of an ivory comb," decurrent from tlie shape of tlie pileus, 

 Tvhen bruised changing to nmber. Stem 1-3 in. high, 

 1^2 in. thick, often compressed, minutely pruinose, solid 

 but spongy withiD, the substance breaking up into transverse 

 cavities. (Berk.)

White. Pileus 4-8 in. across, ilesh thick, firm ; convex 

 then expanded and umbilicate, tomentose, not zoned ; gills 

 decurrent, 2 lines broad, distant, arcuate, not forked but 

 connected by branches; stem 2-3 in. long, up to 1^- in. 

 thick, downy, solid ; spores very minutely asperate, 8-6 /x ; 

 milk scanty, white unchangeable, acrid.

The pileus is sometimes very broadly umbilicate or cup- 

 shaped, at others almost flat. Milk sometimes absent. Very 

 closely resembling Hussula delica but distinguished by the 

 floccose or downy pileus and acrid taste. 



Large, hard, rigid, milk very acrid, scanty, white. Stem 

 stout, solid, equal, 2-3 in. long, 1-1^- in. thick, with delicate 

 innate down on the surface. Pileus fleshy, compact, convex 

 then flattened, margin for a long time bent down, 5-7 in. 

 broad, innatelj^ dowmy, dry, zoneless, wdiite, with sugges- 

 tions of reddish tan. Gills arcuate, adnato-decurrent, 

 thickish, margin acute, rather distant, 2 lines and more 

 broad, connected by branches (but not dichotomous), pallid, 

 w^atery white. Closely allied to L. ])iperatus, differing in 

 certain points, more especially in the broader, arcuate, 

 somewhat distant gills. The milk sometimes becomes pale 

 sulphur-colour when the flesh is broken, but soon changes 

 to w^hite. (Fries.) 



Pileus 4-7 in. broad more or less infundibuliform, the 

 whole surface minutely but densely tomentose ; white, firm, 

 fleshy ; margin at first involute. Milk w^hite, acrid. Gills 

 white, narrow (but occasionally broad and brittle, like A. 

 exsuccus), distant, forked, connected by veins, at length 

 slightly buff or yellowish, rufescent after being bruised. 

 Stem 1 in. high, 2 in. thick, blunt, rather less downy than 

 the pileus, solid. (Berk.)
