Iieucosporee 



cheesy, white, commonly reddish beneath the separable pellicle. Stem Russuia. 

 23 in. long, as much as I in. thick, spongy-stuffed, but firm, often 

 cavernous within when old, equal, smooth, even, shining white. Gills 

 rounded behind, connected by veins, not much crowded, broad, forked 

 with shorter ones intermixed, shining white. 



Allied to R. vesca in its mild, pleasant taste and in other respects, 

 but constantly different in the color of the pileus, which is very variable, 

 whereas in R. vesca it is unchangeable. The peculiar combination of 

 colors in the pileus, though very variable, always readily distinguishes 

 it. Fries. 



Spores 8 9/i, cystidia numerous, pointed, Massce; 8 10x6 8/A Sacc. 



In mixed woods. Common. August to October. 



Pronounced one of the best esculent species by all authorities. 



R. heterophyl'la Fr. Gr. differing; Gr. a leaf. (Gills differing 

 in length.) Pileus very variable in color, but never becoming reddisJi 

 or purple, fleshy, firm, convexo-plane then depressed, even, polished, 

 the very thin pellicle disappearing, margin thin, even or densely but 

 slightly striate. Flesh white. Stem solid, firm, somewhat equal, even, 

 shining white. Grills reaching the stem in an attenuated form, very nar- 

 row, very crowded, forked and dimidiate, shining white. 



Taste always mild, as in R. cyanoxantha, from which it differs in its 

 smaller stature, in the pileus being thinner, even, never reddish or pur- 

 plish, with a thin closely adnate pellicle, in the stem being firm and solid, 

 and in the gills being thin, very narrow, very crowded, etc. The apex 

 of the stem is occasionally dilated in the form of a cup, so that the gills 

 appear remote. Fries. 



Spores echinulate, 5x7^ W.G.S.; 7-8/* diameter Massee. 



Common. Woods. July to November. 



Edible, of a sweet nutty flavor. Stevenson. 



R. heterophylla is very common. Its smooth, even pileus, colored in 

 some dingy shade of green, distinguishes it. It is much infested by 

 grubs. Specimens for the table should be young and fresh. Wilted 

 specimens are unpleasant. 



R. foe'tens Fr. fcetens, stinking. Pileus 4-5 in. and more broad, 

 dingy yellow, often becoming pale, thinly fleshy, at first bullate, then 

 expanded and depressed, covered with a pellicle which is adnate, not
