23. R. heterophylla Fr. Pileus very variable in colour, but 

 never becoming reddish or purple, fleshy, firm, convexo-plane then 

 depressed, even, polisJied, the very thin pellicle disappearing, 

 margin thin, even or densely but slightly striate ; flesh white. 

 Stem solid, firm, somewhat equal, even, shining white. Gills 

 reaching the stem in an attenuated form, very narrow, very 

 crowded, forked and dimidiate, shining white. 



Taste always mild, as in R. cyanoxantha, from which it differs in its 

 smaller stature, in the pileus being thinner, even, never reddish or purplish, 

 with a thin closely adnate pellicle, in the stem being firm and solid, and in 

 the gills being thin, very narrow, very crowded, &c. The apex of the stem 

 is occasionally dilated in the form of a cup, so that the gills appear remote.

* R. galochroa Fr. Smaller. Pileus at the first milk-white, 

 then greenish, rather plane, viscid in wet weather, commonly 

 dry, even, sometimes sprinkled with white floccose spots, slightly 

 striate at the margin. Stem 2.5-5 cent. (1-2 in.) long, 12 mm. 

 (}4 in.) thick, solid, firm, never becoming red. Gills very thin, 

 more or less forked and unequal. 



The flocci at the disc in the form of spots or warts are not like those of 

 R. virescens. Tn woods. Slough. Name yd\a, milk ; xp^s, colour. Milk-

24. R. consobrina Fr. Pileus 7.5 cent. (3 in.) broad, dark 

 cinereous or fuscous olivaceous, fleshy, fragile, campanulate then 

 expanded, at length depressed, margin spreading, even, though 

 membranaceous ; flesh white, cinereous under the thick, viscous, 

 separable pellicle. Stem 5-7.5 cent. (2-3 in.) long, almost 2.5 

 cent, (i in.) thick, solid, but soft, equal, even, smooth, shining 

 white, at length becoming cinereous. Gills at the first free, then 

 appearing adnate when the pileus is flattened, broad, crowded, 

 shining white, very many of them dimidiate and forked. 



Taste very acrid. Not foetid. Stature in general that of R. emetica, but 

 differing in the colour of the pileus, and in the very unequal gills.
