Spores globose, rough, 7.5 to 10 /t. Pileus 12 mm cm. 



broad; stem 2.5 to L5 cm. long. 



Common in woods throughoul our district. Vcr lu 

 during the rainy season of L902. Specimens were often 

 measuring up to 8 cm. in diameter. Depauperate pi 

 found in moist places; these having the pileus only 1 to 6 

 broad. These appear at first sighl to be a differenl spccii 

 conned with the ordinary form by insensible gradations. I 

 minute plants are usually densely gregarious. 



Clitocybe amethystina Bolt. 



Pileus dark-purple, umbilicate, smooth, minutely tour i 

 involute. 



Lamellae dark-purple, broad, decurrenl . 



Stem fibrillose, purple, streaked with white fibrils, equal, 

 densely covered with white tomentum at the base. 



Pileus 2.5 to 3.5 cm. broad; stem, 5 to 7.5 cm. lonj

 distinguishable from those of ( '. laccata, of winch it is considered a 

 variety, although the distinctive amethystine color a] con- 



stant, both in the fresh and dried plant-. 



Clitocybe ochropurpurea 15. & C. (Plate III. Fig. 2 



Pileus subhemispheric, at length depressed, fleshy, compi 

 tough, pale alutaceous, slightly turning to purplish, the cuticle 

 easily separable, the margin inflexed, a1 first tomentose. 



Lamellae thick, purple, broader behind, decurrent. 



Stem paler than the pileus, here and there purplish, tumid in 

 the middle. 



Pileus 2 cm. broad; stem 6 cm. long, 18 mm. thick in the 

 middle. 



Dry woods, Winfield and Lombard, summer and aut limn, 1 S 

 and 1902. The species was common. During L899, 1900 and 

 1901 no plants were found, although careful search was made 

 both stations. 



Well grown specimens have a symmetrically-shaped pileus 7 



to 10, sometimes as much as 15 cm. in diameter. When old, t 

 margin is occasionally rimose, and the whole surface of the pileus 

 broken up into large scales. The cap is often covered with 1 

 abundant spores shed from adjacent or overlying plant- Dis- 

 torted specimens arc common; sometimes with a fusiform stem 

 2.5 to 3.5 cm. in diameter in the middle, and tapering toward the 

 apex and base, and with a pileus not more than 2.5 cm. across 

 other times with a tall, cylindrical stem, or with a club-shaped 

 stem broadening out at the apex into a pileus which is 

 more than a border, indistinctly differentiated into gills upon i 

 under surface; while still others have the stem curiously cun 

 or twisted.
