LACTARIUS. 103 



'what distant, rather broad (4 mm., 2 lin. and more), connected by Lactarius. 

 branches (but not dichotomous), pallid, watery white. Milk 

 white, scanty, very bitter. 



Large, hard, rigid. The pileus tends to become pallid reddish-tan. Very 

 much allied to L. piperatus. On being broken it sometimes changes to pallid 

 sulphur-yellow, but after a time becomes white again. Easily confounded 

 with Russula delica. 



In woods. Common. Sept.-Dec. 



Spores hardly echinulate, 4 x 8 mk. W. G.S. Name vellus, fleece. From

23. L. exsuccus Smith. Pileus clothed with adpressed down, 

 fleshy, depressed, with an involute margin. Stem very short, 

 white, clothed with adpressed down. Gills decurrent, con- 

 nected by veins, and forked, white, shaded with verdigris. 



Whole plant rigid and brittle, milkless. 

 In woods. Uncommon. 



Considered by some to be a var. of L. vellereus. It must be regarded as a 

 distinct species, but I retain it among Lactarii only in deference to the 

 opinion of others. Spores covered with spines, almost globular, 9 mk.
