GENERA AND SPECIES OF MUSHROOMS 



Stem cylindric; solid; firm; paler than the cap; 4 to 6 

 inches long. 



Spores white; large; nearly globular; .00045 to .0005 inch 

 in diameter; with small needle-Hke points, .0016 to .002 inch 

 long. 



This remarkable species resembles Lactarius volemius. It 

 is, however, of a darker color and the surface of the cap is 

 very uneven from the presence of folds which present an 

 appearance much like that of the hymenium (spore-bearing 

 surface) of some species of Merulius (a fungus having a 

 network of pits or pores, instead of gills). The spicules 

 (little spikes) on the gills too, are a peculiar feature of Lactarius 

 corrugis. They are so numerous that under a lens they give 

 a hairy appearance to the edge of the gills. Peck. 



Dr. Murrill considers that this species is the most common 

 of the milk-bearing mushrooms (Lactarius). 



Lactarius deliciosus; delicious lactarius; orange-milk 

 lactarius. Plate XI, Species 73. 



On ground in woods, groves and in mossy swamps; odor 

 not marked; taste often slightly acrid; orange-colored milk 

 exudes when the plant is broken. Wounded places slowly 

 become greenish; July to October; edible. 



Cap broadly convex when the plant is young; centrally 

 depressed or funnel-shaped when mature; smooth; moist; 

 yellowish, with circles or mottled zones of deeper hues; 

 flesh whitish, stained with orange in the part nearest to the 

 gills; 2 to 5 inches broad. 



Gills orange-colored, but clearer than the cap; attached to 

 the stem or extending down the stem (adnate or decurrent). 



Stem smooth; short if growing from the ground, longer if 



growing among mosses; sometimes tapering toward the base; 



with the color of the cap or paler, sometimes with a few bright 



orange spots; i to 4 inches long, Vs to V3 of an inch thick.
