quite close, perhaps the same as Stereum decolorans, but I judge it differs in its 

 habits of growth (not caespitose). 



STEREUM FISSUM (bis) (Hennings as Thelephora). Known only from 

 the type Brazil. It is same as Stereum decolorans in all characters excepting it is 

 cut into segments. In my opinion, only a form of Stereum decolorans. It prob- 

 ably, however, did not grow caespitose as does evidently the type of Stereum de- 

 colorans. 



STEREUM GLABRESCENS (Fig. 558). Pileus reddish-bay 

 brown, spathulate, tapering to a distinct stipe, smooth, sometimes 

 faintly zonate. 



This species is known from a few collections, Brazil. The color 

 is much like Polystictus xanthopus. It is quite firm and a typical 

 Stereum as to texture.

Stereum glabrum. 





STEREUM MOELLERL Spathulate or petaloid, tapering to 

 a stem-like base. Surface smooth, minutely silky, even, dark, blackish, 

 faintly zoned. Hymenium even, pale, almost white or slightly cin- 

 ereous when old, contrasting with the dark upper surface. Cystidia, 

 none. 



This is known only from Brazil. Types are at Berlin, also co- 

 type in British Museum. 



STEREUM FISSUM (Fig. 559). Pileus cuneiform or spathu- 

 late. Sometimes entire, but generally cut into cuneate segments, 

 tapering to a short base, smooth, reddish brown. The hyphae are 

 pale color. The plant was said to be "white when fresh, turning 

 yellowish." It is known from the types at Kew, from Brazil, which
