Agaricus perobscurus, commonly known collectively with its close European relative Agaricus lanipes as the princess,[2] is a basidiomycete fungus. A relative of Agaricus augustus, known as the prince, A. perobscurus can be differentiated in several aspects. While the prince is widely distributed in North America, the princess is found only in the San Francisco Bay Area. Besides its smaller size, it is distinguished from Agaricus augustus by a darker-brown cap, a patchy fibrillose stipe surface at youth, lacking densely floccose-scaly, and a different fruiting season.[3] Another commonly closely associated Agaricus species, Agaricus praeclaresquamosus, is toxic. It can be differentiated by its dark-grey cap, a phenolic, rather than an anise odor, and a stipe base which yellows immediately when injured.[4][5]
