Agaricus (Psilocybe) caerulipes, n. sp. 



Pileus thin, subcampanulate, then convex and obtuse or obtusely 

 umbonate, glabrous, hygrophanous, slightly viscid, watery brown and 

 striatulate on the margin when moist, yellowish or subochraceous when 

 dry, the disk sometimes brownish ; lamellae at first ascending, close, 

 adnate, grayish-tawny, becoming ferruginous-brown, whitish on the 

 edge ; stem slender, equal, flexuous, tenacious, hollow or containing a 

 separable pith, slightly fibrillose, pruinose at the apex, bluish, some- 

 times whitish at the apex ; spores elliptical, .0003 to .0004 in. long, 

 .00016 to .0002 broad. 



Plant single or csespitose, 1 to 1.5 in. high, pileus 5 to 10 lines broad, 

 stem scarcely 1 line thick. 



Decaying wood. South Ballston. Aug. 



The species is easily recognized by the peculiar blue color of the 

 stem. Sometimes the pileus also assumes a blue color where bruised.

Cortinarius multiformis, Fr. 



Pine woods. Karner. Oct. 



Cortinarius decoloratus, Fr, 



Pine woods. Karner. Oct. 



Cortinarius (Dermocybe) aureifolius, n. sp. 



Pileus convex, then plane or slightly depressed, densely fibrillose- 

 tomentose, sometimes slightly squamulose, especially on the disk, cin- 

 namon-brown ; lamellae rather broad, moderately close, subventricose, 

 rounded behind, adnexed, yellow, becoming yellowish-cinnamon , stem 

 short, solid, equal, fibrillose, yellow, brownish within ; spores oblong, 

 .00045 to .0005 in. long, .00016 to .0002 broad ; flesh of the pileus 

 yellow or pallid, odor like that of radishes. 



Plant gregarious, 1 to 1.5 in. high, pileus 8 to 15 lines broad, stem 2 

 to 3 lines thick. 



Sandy soil in thin pine woods. Karner. Oct. 



The species resembles C cinndmomeus in color, but its short stem, 

 longer spores and different habit easily distinguish it. Its general ap- 

 pearance is similar to that of some species of Inocybe. 



Hygrophorus purpurascens, Fr. 



Sandy soil -under pine trees. Karner. Oct. 



In our specimens the pileus is fibrillose rather than squamulose, the 

 stem is slightly mealy at the apex, not roughened with purplish squa- 

 mules, and there is a webby veil which, in the young plant, conceals 

 the lamellae and forms a slight but evanescent annulus. Should these 

 differences between our specimens and the species to which we have 

 referred them be constant, it may be necessary to separate our plant 

 as a distinct species.
