Taxonomy
Taxonomic history
The species was first described by French mycologist Lucien Quélet as Psalliota bernardi in 1879, based on collections made in La Rochelle, a seaport on the Bay of Biscay (France).[3] Pier Andrea Saccardo transferred it to Agaricus in 1887.[1]

Etymology
The species was named after the original collector, G. Bernard.[3] A. bernardii is commonly known as the salt-loving mushroom.[11]
Synonyms include Psalliota bernardii, Pratella bernardii, Fungus bernardii, and Agaricus campestris subsp. bernardii.[1]
Description

Fruit bodies of A. bernardii have caps that range in shape from convex to flattened, and reach a diameter of 5–15 centimetres (2–6 inches). The cap surface is dry and smooth, with a white or buff color that can develop brownish spots in maturity. In age, the surface often forms scales or warts. The flesh is thick, firm, and stains reddish-orange or reddish-brown when cut, although this reaction can be slow to develop.[12] Its odor ranges from mild to briny to pungent.[13] The gills are free from attachment to the stem, and packed close together. Initially grayish-pink to pinkish, they turn reddish-brown and then chocolate brown as the spores mature. The stem is solid (i.e., not hollow), firm, and measures 4–10 cm (1+1⁄2–4 in) long by 2–4 cm (1–1+1⁄2 in) thick. A thick, white, rubbery partial veil covers the gills of the immature mushroom, and eventually remains as a ring on the middle of the stem.[12]

A. bitorquis, also edible, has a similar appearance, but can be distinguished by its double ring, and the lack of a fishy or briny odor. Additionally, A. bitorquis does not stain reddish when cut, and usually does not have a scaly or warty cap.
Distribution and habitat
The species is found in Asia, Europe, North America[11] (including Mexico)[15] and New Zealand.[12]

Ecology
A Czech study determined that the mushrooms will strongly bioaccumulate silver from contaminated soil. Although the average concentration of silver in the soil is typically less than 1 milligram per kilogram of soil, it can be significantly elevated near industrial sites such as mines and smelters. The concentration of silver in the caps—which reached levels of up to 544 mg per kg of mushroom tissue (dry weight)—was about twice that of the stems.[18]
Uses
Although the mushrooms sometimes have an odor that is briny or pungent,[11] they are edible and good.[19] David Arora compares it to the closely related A. bitorquis, "but a little chewier".[13]
