When T. personatum becomes known to the collector, either in the field or on the table, it is sure to become a favorite. It is fleshy, rotund, stocky, moist and smooth, with a tendency in its cap to be wavy-rimmed and jauntily cocked in wet weather. It grows singly or in troops, occasionally in tufts of from five to six individuals. A patch of it is valuable and worth husbanding with covering of fine straw. Cortinarius violaceus resembles it somewhat in color and shape, but it shows a spidery veil, and has brown spores. It is edible. The common name of T. personatum in England is Blewits, which translated into understandable English is believed to be “blue-hats.” It is everywhere eaten, being of substantial substance, good flavor and cookable in any way. It is especially fine in patties, stews and croquettes. =T. nu´dum= Bull.—naked. =Pileus= about 3 in. broad, becoming purple-violaceous then changing color, reddish, fleshy, comparatively _thin_, convexo-plane then _depressed_, obtuse, even, smooth, with a pellicle which is moist and manifest in rainy weather; margin inflexed, thin, naked. =Flesh= thin, pliant, colored. =Stem= about 3 in. long, ½ in. thick, _stuffed, elastic_, equal, _almost naked_, mealy at the apex, _violaceous then becoming pale_. =Gills= rounded then decurrent (on account of the depressed pileus), crowded, narrow, of the same color as the pileus or deeper _violaceous_, but soon changing color, at _length reddish_ without the least tinge of violet. _Stevenson._ =Spores= 7×3.5µ _Massee_; 6–8×4µ _B._; 6×3µ _W.G.S._ On ground among leaves. Esculent, very good and delicate. _Cordier._ Edible. _Roze._ Edible, all American authorities. VII.—HYGROPH´ANA. Pileus thin, water-soaked, etc. * _Gills whitish, not spotted._ =T. grammopo´dium= Bull. _Gr._—a line; _Gr._—a foot. =Pileus= 3–6 in. broad, _pallid-livid_ or brownish-red when moist, whitish when dry, fleshy, very thin toward the margin, _campanulate then convex_, and at length flattened, obtusely umbonate, even, smooth, pellicle moist in rainy weather, not viscous, separating, flesh-colored when moist, white when dry, soft, fragile. =Stem= _tall_, about 3–4 in. long, ½ in. and more thick, _solid_, elastic, equal with exception of the _thickened base_, cylindrical, firm, smooth, _evidently longitudinally sulcate, whitish_. =Gills= arcuato-adnate or broadly horizontally emarginate, acute at both ends, _very crowded, quite entire_, very many shorter, somewhat branched behind, white. Odor moldy. Striking in appearance; the chief of this group. There is a variety wholly white. In pastures and grassy woods. _Stevenson._ =Spores= 5–6µ _Massee_. Distinguished by the grooved stem and crowded gills, which are adnate when the pileus is expanded. Often growing in rings. North Carolina, _Curtis_. Not reported elsewhere.
