dry; lamellae broad, adnate or slightly decurrent, tawny-buff, 

 becoming brownish-ferruginous; stem slender, hollow, yellowish, 

 with a white mycelium at the base ; spores elliptical, .0003 in. 

 long, .00016 broad. 



Pileus 5 to 10 lines broad; stem 12 to 18 lines long, .5 to 1 

 line thick. 



Sticks and leaves under trees. Pasadena. January. McClatchie. 



When young, 'slight vestiges of a veil are visible, connecting 

 the incurved margin of the pileus with the stem. 



Pluteolus luteus. Pileus thin, at first subovate, then convex 

 or subcampanulate, glabrous, viscid, slightly striate on the margin, 

 yellow ; lamellae numerous, close, free or but slightly adnexed, yel- 

 lowish becoming ferruginous ; stem slender, hollow, slightly 

 thickened toward the base, striate at the top and there sprinkled 

 with mealy particles, yellowish; spores elliptical, .0004 to .0005 

 in. long, .00024 to .0003 broad. 



Pileus 6 to 12 lines broad; stem 1.5 to 2.5 in. long, 1 to 2 

 lines thick. Plant very fragile, gregarious. Under trees. Pasa- 

 dena. December. McClatchie. 



The yellow color and viscid pileus are prominent characters of 

 this species. In some of the dried specimens the lamellae appear 

 free, in others slightly adnexed, but because of the viscid pileus I 

 have referred the plant to the genus Pluteolus. 



Cortinarius virgatus. Pileus thick, fleshy, hemispherical or 

 convex, obtuse or subumbonate, slightly viscid, ochraceous tinged 

 with olive-buff, conspicuously virgate with reddish fibrils, flesh 

 dingy-white; lamellae subdistant, adnexed, at first subcinnamon, 

 then ochraceous-russet ; stem short, stout, solid, enlarged and 

 fibrillose at the base, pale-ochraceous ; spores subglobose or 

 broadly elliptical, .00024 to .0003 in. long, .0002 to .00024 broad. 



Pileus 3 to 4 in. broad; stems about 2 in. long, 8 to 12 lines 

 thick. 



Under oak trees. Pasadena. February. McClatchie. 



This species is well marked by its stout habit and by the red- 

 dish fibrils of the pileus. 



Agaricus Californicus. Pileus at first subconical, becoming 

 convex, minutely silky or fibrillose, whitish, tinged with purple or 

 brownish-purple on the disk, flesh whitish; lamellae close, free, 

 pink becoming purplish, then blackish-brown ; stem rather long, 

 solid or stuffed, equal or tapering upward, distinctly and rather 

 abruptly narrowed above the entire externally silky annulus, pallid
