Etymology: Agaricales is a Latinized formal name, not a word that grew organically in English, and its history begins with a single genus. The name comes from "Agaricus," the Latin genus name for mushrooms, which was itself adapted from "agaricum," a Latin term for a bracket fungus (a woody shelf-like fungus) used in medicine. That Latin word came from Greek "agarikon," and the Greek term is thought to derive from Agaria, a region in Sarmatia (around the Sarmatian lands north of the Black Sea), though this ancient geographical link is uncertain. The ending "-ales" is the standard taxonomic suffix for an order, a convention fixed by botanical nomenclature rules in the 19th century. Mycologists formalized these ranks as the field systematized mushroom classification, so the order name was built by taking the type genus and adding the suffix. Agaricales thus names an order defined by the group that includes the genus Agaricus, rather than a description written first and a name chosen afterward.
