THE WHITE-SPORBD AGARICS

Tricholoma quinqucpartitum. Vr. 



Quinquepartitum- means divided into five parts. There is no apparent reason 

 for the name. Fries could not identify Linnaeus' Agaricus quinqnepartitus and 

 he attached the name of this species. 



The pileus is three or four inches broad, slightly fleshy ; convex, rather 

 involute, then flattened, somewhat repand ; viscid, smooth, even, pale yellowish. 



The gills are notched at the point of attachment to the stem, broad, white. 



The stem is three to four inches long, solid, striate or grooved, smooth. The 

 spores are 5-6x3-4. 



This species differs from T. portentosum in the pileus not being virgate, and 

 from T. fucatum in the smooth, striate or grooved stem. This plant is found in 

 thin woods where logs have decayed. I have not eaten this species but I have 

 no doubt of its edibility. The taste is pleasant. Found in October and November. 



Tricholoma lateraruim. Pk. 



Laterarium is from later, a brick ; so called because there is nearly always a 

 slight tinge of brick red on the disk. 



The pileus is two to four inches broad, convex, then expanded, sometimes 

 slightly depressed in the center ; pruinose, whitish, the disk often tinged with red 

 or brown, the thin margin marked with slight subdistant, short, radiating ridges. 



The gills are narrow, crowded, white, prolonged in little decurrent lines on the 

 stem. The stem is nearly equal, solid, white. The spores are globose, .00018 

 inch in diameter. Peck's 26th Rep. 



This plant is quite widely distributed in the United States. It is found quite 

 frequently in Ohio and is rather abundant on the hillsides about Chillicothe, where 

 it is frequently somewhat bulbous. The tinge of brownish-red on the disk, and the 

 short radiating ridges on the margin of the pileus will serve to identify the plant. 

 It is edible and fairly good. 

 Found on leaf-mold in rather 

 damp woods from July to No- 

 vember. 



Tricholoma panccolum. Fr. 



Panseolum, all variegated. The 

 pileus is from three to four 

 inches broad, deeply depressed, 

 dusky with a gray bloom, hygro- 

 phanous ; margin at first inrolled, 

 sometimes wavy or irregular 

 when fully expanded. 



The gills are quite crowded, 

 adnate, arcuate, white at first,
