Mycologia 
glabrous, hygrophanous, white, margin entire, concolorous ; lamel- 
lae sinuate, rather crowded, plane, pure-white ; spores globose, 
smooth, hyaline, granular, 7-8 /x, rarely reaching 10 /x; stipe white, 
hygrophanous, smooth, glabrous, hollow, ventricose or enlarged 
below, 6-10 cm. long, reaching 3 cm. thick. 
Type collected on the ground in woods near Seattle, Washing- 
ton, October 20-November i, 1911, W. A. Murrill 6jp. 
Melanoleuca subpessundata sp. nov. 
Pileus becoming plane or slightly depressed, usually with a 
conic or rounded umbo, gregarious, reaching 6.5 cm. broad ; sur- 
face dry or slightly viscid, subglabrous, latericious, bay on the 
umbo, usually smooth, varying at times to radiate-rimose and 
imbricate-squamulose except on the umbo; context with a farina- 
ceous odor and taste ; lamellae sinuate, usually with a decurrent 
tooth, ventricose, broad, not crowded, pale-rosy-isabelline, the 
edges often notched ; spores globose, smooth, hyaline, with gran- 
ular contents, 6-7 /x ; stipe slender, equal or enlarged below, 
smooth, pale-rosy-isabelline, glabrous above, decorated below with 
scattered, latericious fibrils, fleshy, solid or hollow, 7-9 cm. long, 
7-10 mm. thick. 
Type collected in soil in woods at Glen Brook, Oregon, Novem- 
ber 7, 1911, W. A. Murrill 755. Also collected in similar situa- 
tions at Mill City, Oregon, November 9, 1911, IV. A. Murrill 810; 
near Corvallis, Oregon, November 6-1 1, 1911, W. A. Murrill 
1002; and near Searsville*Lake, California, December ii, 1911, 
James McMurphy 122. This species suggests T. pessundatum in 
its coloring, but the stipe is much longer and the spores are wholly 
different. 
Melanoleuca subvelata sp. nov. 
Pileus convex-conic when young, not fully expanding, loosely 
clustered ; surface smooth, glabrous, moist but not viscid, lateri- 
cious, leaving a stain on paper, margin entire, strongly inflexed, 
concolorous or somewhat paler; lamellae sinuate-adnate to ad- 
nexed, not crowded, broad, ventricose, pallid; spores ovoid, 
smooth, hyaline, uninucleate, 5-7 X 2. 5-4.5 /x ; stipe subequal to 
slightly ventricose, rosy, smooth and glabrous at the apex, fibril- 
lose-shaggy near the center, fleshy, solid, 7 cm. long, about i cm. 
thick ; veil scanty, fibrillose, rosy, evanescent, persisting as fibrils 
on the margin and stipe.
