=C. ful´vo-tomento´sus= Pk.—tawny-tomentose. =Pileus= ¾-2 in. broad, scattered or gregarious, suborbicular, kidney-shaped or dimidiate, sessile or attached by a short, white-villose tubercle or rudimentary stem, hygrophanous, watery-brown and sometimes striatulate on the margin when moist, whitish, yellowish or pale ochraceous when dry, _adorned with small, tawny, hairy or tomentose scales_. =Lamellæ= broad, subventricose, moderately close, rounded behind, radiating from a lateral or eccentric white villose spot, whitish becoming brownish-ferruginous. =Spores= _elliptical_ often uninucleate, 8–10×5–6µ. Decaying wood of poplar, maple, etc. Common. June to October. A pretty species, corresponding in some respects to the European C. calolepis, but much larger and with tawny, instead of reddish scales. The cuticle is separable and is tenacious, though it has a hyaline gelatinous appearance. The pileus is subpersistent, and specimens dried in their place of growth are not rare. _Peck_, 39th Rep. N.Y. State Bot. Haddonfield, N.J.; Angora, West Philadelphia. On decaying hickory. _McIlvaine._ Substance fair. Taste strong but pleasant. [Illustration: Grouped by F.D. Briscoe—Studies by C.

CORTINARIUS OCHRACEUS, 319 =CORTINA´RIUS= Fr. _Cortina_, a veil or curtain. =Veil= resembling the consistency of a cob-web, superficial, distinct from the cuticle of the pileus. =Flesh= of pileus and stem continuous. =Gills= persistent, dry, changing color, powdered with the spores. =Trama= fibrillose. =Spores= globose or oblong, somewhat ochraceous on white paper. _Fries._ This genus is not easily confounded with any other, the cob-webby veil stretched from stem to pileus in the young plant not being found in other fungi. This must be looked for only in youth, as from its tender character it soon breaks and often appears only as a very indistinct collar on the stem, colored from catching the falling spores. The colors are generally pronounced and often extremely bright, there being very few prettier toadstools than those inclined to the blue or purple shades, which are not uncommon in the immature form. The color of the spores is also a marked feature, being rusty or brownish-ochraceous, turning the gills to the same color at maturity. On account of this change it is generally necessary to have specimens at both stages of growth to accurately determine the species. The gills are thin, attached to the stem in various manners, rarely slightly decurrent. Cortinarius is distinguished from Flammula by growing on the ground and by the bright ferruginous color of its spores.
