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

 The plant is closely gregarious, and sometimes the pileiareconlluent. 

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

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

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

 si:>ecies is quite rare. 



Corticium olivaceum, Fr. 



Decayed wood. North Greenbush and Slingerlands. 



Clavaria albida, a. .s-jy. 



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 .000(5 in. long, .0002 

 broad. 



Ground in thin woods. Menands. August. 



The species has the structure of G. botryti>i and C.Jlam, 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 puriillul, 

 crowded, terete, somewhat rugose wjicn dry, the tips doutato. con- 

 colorous ; spores slightly colored, subelliptical, .0003 to .0004 in. long. 

 .0002 to .00034 broad. 



Ground in woods. Selkirk. August. 



Apparently closely allied to 0. condenxata, but dilToring decidedly 

 in color.
