14 JOUKXAL OF THE MiTCHELL SoCIETY [Jwie 



infundibuliform with the margin uplifted, still inrolled, outline 

 rather regular, or lobed and unevenly developed on one side; surface 

 quite glabrous except on the margin, which is typically covered with a 

 soft, tomentose, cottony roll, appearance of white kid at first, with buff 

 or brownish-ochraceous or cinnamon stains, then more or less cracking 

 or roughish and more chalky looking. Flesh about 7 mm. thick at 

 stem, pure white, elastic, not brittle, rather slowly but decidedly 

 acrid, and with an unpleasant taste, thinning quickly on the inrolled 

 portion; smell like sour bread, strong after maturity. Milk white, 

 unchanging, acrid, sparce. 



Gills rather crowded, in age less so, appearing slightly decurrent, 

 3.5-4.5 mm. wide in center, narrow at each end, white at first, then 

 pallid cream, with an olive tint as they begin to dry, turning ochra- 

 ceous or dull brown when bruised, some forked. Margin regular and 

 even, remarkable for the fine fibers which often stretch across from 

 gill to gill and are made visible by the spores that stick to them. 

 They may be seen both in half-grown and mature plants. 



Stem about 2-3 cm. long and 1,5-2,5 cm, thick at top, tapering 

 downward and firmly attached at the blount base by fine mycelium ; 

 surface beautifully and densely soft white tomentose all over, quite 

 firm and solid all through, the fiesli like that of the cap, but at times 

 with ochraceous stains. 



Spores (of ISTo, 1877) white, regularly elliptic, distinctly tubercu- 

 late, 7.4-8 x 10,6-11, 2^, 



The plants grow among leaves and are often covered by them. The 

 white mycelium is conspicuous running from the base of the stem. 



This species is much like L. velereus, but the cap is not tomentose 

 as in that species except for the marginal roll, the spores are strongly 

 warted, and dried plants are much lighter. It is also shaped like 

 L. piperatus, but is easily disting-uished from that species by the 

 tomentose stem and much deeper and less crowded gills. For an 

 illustration in color see I^. Y. St, Mu, Eep. 54 : PI, 70. 1902.
