“…Additionally, Zhao et al (2016) proposed a new taxonomic system that classified Agaricus into five subgenera and 20 sections based on divergence times [2]. In subsequent studies, 2 of 22 new subgenera and sections were established based on the new taxonomic system;presently, Agaricus comprises six subgenera and 27 sections [6,[10][11][12][13][14].…”

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.

“…Zhao et al (2016) proposed the segregation of this genus into five subgenera and 20 sections, considering the evolutionary divergence time as a standard taxonomic criterion. Other studies (Kerrigan 2016, Chen et al 2017, He et al 2018, Parra et al 2018, Ortiz-Santana et al 2021) have contributed to a better knowledge of the systematics of the genus and it currently consists of seven subgenera and 32 sections, although A. subg. Conioagaricus Heinem.…”

In Mexico, there are 55 wild species of Agaricus representing approximately 10 % of the world's diversity of the genus. 22 species of these wild mushrooms are traditionally consumed. The lack of keys for the identification of Mexican species, the difficulties in recognizing distinctive morphological characters and the need for comprehensive studies in some sections of the genus, makes it difficult to distinguish species complexes. The edible species known locally as "ojo de venado" was previously identified as A. sylvaticus in Mexico. Our phylogenetic analyses revealed that this ethnotaxon, which is sold in the markets of Xalapa (Veracruz, Mexico), includes at least two species of A. sect. Subrutilescentes. One of them, Agaricus cervinoculus, is described as a new species. A full description, photographs and comparisons to other similar species are provided. This new species constitutes a well-supported monophyletic clade, sister to the "A. subrutilescens" group.

“…Agaricus L. (Agaricaceae, Basidiomycota) includes saprotrophic mushrooms of medicinal, nutraceutical and nutritional interest. The genus has a worldwide distribution comprising around 580 species [1][2][3][4][5][6]. According to Zhao et al [7], the diversity of the genus Agaricus is clearly underestimated.…”

“…Mata et al [ 8 ] reported 32 species for Mexico; Medel et al [ 9 ] concluded that in Mexico tropical cloud forest is the ecosystem with the greatest diversity of species of Agaricus ; Palestina-Villa et al [ 10 ] updated the nomenclature of the species known from Mexico. Regarding the Dominican Republic, two works with the description of 19 taxa have been recently published [ 6 , 11 ].…”

Agaricus is a genus of fungi in the family Agaricaceae, with several highly priced edible and medicinal species. Here we describe Agaricus macrochlamys, a new species, in A. sect. Arvenses, sympatric and morphologically cryptic with the edible and medicinally cultivated mushroom, A. subrufescens. Phylogenetic analyses showed that A. macrochlamys is closely related to A. subrufescens, and that A. fiardii is a new synonym of A. subrufescens. Despite being morphologically cryptic, A. macrochlamys can be distinguished from A. subrufescens by several ITS and tef1α species-specific markers and a 4-bp insertion in the tef1α sequence. Furthermore, A. subrufescens is a cosmopolitan species, while A. macrochlamys distribution is so far restricted to Mexico, the Dominican Republic, and the United States.
