B. Milk colored from the first. 



9. L. DELicioscS; Linn. — Pilciis fleshy, convex, umbilicate, viscid, 

 zonatc. ghihious, soniewliat orange-color, expallent, the margin 

 glabrons. Slipe stuffed, Ihcn hollow, spotted. LamellfE somewhat 

 dccurrcnt, snnVon-color, hut expallent and greenish when wounded; 

 the milk aromatic, safl'ron-red. 



In damp woods. Pileus 34 in. broad, stipe 1.^-3 in. long. The 

 whole plant abounds with orange milk, and when bruised or old ex- 

 hibits stains of green. 



C. LameJlcE pallid then chamjinrj to a darker color, finally 

 white-pruinose ; milk white, 

 d. Pileus viscid from the first.

 depressed, usually umbilicate, glabrous, viscid, light gray, with the 

 disk sometimes a little darker. Stipe tapering upward, stufl'cd, con- 

 colorous. Lamcllne close white; the milk while acrid. 



In woods. Pileus 1^-3 in. broad, stipe 2 4 in. long. This seems to 

 be a larger plant than Prof. Peck's, and I often find the pileus zonate, 

 3'et it does not seem to me to differ sufficiently to make a new species. 



11. L. viETUS, Fr. — Pileus fleshy, thin, at first somewhat umbonate, 

 viscid, afterward applanate, umbilicate, even, not zonate, when dry 

 finely silky, expallent. Stipe stufl'cd then hollow, fragile, livid. 

 Lamclljc somewhat decurrent, thin, whitish ; milk at first white then 

 changing to gray, tardily acrid. 



In humid woods. Pileus 2-4 in. broad, stipe 2 3 in. high. A verj' 

 distinct species, thin, sol't, fiagile and various in form; the pileus 

 Bomctimes infundibnlifoim, flesh-color or livid then gray. 



c. J'ilois scaly, villoits or pritinose. 



12. L. KisTANS, Peck. — Pileus fleshy, linn, convex or expanded, de- 

 pressed, pniinose-lomciitoso, ycllowisli-tawny. Stipe very short, solid, 

 firm, equal or tapering downward, prninoso, nearl\ of the color of the 

 pileus. Lanu'llii; distant, somewhat arcuate, white or yellowish; 

 milk white, mdd. 



In grassy ground. Pileus 2-4 in. lirond, stipi; 12 in. high. The 

 pileus is sometimes irregular and excentric, and the cuticle often 

 cracks into areas.
