ROSY-SPORED AGARICS. 143 



pressed. It is whitish in color, or dark gray, or with a leaden tint, 

 dry, sometimes with a distinct bloom on the surface, and the margin 

 is often wavy. The cap is sometimes produced more on one side than 

 on the other. The gills are not close, at first whitish, then salmon 

 colored as the spores mature, and they are decurrent as is character- 

 istic of the genus. The spores are elliptical or nearly so, and meas- 

 ure IO-I2 fj. long. 



Figure 138 is from plants collected near Ithaca, in the autumn of 

 1898. This species is considered to be one of the excellent mush- 

 rooms for food. When fresh it has a mealy odor and taste, as do 

 several of the species of this genus. It is known as the prune 

 mushroom. 



Clitopilus orcella Bull. Edible. This plant is sometimes spoken. of 

 as the sweet-bread mushroom. It is much like the prune mushroom 

 just described, in odor and taste, and sometimes resembles it in form 

 and other characters. It is white in color, and the plants are usually 

 considerably smaller, and the pileus is, according to my observations, 

 sometimes more irregular, lobed and wavy on the margin. The flesh 

 is also softer, and the cap is said to be slightly viscid in wet weather. 

 The plant grows in the woods and sometimes in open fields. 



ENTOLOMA Fr. 



The volva and annulus are absent in this genus, the spores are 

 rosy, the gills adnate to sinuate or adnexed, easily separating from 

 the stem in some species. The stem is fleshy or fibrous, sometimes 

 waxy, and the pileus is fleshy with the margin incurved, espe- 

 cially when young. The spores are prominently angular. The genus 

 corresponds with Tricholoma of the white-spored agarics, and also 

 with Heheloma and Inocyhe of the ochre-spored ones. Entoloma re- 

 pandum Bull., is an Inocyhe [/. repandum (Bull.) Bres.] and has 

 angular spores resembling those of an Entoloma, but the spores are 

 not rosy. 



Entoloma jubatum Fr. Growing on the ground in woods. The 

 plants are 5-10 cm. high, the cap 3-6 cm. broad, and the stem 3-6 

 mm. in thickness. 



The pileus is conic in some plants, to convex and umbonate, thin, 

 minutely scaly with blackish hairy scales, dull heliotrope purple, 

 darker on the umbo. The gills are vinaceous rufus to deep flesh 

 color, strongly sinuate, and irregularly notched along the edge. The 

 spores are irregularly oval to short oblong, coarsely angular, with an 

 oil drop, 5-7 angled, 7-1 1 x 6-7 yw. The stem is of the same color as 

 the pileus, sometimes deeply rooting, hollow. Figure 139 is from
