The pileus varies in size from about 7.5-30 cent. (3-12 in.) Spores Lactarius. 

 sphaeroid or subsphoeroid, uniguttate, echinulate, 6-8 mk. K. Nameturpis,

5. L. controversus Fr. Pileus 7.5 cent. (3 in.) and more 

 broad, fleshy, compact, rigid, at the first convex, broadly umbili- 

 cate, when fuller grown somewhat infundibuliform, oblique, on 

 emerging from the ground dry, flocculose, whitish, then with 

 rain smooth, viscid, reddish, with blood-coloured spots and zones 

 (especially towards the margin), margin acute when young, 

 closely involute, more or less villous ; flesh very Jinn. Stem 

 commonly 2.5 cent, (i in.) long and thick, sometimes however 

 5 cent. (2 in.) long and then manifestly attenuated towards the 

 base and often excentric, solid, obese, even but pruinate and as 

 if striate at the apex from the obsoletely decurrent tooth of the 

 gills, wholly white, never pitted. Gills decurrent, thin, very 

 crowded, 2-4 mm. (1-2 lin.) broad, with many shorter ones inter- 

 mixed, but rarely branched, pallid - white -flesh - colour. Milk 

 white, unchangeable, plentiful. 



Odour weak but pleasant, taste very acrid. Allied to L. piperatus. 

 In woods. Uncommon. Aug.-Oct.

 turn. From its becoming at length infundibuliform. Fr. Monogr. ii. p. 155.

6. L. pubescens Fr. Pileus about 5 cent. (2 in.) broad, 

 whitish passing into flesh-colour, fleshy, rather plane, depressed 

 in the centre, then broadly infundibuliform, quite zoneless, even, 

 dry, becoming smooth at the disc, shining, margin involute, 

 fibrilloso-pubescent; flesh thin but firm, pliant, white, or flesh- 

 coloured in the cuticle, unchangeable. Stem short, scarcely 

 2.5 cent, (i in.) long, 12 mm. (}4 lin.) thick at the apex, attenuated 

 downwards and sometimes compressed, stuffed, soft internally, 

 even (not pitted), commonly pruinato -pubescent when young, 

 but commonly becoming smooth, flesh-colour then white. Gills 

 adnate or slightly decurrent, crowded, quaternate, narrower than 

 the flesh of the pileus, pallid, slightly flesh-coloured. Milk white, 

 unchangeable, not plentiful. 



Inodorous, taste very acrid. It is like a poor form of L. controversus, but 

 is very distinct.
