pleasant. Lamellae nearly equal, subdistant, sometimes forked near the Russuia. 

 stem, at first white, then yellowish, becoming brownish where bruised. 

 Stem 2-3 in. long, 5-8 lines thick, equal, glabrous, spongy within, 

 white, brownish where bruised. Spores subglobose, minutely rough, 

 pale ochraceous with a salmon tint, 8-iO/x.

In color this species resembles R. variata, but in other respects it is 

 very different. It is very distinct in the peculiar color of its spores, 

 and in the brownish hue assumed by wounds. Peck, 4ist Rep. N. Y.

 they should be cooked as soon as gathered. Even in wilting they be-

R. aluta'cea Fr. aluta, tanned leather. PileuS 2-4 in. broad, 

 commonly bright blood-color or red, even black-purple, but becoming 

 pale, especially at the disk, fleshy, bell-shaped then convex, flattened 

 and somewhat umbilicate, even, with a remarkably sticky pellicle, 

 margin thin, at length striate, tubercular. Flesh snow-white. Stem 

 2 in. long, solid, stout, equal, even, white, most frequently variegated- 

 reddish, even purple. Gills at first free, thick, very broad, connected 

 by veins, all equal, somewhat distant, at first pallid light yellow, then 

 bright ochraceous, not pulverulent. 



It is distinguished from R. integra by its gills not being pulverulent.

R. alutacea is easily recognized among Russulae by its mild taste and 

 broad yellow gills. In young specimens one sometimes has to look at 

 the gills at an angle to detect the yellow. It is quite common but a 

 solitary grower. It is everywhere eaten as a favorite. Only fresh 

 plants yield a good flavor. When the stem is soft, it should be thrown 

 away.
