“…Agaricus is widely distributed in both temperate and tropical areas throughout the world ( Kerrigan et al, 2005 , Kerrigan, 2016 ; Chen et al, 2015 ; Zhao et al, 2016 ; He et al, 2017 , 2018a,b ; Callac and Chen, 2018 ; Ling et al, 2021 ). Morphological characteristics have been traditionally used in the identification of specimens of the Agaricus species.…”

“…To date, a total of over 500 species of Agaricus are currently recognized. These include many new species from America, Asia, Australia, and Europe (Wang et al, 2015;Kerrigan, 2016;He et al, 2017;Callac and Chen, 2018) and few new species from Africa (Hama et al, 2010;Zhao et al, 2012b;Ling et al, 2021) and Oceania (Geml et al, 2007;Lebel and Syme, 2012;Lebel, 2013). Among the approximately 200 new species described since 2000, more than half have been reported to be from Asia, and a quarter have been reported in America (particularly North America) (Zhao et al, 2011(Zhao et al, , 2016Thongklang et al, 2014a;Liu et al, 2015;Karunarathna et al, 2016;Kerrigan, 2016;Chen et al, 2017;Callac and Chen, 2018;Hyde et al, 2018).…”

Agaricus is a saprophytic mushroom genus widely distributed throughout the world. In this study, a survey of the Agaricus species carried out around Chiang Mai University in northern Thailand from 2018 to 2019 yielded 12 collections. Morphological characteristics and phylogenic analyses based on the internal transcribed spacers (ITS) and a fragment of the large subunit (LSU) of the nuclear ribosomal DNA (rDNA), and a fragment of the translation elongation factor 1-alpha (tef1) genes were investigated. The results revealed that these collections belong to six species including Agaricus erectosquamosus, Agaricus pallidobrunneus, Agaricus subrufescens, and three new species. Agaricus thailandensis sp. nov. was found to belong to Agaricus sect. Minores, which is placed in Agaricus subg. Minores. Aagricus pseudoerectosquamosus sp. nov. was placed in Agaricus sect. Brunneopicti within Agaricus subg. Pseudochitonia. Furthermore, Agaricus lannaensis remains an incertae sedis in Agaricus subg. Pseudochitonia. Additionally, this study was proposed that A. pallidobrunneus was discovered in Thailand for the first time. Full descriptions, color photographs, illustrations, and phylogenetic trees are provided.

“…A total of 5% KOH were used for a staining reaction. More than twenty measurements of microscopic features (spores, basidia, and cystidia) were recorded, which included tx, the mean of the length by the width ± SD; Q, the quotient of the basidiospore length to width; and Qm, the mean of the Q-values ± SD [ 17 , 20 ].…”

The species of Agrocybe (Strophariaceae, Agaricales, Agaricomycetes) are saprophytic and widely distributed in temperate regions. In this study, a new species named Agrocybe striatipes from China is described, which has been successfully cultivated in China recently. The phenotypic characteristics examination and molecular phylogenetic analyses using multilocus data (ITS and nrLSU) both support it as a new species in the genus Agrocybe. Moreover, nutritional ingredient analysis showed that the fruiting body of A. striatipes was rich in seventeen amino acids, including eight essential amino acids, in addition to high levels of calcium (78.5 mg/kg) and vitamin D (44.1 μg/100g). The following analysis of the heavy metal contents of the fruiting bodies show that it does not contain lead, cadmium, arsenic, mercury, and other heavy metal elements. In the crude extract of the mushroom, the nutrients in the aqueous phase are amino acids and oligosaccharides, and the active substances in the ethyl acetate layer are sterols, which have a variety of pharmacological effects. In conclusion, A. striatipes is not only a new species but also has highly application values as a cultivated edible mushroom in nutrition and health.

“…Agaricus species are abundant; so far, more than 500 species have been recorded [1-3,7,17 -20]. At present, over 116 Agaricus species supported by molecular phylogenetic and morphological studies have been reported in China [9,[21][22][23][24][25][26][27]. However, the richness of Agaricus species diversity in some regions of China still needs to be studied and explored, such as Northeast 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.
