Agaricacese 



Lactarius. yellowish. Stem Yz\% in. long, 1-3 lines thick, equal, glabrous or 

 obsoletely pubescent, stuffed, rarely hollow, whitish or colored like the 

 pileus. Milk white, taste acrid and unpleasant, sometimes bitterish, 

 odor aromatic. Peck, 38th Rep. N. Y. State Bot. 



Smell agreeable, of melilot, as that of L. camphoratus. 



Spores spheroid, echinulate, 6-8/u. K.; subglobose, size variable, 

 6-io/u, Massee. 



The American plant, so far as observed, does not have the red hues 

 ascribed to the European.

This small Lactarius was found on several occasions. Its odor is 

 attractive, but its taste is not. Cooked it is of high flavor, but will 

 not be liked by many. 



L. aqui'flims Pk. watery. Pileus fragile, fleshy, convex or ex- 

 panded, at length centrally depressed, dry, smooth, or sometimes 

 appearing as if clothed with a minute appressed tomentum, reddish tan- 

 colored, the decurved margin often flexuous. Gills rather narrow, 

 close, whitish, becoming dull reddish yellow. Stem more or less 

 elongated, equal or slightly tapering upward, colored like the pileus, 

 smooth, hollow, the cavity irregular as if eroded. Spores subglobose, 

 rough, 7.6ft. Flesh colored like the pileus. Milk sparse, watery. 



Plant 3-8 in. high. Pileus 3-6 in. broad. Stem 5-10 lines thick. 



Swamps and wet mossy places in woods. Sandlake and North Elba. 

 August and September. 



The relationship of this plant is with L. serifluus, to which it was 

 formerly referred, but from which I am now satisfied it is distinct. The 

 hollow stem is a constant character in our plant, and affords a ready 

 mark of distinction. The plant, though large, is very fragile, and 

 breaks easily. The taste is mild or but slightly acrid. Sometimes there 

 is an obscure zonation on the pileus, which, in large specimens, is apt 

 to be irregular and much worm-eaten. The milk looks like little drops 

 of water when first issuing from a wound, but it becomes a little less 

 clear on exposure to the atmosphere. The decided but agreeable odor 

 of the dried specimens persists a long time. Peck, 28th Rep. 



This plant is sometimes cespitose. The pileus when dry is tawny- 

 gray and scaly or cracked scaly. The margin may be even or coarsely
