under the microscope, strongly echinulate or tuberculate, globose, 

 6-10 //. The stem is usually paler than the pileus, firm, stuffed. 

 The milk is white, slowly acrid to the taste.

Lactarius gerardii Pk. — This plant was described by Dr. Peck in 

 the 26th Report, N. Y. State Mus., p. 61;, and in the 28th Rept. p. 

 129. According to the de- 

 scriptions it differs from Lac- 

 tarius fii/iiiinosiis only in the 

 spores being white, the gills 

 more distant, and the taste 

 being constantl\' mild. Since 

 the taste in /.. fii/ioiiiosiis is 

 sometimes mild, or slowly 

 acrid, and the lamelki' in the 

 older plants are more distant, 

 the spores sometimes only 

 tinged with yellow, there 

 does not seem to be a very 

 marked difference between 

 the two species. In fact all 

 three of these species, /////>/- 

 710SIIS. ligiiyotis and gerardii 

 seem to be very closely re- 

 lated. Forms of fiiligiiiosus 

 approach lionyottis in color, 

 and the pileus sometimes is 

 rugose wrinkled, while in //;'- 

 nyofits pale forms occur, and :| S- 

 the pileus is not always «'§ 

 rugose wrinkled. The color Z c 

 of the bruised lamelhf is the 

 same in the two last species 

 and sometimes the change in 

 color is not mark'ed. 



Lactarius torminosus (Schaeff.) Fr. — This plant is widel\" distribu- 

 ted in Europe, Asia, as well as in America. It is easily recognized 

 by the uneven mixture of pink and ochraceous colors, and the very 

 hairy or tomentose margin of the cap. The plants are 5-10 cm. high, 

 the cap about the same breadth, and the stem 1-2 cm. in thickness. 

 It occurs in woods on the ground during late summer and autumn.
