rolled at first, not striate or crenate, surface smootli, dull, slightly 

 viscid when damp ; color pinkish-tan or avellaneous to wood-brown all 

 over or the center darker or mottled with brick-color. Flesh 2-3 mm. 

 thick, tinted like the cap, rather brittle, not changing when bruised ; 

 odor faint but usually distinct, rather like dried apples, not stronger 

 on drying. Milk white or watery-white, not abundant, mild on first 

 tasting, then moderately and slowly acrid. Said to be mild or bitter- 

 ish at times. 



Gills crowded or scarcely crowded, adnate or slightly decurrent, 

 none or a few forked, veined, 3-5 mm. wide, color of the cap or paler 

 in youth, darker with age, on drying becoming very white-glaucous. 



Stem 1-4 cm. long, 3-7 mm. thick, nearly equal, often compressed, 

 color of cap, smooth, the base coarsely tomentose when in leaves, dis- 

 tinctly hollow except when young. 



Spores (of No. 3019) white, tuberculate, 6-6.8 x 7.5-9. 3/x. 



By the glabrous cap, brownish color of all parts, tardily acrid milk 

 and hollow stem this species may be distinguished. The milk is said 

 to be mild at times. From Miss Burlingham's description our plants 

 differ only in the slightly but distinctly viscid and non-papillate cap. 

 The spores are exactly those of plants from Miss Burlingham, and the 

 dried plants look alike. This is true, however, of L. camphoratus 

 also, plants of which from Miss Burlingham having spores just like 

 those of her L. subdulcis. In fact, no difference appears in the dried 

 plants of the two species, the odor being the same so far as I can 

 detect. From descriptions practically no difference appears except 



that is very different. Lactarius griseus may also grow on decaying logs, but 

 we have found it only on earth in Chapel Hill. The description of our plant 

 follows: 



Cap only 2-3 cm. wide, glabrous, not viscid, depressed in center, light ochra- 

 ceous-buff to ochraceous-tawny. Flesh thin, firm, fragile, with a light tint 

 of the cap color; odor none. Milk mild, sometimes so sparse as to be scarcely 

 discernible even in very young plants. 



Gills close, slightly decurrent, white then tan, with a tint of flesh color. 



Stem very long and slender, 3-7 cm. long and about 5 mm. thick, ochraceous- 

 tawny, lightly stuffed, base distinctly white villous, the hairs turning ochra- 

 ceous-tawny in drying like the stem. 



Spores white, spherical, a few short-elliptic, warted, 5.9-8.5 x 5.9-10.2^. Dis- 

 tinctly more spherical than in L. subdulcis, Nos. 3019 and 3040.
