Lactarius subumbonatus, Lindgr., Bot. Not., 1845; Cke., 

 Hdbk., p. 318; Cke., Illustr., pi. 986a. 



On tlie ground. 



Stem usually thinner at the base, curved, sometimes 

 ■excentric. (Flies.) 



Odourless when fresh, but with a strong unpleasant smell 

 when dry. L. camphoratus differs in having a pleasant smell 

 like melilot when dry, also scentless when fresh. L. cimi- 

 carius differs in the absence of an umbo, in having an un- 

 pleasant smell resembling bugs when fresh, but without 

 smell when dried. 



Lactarius (Russ.) obnubilus. Lasch. 



Pileus about 1 in. across, rather fleshy ; convex and usually 

 papillate at first then rather broadly umbilicate, glabrous, 

 slightly striate, zoneless, sooty-brown ; margin slightly 

 arched; gills narrowed behind, adnexed, rather crowded, 

 becoming yellowish at maturity; stem 1-1 1 in. long, 2-3 

 lines thick, slightly thickened at the base, smooth, even, 

 stuffed then hoUow, paler than the pileus; spore globose, 

 echinulate, 8 /t ; milk persistently white, slightly acrid. 



Lactarius obnubilus, Lasch, Linn., n. 71 ; Cke., Hdbk.,

In woods. 



Differs from L. fuliginosus in the milk remaining persist- 

 • ently white ; from L. picinus in the pileus not being velvety ; 

 and from L. retisporus in the spores not being reticulated. 

 ^he present is also much smaller than either of the above. 



Var. crenatus, Massee. 



Pileus 1-2 in. across, convex then depressed, sooty-brown, 

 coarsely and regularly sulcate, which causes the margin tf) 

 be crenate ; flesh thin ; gills rather close, yellowish, broadly 

 adnate with a tendency to become decurrent; stem about 

 1 in. long, \ in. thick, equal, solid at first, becoming im- 

 ' perfectly hollow, smooth, even, paler than the pileus, usually 

 incurved at the base; spores globose, minutely war ted, 

 7-8 /* diam., cystidia absent ; milk persistently white, very 

 slightly acrid. 



On the ground in fir woods. 



Possessing many points in common with L. obnubilus, but 

 very distinct af least as a va,riety in the coarsely sulcate
