Var. _pusil´la_ Pk. Plant small. =Pileus= about 1 in. broad, passing gradually into the typical form. =Stem= slender. Professor Peck says: “The variety furfuracea is common and connects this species with C. longipes, which has a villose stem and dry velvety pileus.” 49th Rep. Common to the United States. Edible. _Curtis_, according to Dr. F. Peyre Porcher of Charleston, S.C., was the first to declare this edible. A very attractive species. The purity of its gills is especially noticeable. I began eating it in 1881, and it has continued to be a favorite. The caps should be broiled or fried. They are sweet, pleasing in texture, and delicately flavored. =C. platyphyl´la= Fr. _Gr._—broad; a leaf. (Plate XXVIII, fig. 1, p. 114.) =Pileus= 3–4 in. broad, dusky and gray then whitish, fleshy-membranaceous, _thin, fragile_, soon flattened, obtuse, watery when moist, _streaked with fibrils_. =Stem= 3–4 in. long, ½ in. thick, stuffed, soft, equal, fibrilloso-striate, otherwise smooth, naked or obsoletely powdered at the apex, whitish, shortly and bluntly rooted at the base. =Gills= obliquely cut off behind, _slightly_ adnexed, ½ in. and more _broad, distant_, soft, white. Odor not remarkable. It inclines toward the Tricholomata in the _somewhat membranaceous cuticle of the soft stem_. _Fries._ =Spores= 13×19µ _W.G.S._ Solitary, gregarious, rarely clustered. On rotten wood, roots, ground near stumps, among leaves, etc. June to October. [Illustration: Grouped by F.D. Briscoe—Studies by C. McIlvaine. PLATE XXVIII.] FIG. PAGE. FIG. PAGE. 1. COLLYBIA PLATYPHYLLA, 114 3. COLLYBIA DRYOPHILA, 120 2. COLLYBIA PLATYPHYLLA 114 4. COLLYBIA FUSIPES, 116 (AFTER RAIN), Distinguished by the very broad and deeply emarginate gills, which frequently slope up behind to near the cap then with a short turn downward connect with the stem which is either stuffed or hollow, and by the abundant, cord-like rooting mycelium. The gills are very broad. Professor Peck says: “The species is quite variable. The pileus is sometimes irregular and even eccentric, the thin margin may be slightly striate, is often split and in wet weather may be upturned or revolute. The lamellæ are sometimes ½ in. broad or more and transversely split. They may be obscurely striated transversely and even veiny above with venose interspaces. Occasionally a slight anise-like odor is perceptible, but in decay the plants have a very disagreeable odor and disgusting appearance.” 49th Rep. N.Y. State Bot. West Virginia, 1880–1885; Haddonfield, N.J., 1896. Gregarious, and in large bunches. Mt. Gretna and Eagle’s Mere, Pa., 1897, _McIlvaine_. When fresh, in good condition, the caps are good, but they are not nearly equal in substance or flavor to C. radicata and C. longipes. They are best broiled or fried.
