from dilute or sordid purplish becoming yellowish, often plicate striate 

 to the middle. 



10. R. LUTEA, Vent. — Mild. Pileus a little firm, piano depressed; the 

 cuticle viscid, expallent; the flesh white; the margin even. Stipe 

 stufFc'd then hollow, soft, while. Laraellje narrow, free, close, venose- 

 connected, e.i2g-yellow. Spores yellow. 



In beech woods. Pileus lA-2^ in. l)road, stipe l-l^ in. long. An 

 elegant plant; pileus from a beautiful yellow becoming pale. The 

 plant I have so referred has the lamellae at first white and the stipe 

 yellow like the pileus; it may be a new species. 



Note. — The Russulre form a very natural assemblage related to Lac- 

 tarii, but differing from thcni in tin- absence of the milk}' jnic-e. lUit 

 various Russulae exude dro|)s of water, especially in wet weather. The 

 species arc quite dillicult of determination, particularly on account of 

 their variable colors. 



Genus IX. — Cantharellus, Adans. 



Ilymenophore contiguous with the stipe, descending unchanged into 

 the trama. Lamellne thick, fleshy-wax^^ in the form of folds, somewhat 

 brancljcd, the edge obtuse.

1. C. ciBAiaus. Fr. — Egg-yellow. Pilous fleshy, firm, at first repand, 

 glabrous, at length turi)iiiate. Stipe solid, tapering downward. Lam- 

 elhc thick, distant, concolorous. Spores white, oval, .OOTOx-OOaO mm. 



In woods. Pileus 1 :'. in. broad, stipe 12 in. long, and about \ an 

 inch thick. This is the famous C'liantrclle, esteemed as a delicacy 

 from the most ancient times. It is not common with us; but is oc- 

 casionally met with along wiih its not distant relative Cmterellus 

 lalcviliiis, Ik'rk. Tiie latter is distinguislied from the former by the 

 hymenial surface l)eing even i)V merely wrinkled, not lamellose. 



2. C. MiNoK, Peck. — Pileus fleshy, thin, convex, then expanded and 

 depressed, egg-yellow. Stii)e slender, subllexuous, equal, smooth, 

 stuJb'd or hollow, concolorous. LamelliP very narrow, distant, sparingly 

 branched, yellowish. Spores white, .007x-0" 1 mm. 



On the ground in open wood.«. I'ileus 1 2 in. broad, stijie 1-2 in. 

 long. My specimens are rather of a brownish yellow. The i)ileus is 

 much thinner, and the stipe more slender th:in in C cibarius ; the two 

 arc clearly distinguishal>le.
