The =pileus= is convex, and in the young stage the margin strongly incurved, later the cap becomes expanded and has a very broad umbo. It is very viscid. The surface is covered with delicate hairs which form scales, more prominent during mid-age of the plant, and on the margin of the cap. These scales are very delicate and vary in color from vinaceous-buff, lilac, wine-purple, or lavender. The ground color of the pileus is vinaceous-buff or orange-buff, and toward the margin often with shades of beryl-green, especially where it has been touched. In the young plants the color of the delicate hairy surface is deeper, often phlox-purple, the color becoming thinner as the cap expands. The =gills= are notched (sinuate) at the stem, or adnate, sometimes slightly decurrent, crowded. Before exposure by the rupture of the veil they are cream-buff in color, then taking on darker shades, drab to hair brown or sepia with a purple tinge. The =stem= is yellowish, nearly or quite the color of the cap, often with a purplish tinge at the base. It is covered with numerous small punctate scales of the same color, or sulphur yellow above where they are more crowded and larger. The scales do not extend on the stem above the point where the veil is attached. The stem is slightly striate above the attachment of the veil. It is somewhat tough and cartilaginous, solid, or in age stuffed, or nearly hollow. The =veil= is floccose and quite thick when the plant is young. It is scaly on the under side, clinging to the margin of the pileus in triangular remnants, appearing like a crown. The color of the veil and of its remnants is the same as the color of the scales of the cap. The spores in mass are light brown, and when fresh with a slight purple tinge. (The color of the spores on white paper is near walnut brown or hair brown of Ridgeway's colors.) Under the microscope they are yellowish, oval or short oblong, often inequilateral, 6--8 × 4--5 µ. Figure 151 is from plants (No. 4016, C. U. herbarium) collected at Blowing Rock, N. C., September, 1899, on a fallen maple log. The plants sometimes occur singly. It has been collected at Ithaca, N. Y., and was first described from plants collected at Waynesville, Ohio. =Flammula sapinea= Fr., is a common plant growing on dead coniferous wood. It is dull yellow, the pileus 1--4 cm. in diameter, and with numerous small scales. HEBELOMA Fr. In _Hebeloma_ the gills are either squarely set against the stem (adnate) or they are notched (sinuate), and the spores are clay-colored. The edge of the gills is usually whitish, the surface clay-colored. The veil is only seen in the young stage, and then is very delicate and fibrillose. The stem is fleshy and fibrous, and somewhat mealy at the apex. The genus corresponds with _Tricholoma_ of the white-spored agarics. All the species are regarded as unwholesome, and some are considered poisonous. The species largely occur during the autumn. Few have been studied in America.
