is well marked by the peculiar elevated zones or lines of the pileus. 
The plant is closely gregarious, and sometimes the pilei are confluent. 
The relationship is with H. connatum and H. zonatum. 
, Irpex nodulosus, ». sp. 
Resupinate, forming suborbicular patches four to ten inches or 
more in diameter, subseparable; the subiculum thick, tough; the 
hymenium dentate-porous toward the thick definite margin, centrally 
nodulose and prolonged into unequal compressed truncate or laciniate,

Corticium olivaceum, Fr. 
Decayed wood. North Greenbush and Slingerlands. 
Clavaria albida, xn. sp. 
Plants 2 to 4 in. high, whitish ; stem short, thick, generally taper- 
ing downwards, divided above into a few short, thick, much-branched 
ramuli, ultimate branches densely crowded, terminating in a few 
short, blunt teeth; flesh firm, dry, whitish, taste tardily acrid, then 
bitter; spores oblong, pale ochraceous, .0005 to .0006 in. lowg, .0002 
broad. 
Ground in thin woods. Menands. August. 
The species has the structure of C. botrytis and C. flava, but itis readily 
distinguished from these by its uniform whitish color, the tips of the 
branches being concolorous. 
Clavaria densa, n. sp. 
Tufts 2 to 4in. high, nearly as broad, whitish or creamy-yellow, 
branching from the base ; branches very numerous, nearly parallel, 
crowded, terete, somewhat rugose when dry, the tips dentate, con- 
colorous ; spores slightly colored, subelliptical, .0003 to .0004 in. long, 
-0002 to .00034 broad. 
Ground in woods. Selkirk. August. 
Apparently closely allied to C. condensata, but differing decidedly 
in color.
