast China. Based on morphological observations and multi-gene (ITS + nrLSU + tef1-a) phylogenetic analyses, six new Agaricus species, i.e., Agaricus aurantipileatus, A. daqinggouensis, A. floccularis, A. griseopileatus, A. sinoagrocyboides, and A. velutinosus, were discovered. These new species belong to four sections within different subgenera: A. (subg. Agaricus) sect. Agaricus, A. (subg. Flavoagaricus) sect. Arvenses, A. (subg. Minores) sect. Minores, and A. (subg. Pseudochitonia) sect. Xanthodermatei. Morphological descriptions, line illustrations, and basidiomata photographs of these new species are provided, and their differences from similar species are discussed.

“…Based on multi-locus phylogenetic analyses (Matheny et al 2006 ; Lodge et al 2014 ; Zhao et al 2017 ), the positions of many taxa in Agaricales have been anchored. To date, 8 suborders, 46 families, 482 genera, and more than 40,000 species have been allocated to the order (Vizzini et al 2019 ; Kalichman et al 2020 ; Mou and Bau 2021 ; Bánki et al 2022 ).…”

The order Agaricales was divided into eight suborders. However, the phylogenetic relationships among some suborders are largely unresolved, and the phylogenetic positions and delimitations of some taxa, such as Sarcomyxaceae and Tricholomopsis , remain unsettled. In this study, sequence data of 38 genomes were generated through genome skimming on an Illumina sequencing system. To anchor the systematic position of Sarcomyxaceae and Tricholomopsis , a phylogenetic analysis based on 555 single-copy orthologous genes from the aforementioned genomes and 126 publicly accessible genomes was performed. The results fully supported the clustering of Tricholomopsis with Phyllotopsis and Pleurocybella within Phyllotopsidaceae, which formed a divergent monophyletic major lineage together with Pterulaceae , Radulomycetaceae , and Macrotyphula in Agaricales . The analysis also revealed that Sarcomyxaceae formed a unique major clade. Therefore, two new suborders, Phyllotopsidineae and Sarcomyxineae , are proposed for the two major lineages. Analyses of 450 single-copy orthologous genes and four loci suggested that Tricholomopsis consisted of at least four clades. Tricholomopsis is subsequently subdivided into four distinct sections. Seventeen Tricholomopsis species in China, including six new species, are reported. Conoloma is established to accommodate T. mucronata . The substrate preference of Tricholomopsis species and the transitions of the pileate ornamentations among the species within the genus are discussed.
