THE RUSTY-SPORED AGA RICS 263 



The stem is stuffed, then hollow, colored as the pileus, nearly smooth, ring 

 thin but entire. 



They are a late grower and found on well-decayed logs. They are quite com- 

 mon in our woods. Found in November. The plants in Figure 213 were found 

 on the 24th of November, in Haynes' Hollow. 



Pholiota mutablis. Schaff. 

 The Changeable; Pholiota. Edible. 



Mutablis means changeable, variable. The pileus two to three inches broad, 

 fleshy ; deep cinnamon when moist, paler when dry ; margin rather thin, trans- 

 parent ; convex, then expanded, somestimes obtusely umbonate, and sometimes 

 slightly depressed; even, quite smooth, flesh whitish and taste mild. 



The gills are broad, adnate, slightly decurrent, close, pale umber, then cin- 

 namon-color. 



The stem is two to three inches long, slender, stuffed, becoming hollow, 

 smooth above or minutely pulverulent, and pale, below slightly scally up to the 

 ring, and darker at the base, ring membranaceous, .externally scaly. The spores 

 are ellipsoid, 9-11x5-6^. 



I find this specimen growing in a caespitose manner on decayed wood. It 

 is quite common here late in the season. I found some very large specimens on 

 Thanksgiving day, 1905, in Gallia County, Ohio. It is one of the latest edible 

 plants. 



Pholiota hcteroclita. Fr. ' , . 



Bulbous-stemmed Pholiota. 



Heteroclitus means leaning to one side, out of the center. 



The pileus is three to six inches broad, compact, convex, expanded, very 

 obtuse, rather eccentric, marked with scattered, innate, adpressed scales, whitish 

 or yellowish, sometimes smooth when dry, viscid if moist. 



The gills are very broad, at first pallid, then ferruginous, rounded, adnexed. 



The stem is three to four inches long, solid, hard, bulbous at the base, 

 fibrillose, white or whitish ; veil apical, ring fugacious, appendiculate. The spores 

 are subelliptical, 8-10x5-6/*,. 



This species has a strong and pungent odor very much like horse-radish. 

 It grows on wood and its favorite hosts are the poplar and the birch. It is 

 found at almost any time in the fall. The specimens in the Figure 214 were 

 found in Michigan and photographed by Dr. Fischer, of Detroit.
