3. Lactarius brevipes Longyear. Described in 3d annual repoft of Michigan 

 Academy of Science, 1901, as follows: Pileus 1.5-3 cm., broad, convex when young, 

 becoming plane and depressed, margin inrolled, dry, whitish-pruinose, reddish tan 

 when rubbed, obsoletely zoned, flesh white; gills adnexed, very narrow, pale 

 tawny, thin, sometimes branched. Stem .6-1.3 cm. long, about two-thirds as broad, 

 equal or tapering downward, smooth, white, solid; spores globose, echinulate, 

 6 microns. Milk white, becoming light yellow on exposure to air, slowly acrid and 

 astringent to taste, odorless. Growing on moss-covered ground in oak woods. 

 Pleasant Lake, July 27 and 30, 1900. 



On account of the short stem the pileus appears to rest on the ground. The 

 species seems somewhat closely related to L. thejogalus. Bull, but is much smaller, 

 while the dry instead of viscid pileus and the very short stem serve to distinguish 

 it from that species. 



Lactarius chelidonium Pk. Greenville. Autumn. Barlow. 



Lactarius deliciosus Fr. Found only twice in a mossy swamp. Lewiston, 

 Beardslee. 



Lactarius griseus Pk. On old mossy logs in a cedar swamp. Lewiston, Beardslee. 

 Lactarius distans Pk. Not uncommon in woods. Summer. 

 Lactarius indigo Schw. Woods. Uncommon. Summer and autumn. 

 Lactarius insulsus Fr. Onondaga, August, 1900. Woods. 



Lactarius rufus Scop. Occurred in large numbers in a swamp near M. A. C. 

 during 1898. 

 Lactarius subdulcis Fr. Plentiful in moist and low woods. Summer and autumn. 

 Lactarius subpurpureus Pk. In cedar swamps. Milk dark red. The pileus is 

 a peculiar shade of gray red. Lewiston, Beardslee. 



Lactarius subserifluus Longyear 277. Described in 3d annual report of Mich- 

 igan Academy of Science, 1901, as follows: Pileus 1.5-2 cm., broad, flesh thin, 

 convex or plane, depressed around the papilliform umbo, fulvous or light brick- 

 red, sometimes slightly irregular, dry, glabrous, margin somewhat crenate; gills 

 concolorous. thickish, subdistant, rather broad, adnatodecurrent. Stem 1.5-2.5 

 cm., long 2-3 mm. thick, gradually enlarged toward the base, colored like the pileus, 

 smooth, glabrous, base paler and pruinose, hollow; milk watery like serum, mild, 

 odorless; spores globose, echinulate. 6-8 microns. Growing on naked or mossy 

 soil in upland woods. Leslie, July 24, 1900. 



The few specimens found were growing in company with a small form of L. 

 subdulcis Fr. which the species much resembles and from which it is distinguished 

 by its more distant, broader gills and clear milk. It is closely related to L. serl- 

 fluus Fr., but is separated by its smaller size, umbonate pileus, and more distant 

 gills. The latter species, moreover, is described as growing in moist or damp 

 places.
