122 THIRTY-EIGHTH REPORT ON THE STATE MUSEU™M. 
closely related to L. insulsws, but apparently distinct by its darker 
color, broader, looser lamellz and zoneless pileus. It appears to be in- 
termediate between that species and L. hysginus. 
Lactarius insulsus, /7. 
Unsavory Lactarius, 
Agaricus flecuosus, Secr. 
Pileus convex and umbilicate, then infundibuliform, glabrous, viscid, 
more or less zonate, yellowish, the margin naked; lamelle thin, close 
adnate or decurrent, some of them forked at the base, whitish or pallid; 
stem equal or slightly tapering downward, stuffed or hollow, whitish or 
. yellowish, generally spotted ; spores .co03 to .00035 in.; milk white, 
taste acrid. . 
Pileus 2 to 4 in. broad, stem 1 to 2 in. long, 4 to 6 lines thick. 
Thin woods and open, grassy places. Greenbush> and Sandlake. 
July and August. ¥ 
Our plant has the pileus pale yellow or straw color, and sometimes 
nearly white, but European forms have been described as having it 
orange-yellow and brick-red. It is generally, though often obscurely, 
zonate. The zones are ordinarily more distinct near the margin, where 
they are occasionally very narrow and close. The wilk in the Green- 
bush specimens had a thin, somewhat watery appearance. Authors dif- 
fer in their estimate of its qualities, some affirming that it is edible, 
~ others that it is poisonous. It is classed as edible in the Curtis Cata- 
logue, and Cordier says that it appears to be edible. 
* Lactarius cinereus, Peck. 
Cinereous Lactarius. 
Pileus thin, nearly plane and wmbilicate or subinfundibuliform, 
glabrous, viscid, pale gray or cinereows, the disk sometimes darker col- 
ored ; lamelle narrow, close, white ; stem equal or slightly tapering up- 
ward, stuffed, sometimes tomentose at the base, colored like the pileus ; 
spores white, .coo28 to .coo3 in.; milk white, taste acrid. 
Pileus 1 to 2 in. broad, stem 1 to 3 in. long, 3 to 4 lines thick. 
Woods. Sandlake and Greig. August and September. 
The species is evidently closely allied to L. vietws Fr., but I 
have never seen the pileus umbonate or expallent, nor the milk become 
gray, characters attributed to that species. In our plant the viscid pel- 
licle is separable. In shape and size it resembles L. ¢rivialis v. gracilis, 
but its paler usually umbilicate pileus, concolorous stem and white 
spores separate it. Mr. Morgan finds, in Vermont, a somewhat larger 
form with the pileus sometimes zonate. 
** Pileus not viscid. 
+ Pileus minutely tomentose or squamulose 
Lactarius griseus, Peck. 
Gray Lactarius. 
Pileus thin, nearly plane, broadly umbilicate or centrally depressed, 
sometimes infundibuliform, generally with a small umbo or papilla,
