The numerous uurrow and elongated basidia of this species are 

 suggestive of the specific name. The plant is also easily recognized 

 by the peculiar, pale, livid gray hue of the pileus, and the slight 

 violaceous tint of the laniellas. The pileus is rarely slightly umbo- 

 nate. When dry both it and the stem have a slight silky appearance. 

 The stem is usually solid, and slightly enlarged as it enters the 

 pileus. The species should be placed among the Orbiformbs, though 

 in some respects it approaches C. ohhatus and O. Calathus. It also 

 has the aspect of some species of Hygroi)horus. 



CoUylbia alcalinoleiis. 



Pileus thin, subconieal or convex, then expanded, slightly silky- 

 fibrillose, shining, hygrophanous, dark watery-brown when moist, 

 grayish-])rown or cinereous when drj^ flesh white ; lamellte rather 

 broad, subdistant, adnate or emarginate with a decurrent toothy 

 whitish ; stem equal, glabrous, slightly pruinose above, hollow, 

 shining, whitish ; spores broadly elliptical, .0003 to .00035 in. long, 

 .0002 to .00025 in. broad. 



Plant gregarious, 1 to 2 in. high, pileus 8 to 18 lines broad, stem 

 1 to 3 lines thick. 



Thin woods and bushy places. Sandlake. June and July. 



This species has a peculiar odor resembling that of chloride of 

 lime. In this respect it is similar to some species of Mycena. The 

 plant is quite variable. The disk of the pileus is now elevated, now 

 depressed, sometimes darker than the rest, sometimes canescent with 

 short, grayish fibrils. The margin is quite thin and sometimes stri- 

 atulate when moist. Occasionally it surpasses the lamellae, which in 

 the expanded plant are often ventricose. The stem is sometimes 

 irre2;ular or compressed. The species belongs to the section Te- 

 PHROPHAN^, and is apparently allied to A. laceratus. 



Lieptonia albinella. 



Pileus submembranous, subconieal or convex, subumbilicate, fur- 

 furaceous or minutely squamulose, hygrophanous, whitish and stri- 

 atulate on the margin when moist, white and shining when dry ; 

 lamellffi narrow, close, adnexed, white, becoming incarnate ; stem 

 equal, hollow, glabrous or slightly pruinose, whitish ; spores angular, 

 .00045 to .0005 in. long, .0003 to .00035 in. broad. 



Plant 1.5 to 2 in. high, pileus 6 to 12 lines broad, stem 1 line 

 thick. 



Bushy places. Sandlake. July.
