The fungal genus Agaricus as late as 2008 was believed to contain about 200 species worldwide.[1] Since then, molecular phylogenetic studies have revalidated several disputed species, as well as resolved some species complexes, and aided in discovery and description of a wide range of mostly tropical species that were formerly unknown to science. As of 2020, the genus is believed to contain no fewer than 400 species, and possibly many more.
The medicinal mushroom known in Japan as Echigoshirayukidake (越後白雪茸) was initially also thought to be an Agaricus, either a subspecies of Agaricus "blazei"[2] (i.e. A. subrufescens), or a new species.[3] It was eventually identified as sclerotium of the crust-forming bark fungus Ceraceomyces tessulatus, which is not particularly closely related to Agaricus.
Several secotioid (puffball-like) fungi have in recent times be recognized as highly aberrant members of Agaricus, and are now included here. These typically inhabit deserts where few fungi–and even fewer of the familiar cap-and-stalk mushroom shape–grow. Another desert species, A.zelleri, was erroneously placed in the present genus and is now known as Gyrophragmium californicum. In addition, the scientific names Agaricus and–even more so–Psalliota were historically often used as a "wastebasket taxon" for any and all similar mushrooms, regardless of their actual relationships.
