to three-fourths of an inch in thickness. It is firm and solid at 

 first, becoming somewhat pithy at maturity. It is usuallv of a 

 uniform thickness, but may taper somewhat towards the base. It 

 is colored like the cap, although frequently it is a lighter shade 

 of brown. This is considered by the writer the most delicious 

 species belonging to the genus. 



Lactarius corrugis Pk. is not distinct in many characters 

 from L. z'olemns. Somewhat larger in size, the cap is of a 

 darker shade of brown; the surface is usually more deeply 

 corrugated, and the young specimens are covered with a close 

 pubescence which gives the cap a velvety appearance in the sun- 

 light. This plant has similar habitats to L. volemus, and the two 

 plants have been found within a few feet of each other. 



Lactarius piperatus (Scop.) Fr., Peppery Lactarius (Plate 

 IX, Bull. No. 3), is another exceedingly common species. It 

 grows in open woods in similar places to the other Lactarii. Its 

 pure white color serves to make it a conspicuous object in the 

 leaf-mold. Sometimes the cap does not appear above the sur- 

 face, especially if the leaf-mold is thick, and the presence of the 

 fungus is recognized only by an elevation of the leaves. The 

 species is characterized by its pure white color, its thick fleshy 

 cap, which becomes more and more funnel-shaped as it expands, 

 its thick stem, and very close, narrow gills. This last feature 

 serves to separate the species from Lactarius dcccptivus, which 

 it resembles. L. deceptivus has more distant, coarse gills. The 

 gills in L. piperatus are more or less forked or divided into pairs. 

 The milk is exceedingly acrid in young specimens. It is white 

 and unchangeable when exposed to the air. This species is 

 frequently gathered and eaten by the students of the Connecticut 

 Agricultural College for their " steak and mushroom spreads." 

 It loses its peppery character in cooking. 



Lactarius deceptivus Pk. (Plate VIII, Bull. Xo. 3) is closely 

 related to L. piperatus, from which it may be distinguished by a 

 dense, wool-like growth of hairs along the inrolled margin of 

 the cap, and by its coarse, distant gills. The cap varies from 

 three to six inches in diameter, and in some cases the writer has 

 seen specimens even eight inches across. It grows in similar 

 localities with L. piperatus. The flesh is white and coarse in 

 texture; milk white, unchangeable, with an acrid taste. The
