Pileus broadly convex, expanded or subinfundibuliform, compact, 

 subglabrous, even or somewhat scabrous-pustulate, tvhite or whitish, 

 the involute maro:in often tomentose-hairv, flesh white : lamellae 

 close, forked, crisped near the stem, adnate or decurrent, vjJiite, then 

 odtraceous-yelloio tinged loitk salmon color ; stem central, short, firm, 

 equal, stuffed or holloiv, pubescent, white ; spores pale ochraceous- 

 yellow, subglobose or broadly elliptical, .0002 to .0003 in. long, .0002 

 in. broad.

 thick.

A large species externally XQtiCiwhXmg Lactarius vellereus, and per- 

 haps hitherto confused with it, but easily distinguished from it by the 

 absence of a milky juice and by the lamellne which are crisped near 

 the base and which soon assume a peculiar salmon-yellow hue, Avhich 

 also appears in the spores when collected on white paper. This 

 change of color begins in the crisped portion near the stem and gradu- 

 ally advances toward the outer extremity. In the dried specimens the 

 lamellffi are ochraceous-brown and they have the edge more or less 

 beaded with white granules. They are often forked near the outer 

 extremity as well as toward the inner. The length of the stem some- 

 times scarcely exceeds its breadth. In l)ut a single instance was it 

 eccentric, and in that case the pileus was lobed and irregular. The 

 surface of the pileus is sonietimes roughened with minute pustules or 

 papilke and sometimes has a pitted appearance. Rarely the margin 

 is obscurely zonate. The taste is bitterish and unpleasant, and some 

 times the plant emits a subacid odor. It is a singular species.
