Agaricacese 



Piuteus. Plant 1.5-3 m - high. PileuS 1-2 in. broad. Stem 1-2 lines thick. 



Decaying wood and prostrate trunks in woods. Hilly and mountain- 

 ous districts. June to September. 



The species is closely related to P. cervinus and P. umbrosus, but is 

 readily distinguished from them by the peculiar vesture of the pileus 

 and stem. The granules are so minute and so close that they form a 

 sort of plush on the pileus, more dense on the disk and radiating 

 wrinkles than elsewhere. The clothing of the stem is finer, and has a 

 velvety-pubescent appearance, but in some instances it breaks up into 

 small scales or squamules. The color of the pileus and stem is usually 

 some shade of yellow or brown, but occasionally a grayish hue pre- 

 dominates. The darker color of the granules imparts a dingy or smoky 

 tinge to the general color. The disk is often darker than the rest of 

 the pileus. Peck, 38th Rep. N. Y. State Bot. 



West Virginia mountains. Eagle's Mere and Springton Hills, Pa. 



Frequent. July to October, on decaying wood. Mcllvaine. 



P. granularis is a much smaller species than P. cervinus and its allies. 

 At Eagle's Mere, Pa., August, 1898, it was quite plentiful in mixed 

 woods. Its caps are excellent. 



*** Pileus naked. 



P. admira'bilis Pk. admirable. Pileus thin, convex or expanded, 

 generally broadly umbonate, glabrous, rugose-reticulated, moist or hy- 

 grophanous, striatulate on the margin when moist, often obscurely striate 

 when dry, yellow or brown. Lamellae close, broad, rounded behind, 

 ventricose, whitish or yellowish, then flesh-colored. Stem slender, 

 glabrous, hollow, equal or slightly thickened at the base, yellow or yel- 

 lowish white, with a white mycelium. Spores subglobose or broadly 

 elliptical, 6.5-8x6.5^. 



Var. fus'cus. PileilS brown or yellowish-brown. 



Plant 1-2 in. high. Pileus 6-10 lines broad. Stem .5-1 line thick. 



Decaying wood and prostrate trunks in forests. Common in hilly and 

 mountainous districts. July to September. 



This beautiful Piuteus is closely related to P. chrysophlebius B. and 

 R., a southern species, which, according to the description, has the 

 veins of the pileus darker colored than the rest of the surface and the
