4. Drosophila campanulata (Peck) 



Hypholoma campanulatum Peck, Bull. Torrey Club 36: 336. 

 1909. 



Pileus thin, campanulate, dry, somewhat shining, glabrous, 

 sometimes slightly appendiculate with fragments of the white 

 veil, ochraceous ; lamellae thin, close, nearly free, pale-brown 

 becoming dark-brown, whitish on the edge; stem long, equal, 

 glabrous, hollow, white or cream-colored with a soft white tomen- 

 tum at the base; spores blackish-brown, ellipsoid-oblong, 8-10 X 

 4-5 Z^- 



Pileus 3-4 cm. broad; stem 8-13 cm. long, 4-7 mm. thick. 



Described from specimens collected by Baker in open ground 

 among shrubs, grass, and weeds, at Claremont, CaHfornia. Prob- 

 ably too closely related to H. hngipes Peck, according to speci- 

 mens examined at Albany. 



5. Drosophila calif ornica (Earle) 



Hypholoma calif orntcum Earle, Bull. N. Y. Bot. Card. 2 : 344. 

 1902. 



Densely cespitose on or near the base of oak stumps ; pileus 

 thin, 5-5.5 cm., convex, then expanded and subumbonate, deep 

 rich-brown, smooth, hygrophanous, margin entire (or obscurely 

 striate in dried specimens) ; lamellae adnexed or subfree, sub- 

 crowded, slightly ventricose, pale-brown at first then darker; 

 spores dark purplish-brown, oblong-ellipsoid, 5-6 X 3 ; veil 

 white, of thin fibers soon breaking away from the stem but more 

 closely woven toward the margin, appendiculate; stalk 7-10 cm. 

 X 4-5 mm., equal, glabrous but uneven with small irregular 

 swellings, sordid-white marked with brownish stains on drying, 

 hollow, cartilaginous, fragile, often splitting; flesh thin, pale- 

 brownish, unchanging, taste and smell mild (normal agaric). 



Described from specimens collected on the summit of the Coast 

 Range, near Palo Alto, California, Baker 86. Related to H. 

 longipes Peck, but larger, with ventricose gills and smaller spores. 



6. Drosophila ambigua (Peck) 

 Hypholoma amhigiium Peck, Bull. Torrey Club 25 : 325. 1898. 



Pileus thin, convex, becoming nearly plane, glabrous, sub- 

 viscid when moist, straw color inclining to pale-orange, the mar-
