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

 Bdbk., p. 318; Cke., lUustr., pi. 986A. 



On the ground. 



Stem usually thinner at the "base, curved, sometimes 

 excentric. (Fries.) 



Odourless when fresh, but with a strong unpleasant smell 

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

 like inelilot 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 hollow, paler than the pileus; spore globose, 

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



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

 p. 318; Cke., Illustr., pi. 1014A. 



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. 

 The present is also much smaller than either of the above. 



Far. crenatus, Massee. 



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

 coarsely and regularly sulcate, which causes the margin to 

 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 warted, 

 7-8 fj. diarn., 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 at least as a variety in the coarsely sulcate
