Cap 2-6 cm broad, convex, broadly so to nearly plane in age, sometimes with a low umbo; margin at first incurved, then decurved, finally either plane or slightly raised; ground color cream-buff covered with vinaceous-brown to buff-brown appressed squamules or fibrils concentrated near the disc, diffuse towards the margin; surface bruising yellowish, eventually orange-brown, yellowing in KOH; flesh white to pallid, soft, thin; odor and taste of anise.
Gills free, close, moderately broad, at first cream, becoming light brown, at maturity dark-brown.
Stipe 3-7 cm tall 0.4-0.8 cm thick, round, stuffed, equal to tapering to an enlarged base; surface silky to finely longitudinally striate at the apex, elsewhere smooth or with scattered fibrils and scales, conspicuous rhizomorphs at the base; color white to cream, bruising yellowish to tawny-brown; veil membranous, thin, forming a narrow, fragile, buff to light-brown, superior ring, occasionally leaving fragments on the young cap.

This woodland Agaricus is recognized by its modest-sized, anise-odor, cap with vinaceous to brown appressed fibrils/squamules concentrated near the disc, and yellow to tawny bruising reaction. Other anise-odored, forest-dwelling Agaricus species include Agaricus silvicola, which is larger, cream-colored with a smooth cap and Agaricus diminutivus, a smaller, more slender, mushroom which usually lacks an umbonate cap. Another look-alike is Agaricus micromegathus, a rare, grassland species, also smaller, but otherwise similar.
