California, Miss Patterson, H. S. Fazvcett, McClatchie, Baker. 



2. Drosophila atrofolia (Peck) 

 Hypholoma atrofolium Peck, Bull. Torrey Club 23: 417. 1896. 



Pileus submembranous, at first convex or hemispheric, then 

 broadly convex, commonly umbonate, minutely and irregularly 

 furrowed, striate to the apex when mature, hygrophanous, burnt- 

 umber or wood-brown when moist, fading to pale-tawny or 

 cream color in drying, veil fugacious ; lamellae subdistant, adnate, 

 at first pale-brown or drab, then dark seal-brown, almost black; 

 stem slender, fibrillose, hollow, pallid or cream color ; spores very 

 dark brown, ellipsoid, 10 X 5ft-; pileus 18-48 mm. broad; stem 

 2.5-6 cm. long, 2-3 mm. thick. 



Described from plants collected by McClatchie among bushes 

 at Pasadena, California. At Albany, specimens from Cahfornia 

 collected by Copeland and also from Ohio collected by Lloyd bear 

 this name. The gills of the type are almost black when mature, 

 suggesting Psathyrella, but its relationships are nearer Hypho- 

 loma, according to the author. 



3. Drosophila longipes (Peck) 

 Hypholoma longipes Peck, Bull. Torrey Club 22: 204. 1895. 



Pileus thin, campanulate, even or obscurely striate on the 

 margin, fibrillose becoming glabrous, hygrophanous, yellowish- 

 brown when moist, brown or isabelline-brown when dry, the 

 margin appendiculate with the very white, floccose, fugacious 

 veil; lamellae narrow, close, adnate, white or whitish, becoming 

 nearly black, often whitish on the edge ; stem slender, long, hol- 

 low, striate at the top, white, with a mycelioid tomentum at the 

 base; spores ellipsoid, 12.5 X 7-5 /x- 



Pileus 2.5-3 broad; stem 5-12.5 cm. long, 2-5 mm. thick. 



Described from specimens collected by McClatchie in very wet 

 weather among fallen leaves near Pasadena, California. Very 

 thin and fragile, with stipe hollow to the very apex. Specimens 

 at Albany from California sent to Dr. Peck by Miss Patterson 

 in 1907 are incorrectly referred to this species.
