74 Twenty-fourth Report on the State Museum, 



Lactakius seeifluus DC. 



Swamps in woods. Sandlake and Grreig. Our plant has a hol- 

 low stem and the color of burnt sienna — particulars in which it 

 disagrees with the description of L. seriflaus ; but the scanty 

 watery or serum-like milk is well shown by it. This is a large 

 but very fragile species, and much subject to the attack of insects. 

 When dry it has a decided but agreeable odor. 



Lactaeius Chelidonium n. sp. 



Pileus fleshy, firm, centrally depressed, smooth, slightly viscid, 

 of a grayish-green color with blue and yellow tints and a few nar- 

 row zones on the margin ; lamellse close, narrow^, forked and wavy 

 at the base, sometimes anastomosing, grayish yellow ; stem short, 

 subequal, smooth, hollow, colored like the pileus ; spores yellowish, 

 sfy\() ' in diameter. 



Plant 2' high, pileus 2' broad, stem 4:"-6" thick. Sandy soil 

 about pine trees. Saratoga. October. 



Taste mild, milk sparse, of a yellowish color resembling the juice 

 of Celandine or the liquid secreted from the mouth of grasshoppers. 

 The flesh when wounded is at first stained with a color like the 

 milk, then changes to blue and finally to green. Closely allied to 

 Z. deliciosiis, from which it difiers in its more narrow lamellae, 

 difi'erently colored milk, smaller spores, etc. 



Lactaeius fumostis 7^. sp. 



Pileus firm, convex, then expanded and slightly depressed in the 

 center, smooth, dry, smoky brown, or sordid white ; lamellae close, 

 adnate or slightly rounded behind, white, then yellowish ; stem firm, 

 short, smooth, stuffed, generally tapering downward ; spores dis- 

 tinctly echinulate, yellow, -j-^^ in diameter ; flesh and milk white ; 

 taste at first mild, then acrid. 



Plant 1.5'-2' high, pileus 1.5'-2.5' broad, stem 3"-5" thick. 

 Grassy ground in open woods. G-reenbush. July. 



The peculiar smoky hue of the pileus and yellow spores enable 

 this species to be easily recognized. The fiesh when wounded 

 slowly changes to a dull pinkish color. Related to L.fuliginosus.
