74 AGARICINI. 



stem. Veil woven into a web, which adheres to the margin of 

 the pileus. Pileus fleshy, margin at first incurved. Gills 

 adnate or sinuate. Hypholoma correspond with Tricholoma, 

 Entoloma, and Hebeloma. 



H. perplexutn. Pk. 



Pileus, convex, fleshy, expanded, light, brown with a pale 

 yellow margin, disk reddish. 



Gills, rounded, sinuate, easily separating from the stipe, 

 pale yellow, greenish cinereous, finally purple brown. 



Stem, subequal, firm, fibrillose, hollow, yellow reddish at 

 the base, light brown. 



The H. fascicularis and sublateritius are almost similar 

 species, with very little difference, and are nearly related 

 species. 



This is called the troublesome agaric or toadstool owing to its nearly 

 related character to the European H. fascicularis. During the autumn 

 nearly every stump is surrounded by clusters of it, and even as late as 

 December you can find fully developed plants. It is easily recognized 

 by its olive greenish gills and brownish yellow top. The young plant 

 has a spider-web veil. It is no doubt poisonous. I have seen no record 

 of its properties, and I am slow in testing its qualities. 



Common on oak stumps throughout the Lehigh Valley late in fall. 



H. ornella. Pk. 



Pileus, convex, pale yellow, with darker scales, with a 

 thin veil attached to margin ; margin thick entire. 



Gills, emarginate, yellowish at first, then dark purple from 

 the spores. 



Stem, crooked, smooth, solid. 



Scarce in chaparral woods. Near Cedar Creek. 



H. appendiculatus. Bull. 

 Pileus, thin ovate, expanded, watery, when dry covered
