STEREUM NITIDULUM (Fig. 542). Pileus smooth, zonate, 

 reddish-bay, infundibuliform, with mesopodial stipe, and rooting base. 

 The type specimen (from Brazil) grew in the sand which forms a ball 

 at base of stem. One of the specimens has a long rooting base. 



Berkeley referred to nitidulum from Ceylon, specimens that I 

 think have no resemblance to it and which I would refer to elegans. 

 Stereum nitidulum occurs both in American tropics and the East. 

 As found in the museums, it is generally furnished with a rooting 

 base. Sometimes it is quite small. Recent collections by Rick are 

 referred to Stereum elegans.

The following two species are quite close to nitidulum. Same shape, surface, color, etc., but they 

 differ in habits and size. 



STEREUM RAVENELII (Fig. 543). This is quite close to Stereum nitid- 

 ulum, but more slender and delicate and with a more slender stem. It grows in
