Appearance

The cap ranges from 7 to 20 cm across, is convex, and is bright yellow-orange in younger specimens and orange/brown or reddish brown in older ones, with a dry scaly surface. The stem is 2.5 to 26.5 cm long, 1 to 4 cm thick, and often narrows near the base. The frail ring is dusted with rusty orange spores, the flesh is yellow and the gill attachment to the stem is adnate to sub-decurrent. It has a bitter taste, stains red with KOH and turns green when cooked in a pan. The spore print is rusty orange. It occasionally bruises blue, especially smaller specimens or "runts". This mushroom usually grows in clusters from several to several dozen individuals, but sometimes grows solitary.
