Cespitose, soft, white, stem thick, palmately branched, pileoli 

 laciniate, spreading, apex becoming fuscous. 



Hymenium definitely inferior, rugose. 



Grassy places in open woods. July and August. Stem 

 tough, flattened, branches subterete, fibrous-stuffed, white within ; 

 branchlets flattened, laciniate or only bifid at the apex. Spores 

 very variable, subglobose, broadly ellipsoid, ellipsoid-oblong or 

 subpyriform, granular, 6 to 10 x 3 to 6 /x. 

 Thelephora albido-brunnea Schw. 



Spongy-corky, widely effused; pilei at length narrowly reflexed, 

 becoming substipitate, subtomentose, brown. 



Hymenium nearly even, white. 



Glencoe. August. Harper. Growing about the bases of 

 dead shrubs. 

 Thelephora fimbriata Schw. 



Effused, soft becoming cartilaginous, incrusting, variable in 

 shape, producing long branches, decumbent, the primary terete, 

 the ultimate with fimbriate apices. 



Incrusting the stems of Fragaria. Riverside. Harper. 

 Identified by Prof. Burt, who states that some of our plants include 

 the form described by Prof. Peck as T. scoparia. 



STEREUM. 



Plants leathery or woody; pileate, central or lateral-stemmed, 

 effused-reflexed or entirely resupinate; free portion of the pileus 

 more or less strigose; hymenium smooth, arising from a compact 

 layer which is separated from the substratum by a floccose or 

 strigose layer of mycelium. Spores continuous, hyaline or oliva- 

 ceous.
