=Height= 2–4 in., breadth of pileus 2–3 in. =Stem= 4–6 lines thick at the top, 12–18 lines at the base. Under balsam trees in open places. Catskill mountains. October. The stem appears as if sheathed. In some specimens the stem is short and rapidly tapers from the base to the top. _Peck_, 23d Rep. N.Y. State Bot. Many of the species were found by the writer in mixed woods among leaves at Mt. Gretna, Pa., September, 1898. Specimens were identified by Professor Peck. The gills are bright yellow when young. Cap smooth, innately fibrillose, not viscid. =Spores= light brown. Tasteless; smell faint. Good consistency. A fair flavor develops in cooking. *** _Gills yellow._ (Plate LXXXVI_b_.) [Illustration: CORTINARIUS ANNULATUS. Natural size. ] =C. (Inoloma) annula´tus= Pk. =Pileus= broadly convex, dry, villose-squamulose, yellow. =Flesh= yellowish. =Lamellæ= rather broad, subdistant, adnexed, yellow. =Stem= solid, bulbous, somewhat peronate by the yellow fibrillose annular-terminated veil. =Spores= broadly elliptical or subglobose, 8µ long. =Pileus= 1–3 in. broad. =Stem= 1.5–3 in. long, 3–6 lines thick. Thin woods. Whitehall. August. The whole plant is yellow inclining to ochraceous. It has the odor of radishes. The squamules of the pileus are pointed and erect on the disk, and often darker-colored there. The species is allied to C. tophaceus and C. callisteus, from which it is separated by its persistently annulate stem and more yellow color. _Peck_, 43d Rep. Specimens received from E.B. Sterling, Trenton, N.J., September 5, 1897. Identified by Professor Peck. Mixed woods Kingsessing, near Bartram’s Garden, Philadelphia, September, 1897. Solitary among grass and leaves. The permanent marking of the veil is conspicuous. Eight specimens were found and eaten. The caps cook tender, and have a decided but not unpleasant flavor. DERMO´CYBE. (_Gr_—skin; _Gr_—a head.) =C. cinnabari´nus= Fr.—_cinnabaris_, dragon’s blood. =Pileus= 2–3 in. broad, _scarlet-red_, truly fleshy, campanulate, then flattened, obtuse or very obtusely umbonate, silky, then becoming smooth and shining, or obsoletely scaly; the firm flesh paler. =Stem= 1½-2 in. long, 3–4 lines and more thick, solid, equal, sometimes however bulbous, fibrillose or striate, scarlet-red, reddish brick-color internally. Cortina fibrillose, lax, cinnabar. =Gills= wholly adnate, somewhat decurrent, 3 lines broad, somewhat distant, connected by veins, unequal and darker at the edge, dark blood-color when bruised. Odor of radish. Readily distinguished from all others by its _splendid scarlet color_, and from C. sanguineus by its short solid and firm stem, its broad pileus and _somewhat distant gills_. Stem never becoming yellow. _Fries._ =Spores= 7–8×4µ _Cooke_. It is a variable species with us.
