OCHRE-SPORED AGARICS. 153 



Pholiota johnsoniana Pk. Edible. This species was described from 

 specimens collected at Knowersville, N. Y., in 1889, by Peck, in the 

 23rd Report N. Y. State Mus., p. 98, as Agaricus johnsonianus. I 

 found it at Ithaca, N. Y., for the first time during the summer of 

 1899, and it was rather common during September, 1899, in the Blue 

 Ridge Mountains at Blowing Rock, N. C. It grows in woods or in 

 pastures on the ground. The larger and handsomer specimens I 

 have found in rather damp but well drained woods. The plants are 

 7-15 cm. high, the cap 5-10 cm. broad, and the stem 6-12 mm. in 

 thickness. 



The pileus is fleshy, very thick at the center, convex, then ex- 

 panded and plane, smooth, sometimes finely striate on the thin mar- 

 gin when moist, yellowish, or fulvous, the margin whitish. The gills 

 are attached to the stem by the upper angle (adnexed), rounded, or 

 some of them angled, some nearly free. In color they are first gray, 

 then rusty brown. They appear ascending because of the somewhat 

 top-shaped pileus. The spores are irregularly ovoid, 4-6 x 3-3.5 ^. 

 The stem is cylindrical or slightly tapering upward, smooth, slightly 

 striate above the annulus, whitish, solid, with a tendency to become 

 hollow. The veil is thick, and the annulus narrow and very thick or 

 "tumid," easily breaking up and disappearing. The plant is quite 

 readily distinguished by the form of the pileus with the ascending 

 gills and the tumid annulus. Peck says it has a " somewhat nutty 

 flavor."

 at Blowing Rock, N. C, during September, 1899. 



NAUCORIA Fr. 



> 



This genus, with ferruginous spores, corresponds with Collyhia 

 among the white-spored agarics. The gills are free or attached, but 

 not decurrent, and the stem is cartilaginous. The plants grow both 

 on the ground and on wood. Peck, 23rd Report N. Y. State Mus., p. 

 91, et seq., gives a synopsis of seven species. 



Naucoria seiiii=orbicularis Bull. Edible. This is one of the common 

 and widely distributed species. It occurs in lawns, pastures, road- 

 sides, etc., in waste places, from June to autumn, being more abund- 

 ant in rainy weather. The plants are 7-10 cm. high, the cap 3-5 

 cm. broad, and the stem 2-3 mm. in thickness. The pileus is convex 

 to expanded, and is remarkably hemispherical, from which the species 

 takes the name of semi- orbicularis. It is smooth, viscid when moist, 

 tawny, and in age ochraceous, sometimes the surface is cracked 

 into areas. The gills are attached, sometimes notched, crowded,
