Found in the Pacific Northwest region of North America, A. hondensis fruits in the fall under conifers or in mixed forests.

The fungus produces fruit bodies (mushrooms) with white to gray-brown caps up to 15 cm (6 in) in diameter covered with pale pinkish-brown scales that darken in age.

The species was first described as new to science by American mycologist William Alphonso Murrill in 1912, based on collections he made in November, 1911 under Californian redwoods.

In the same publication, Murrill also described the species Agaricus bivelatoides, A. hillii, and A. macmurphyi, all from the Pacific Northwest region of North America.

[3] In 1944, Alexander H. Smith examined the type material of several of Murrill's species, and concluded that were no characters to separate A. hondensis from A. bivelatoides, A. hillii, or A. macmurphyi.

Phylogenetic evidence suggests that these three species belong to a clade that diverged shortly after the presumed split of the sections Xanthodermatei and Duploannulati.

The dry and smooth cap surface is whitish or has pale pinkish-brown to pinkish-gray to fawn-colored flattened fibrils or fine fibrillose scales (at least in the center).

[8] Firm, smooth, and lacking the scales found on the cap, the stipe is white but discolors dingy pinkish or brownish in age or after handling.

[5] Distinctive field characteristics of Agaricus hondensis include its woodland habitat, the yellow staining reaction with KOH, and its odor.

[13] Another lookalike, the edible A. subrutilescens, has similar overall coloration, but is distinguished from A. hondensis by a mild odor, a shaggy stipe, and a less substantial ring.

[8] A saprobic species,[9] the fruit bodies of Agaricus hondensis grow scattered or in groups under conifers or in mixed forests.
