 p. 313 ; Cke., Illnstr., pi. 1009b, and 1085. 



On damp gronnd nnder birches, &c. 



Growing in troops, generally very slender and small, \mt 

 mixed ■svith larger, firmer, and darker specimens. Allied to 

 L. rieius, but distingnished by its size and slender bnild ; 

 milk ■white and nnchangeable when the gills are ■wounded ; 

 smell at first scarcely e"vident; but strong and like bugs 

 ■when half dry. (Fries.) 



** Impoliti. 



Lactarius (Russ.) rufas. Scop. 



Pileus 3—4 in. across, flesh rather thin, 'pallid ; umbonate 

 ■when yuung, soon depressed and at length infundibuliform, 

 the umbo persistent at base of the depression, entirely 

 zoneless, dry, floccosely silky at first but soon polished, 

 glabrous, rather polished and shining, rufous-bay, rufous- 

 cinnamon ■when old; margin incurved and covered ■with 

 "whitish down, "when young ; gilLs adnately decurrent, 

 crowded, about 1 J line broad, scarcely branched, ochraceous 

 then pale rufous ; stem 2—3 in. long, about J in. thick, eqaal, 

 nifescent, but paler than the pileus, base ■with ■white down, 

 indistinctly pruinose or quite glabrous, stufied, rather 

 fragile; milk white, unchangeable, intensely acrid; spores 

 echinulate, 9 x T /x. 



Lactarius rufas, Scopoli, Cam., iL 451 ; Cke., Hdbk., p. 314 ; 

 Cke., Blustr,, pL 985. 



In dry pine woods. 



Differs from every other species included in the section 

 Snssulares in the margin being clothed ■with whitish down 

 and incurved ■when young. The pileus although minutely 

 flocculose at fir^t, is soon glabrous and shining. A small 

 form of ■the present species often very much resembles L. siib- 

 dulds, from ■which it is distinguished by the very acrid taste.
