is well marked by the peculiar elevated zones or lines of the pileus. 

 The plant is closely gregarious, and sonietimes the pilei are conliuent. 

 The relationship is with H. connatum and H. zonatum. 



Irpex nodulosus, n. sjx 



Resupinate, forming suborbicular patches four to ten inches or 

 more in diameter, subsej^arable ; the subiculum thick, tough; the 

 hymenium dentate-porous toward the thick definite margin, centrally 

 nodulose and prolonged into unequal compressed truncate or laciniate, 

 rarely terete acute aculei, whitish, centrally yellowish or pale 

 ferruginous.

Radulum pendulum, Fr. 



Dead j)rostrate trunk of basswood, Tilia Americana. Argusville.

This is distinct from our other species by its reflexed pileate form. 

 The pileus is whitish and pubescent, or at length nearly smooth. The 

 species is quite rare. 



Corticium olivaceum, Fr. 



Decayed wood. North Greeubush and Slingerlands. 



Clavaria albida, n. 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; s^Jores oblong, pale ochraceous, .0005 to .0006 in. long, .0002 

 broad. 



Ground in thin woods. Menands. August. 



The species has the structure of C. boty-ytis and G.Jlava, but it is readily 

 distinguished from these by its uniform whitish color, the tips of the 

 branches being concolorous. 



Clavaria densa, n. sp. 



Tufts 2 to 4 in. 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. 



Aj)parently closely allied to G. condensata, but differing decidedly 

 in color.
