Sarcodon fumosus sp. nov. 
Hymenophore terrestrial, inesopodous, small, 3-5 cm. high, 
ash-gray to smoky ; pileus plane to convex, 2-3 cm. wide, 2-3 
mm. thick ; surface even, subpubescent, ash-gray to smoky-oliva- 
ceous-brown when dried ; margin thin, fertile, minutely serrate ; 
substance fleshy-spongy when fresh, somewhat tough, flexible, 
compact, subwaxy toward surface, soft fibrous within, olivaceous, 
when dried ; stem slender, subcentral, inclined or curved, atten- 
uate upward, subpubescent at base to glabrous shining toward the 
cap, 2-4 cm. long, 3-10 mm. wide ; teeth short, slender, terete, 
tapering, acute, uneven, not decurrent, pale t 5 dirty-white, some- 
what crowded, 2-5 mm. long or less, 0.2-0.4 mm. wide, 9-12 to 
a square mm. ; spores dark, coarsely and densely tuberculate, 
ovoid, 7-9 ju, X 9-1 1 ft- wide ; basidia clavate to oblong, narrowing 
abruptly at the base, 7-10 /j, wide by 25-30 long ; sterigmata deli- 
cate, conical, incurved, 3-4 ju. long; hyphae of trama colored, dis- 
solving out freely in KOH, becoming hyaline, slender, smooth, 
thin-walled, collapsing when dried, recovering slightly in KOH, 
forming an intricate tangle but slightly separable in KOH, septate 
without clamp-connections, segments extremely long, somewhat 
irregular, more or less constricted at the septa, 4-6/1 wide; hyphae 
of the teeth very slender, parallel, 3-4/1 wide; taste bitterish. 
The type of the species is Murrill and House Jp4, North Caro- 
lina, deposited at the New York Botanical Garden. 
Sarcodon roseolus sp. nov. 
Hymenophore terrestrial, inesopodous, gregarious, small to 
medium size, 4-6 cm. high, pale-rose-color; pileus plane to con- 
vex, 3-4 cm. wide, 0.5 cm. or less thick) surface pubescent and 
slightly imbricate, scaly, even, whitish tinged with old-rose ; mar- 
gin thin, incurved when dried ; substance fleshy-tough, drying into 
two layers, an inner waxy or gummy, subtranslucent layer, and 
an outer dry, opaque, subfibrous layer; stem slender, subcentral, 
strongly inclined, subeven, slightly radicating, scabrous, 2-3 cm. 
long by 7-10 mm. wide ; teeth very short, terete, tapering, acute, 
uniform, decurrent and abortive on the stem, not crowded, 0.3-0.7 
mm. long by 0.1-0.2 mm. wide, 16-20 to a square mm.; spores 
pale-brown, tuberculate, ovoid, 4-5 X 5-6 /a wide; basidia clavate, 
four-spored, 5-6 /a wide; sterigmata slender, capillary, 3 /a long; 
hyphae of inner portion of pileus clouded, smooth, slender, thin- 
walled, collapsing when dried, recovering in water and KOH, 
forming a somewhat intricate and compact tangle, scarcely sepa-
