This is a conspicuous bright yellow or honey-yellow toadstool, with a glistening slimy cap which, as well as the stalk, is beset with concentric darker scales (Fig. 289). The scales and delicate annulus become indistinct or disappear on old sporophores or after much rain. The stalk is thick, fleshy, and stiff, and while growing so changes its direction as to keep the cap always in a horizontal position. The pileus or cap, at. Fig. 289.—Agaricus adiposi/s. A, A mature and a very young sporophore grown in the forest; the other sporophores were raised on Fir-wood in a cellar. The latter have longer thinner stalks, and a basal swelling beset with white down. B, Mature and germinating spores, (v. Tubeuf del.) first globose, opens out cone-shaped or flat with a diameter of about 5 cm. Eemains of the velum adhere to the margin. The underside of the cap is at flrst yellow, later mouse-grey. The lamellae are of three sizes, the largest extending from margin to stalk. From the lamellae arise the basidia, with four sterigmata each giving off a single spore. The spores fall at maturity, and cover neighbouring objects with a brown dust. They are oval with a length of 7-10^ and a breadth of 5-6/x. The sporophores spring up rapidly in large numbers on ' V.
