II. FURCATVE. 



6. R. furcata Fr. Pileus about 7.5 cent. (3 in.) broad, some- 

 times aeruginous-greenish, sometimes umber-greenish, fleshy, 

 compact, gibbous then piano-depressed or infundibuliform, even, 

 smooth, but often sprinkled with slightly silky lustre, pellicle 

 here and there separable, margin thin, at first inflexed, then 

 spreading, always evenj flesh firm, somewhat cheesy, white. 

 Stem 5 cent. (2 in.) or a little more long, solid, firm, equal or 

 attenuated downwards, even, white. Gills adnato - decurrent, 

 rather thick, somewhat distant but broad, attenuated at both

Taste bitterish. The structure is that of R. sanguined or rubra, not of 

 R. virescens, with which it agrees in colour, but from which it differs in the 

 form of the pileus, in the acute and at first inflexed margin, in the pellicle 

 being separable and not dividing into warts, and in the entire type of the 

 gills.
