74 TWENTY-FOURTH REPORT ON THE STATE MusErum. 
Lacrarius srErirLuvus DC. 
Swamps in woods. Sandlake and Greig. Our plant has a hol- 
low stem and the color of burnt sienna—particulars in which it 
disagrees with the description of Z. serifuus; 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. 
Lacrarius 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 ; lamellee close, narrow, forked and wavy 
at the base, sometimes anastomosing, grayish yellow; stem short, 
subequal, smooth, hollow, colored like the pileus; spores yellowish, 
spo 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 
L. deliciosus, from which it differs in its more narrow lamellee, 
differently colored milk, smailer spores, etc. 
LAcTARIUS FUMOSUS 7. SP. 
Pileus firm, convex, then expanded and slightly depressed in the 
center, smooth, dry, smoky brown, or sordid white; lamellze close, 
adnate or slightly rounded behind, white, then yellowish ; stem firm, 
short, smooth, stuffed, generally tapering downward ; spores dis- 
tinctly echinulate, yellow, ys4;y' in diameter ; flesh and milk white ; 
taste at first mild, then acrid. 
Plant 1.5’-2’ high, pilens 1.5’-2.5’ broad, stem 3’—5" thick. 
Grassy ground in open woods. Greenbush. July. 
The peculiar smoky hue of the pileus and yellow spores enable 
this species to be easily recognized. The flesh when wounded 
slowly changes to a dull pinkish color. Related to L. fuliginosus.
