Agaricus augustus (NL: Reuzenchampignon / EN: the Prince / DE: Riesen-Champignon, Riesen-Egerling / FR: Agaric auguste, Agaric impérial)
is a basidiomycete fungus of the genus Agaricus. The specific epithet "augustus" is a Latin adjective meaning "noble". The fruiting bodies of Agaricus augustus are large and distinctive agarics. The cap shape is hemispherical during the so-called button stage, and then expands, becoming convex and finally flat, with a diameter of up to 22 cm. The cap cuticle is dry, and densely covered with concentrically arranged, brown-coloured scales on a white to yellow background. The flesh is thick, firm and white and may discolour yellow when bruised. The gills are crowded and pallid at first, and turn pink then dark brown with maturity. The specimen in the image shows a specimen at the optimum of maturity: the flat cap and brown gills are significant for this stage.
