 i. p. 235. Dimidiate, thick-lobed, spongy, between fleshy and 

 fibrous, hirsute, zoned within, margin thin ; prickles rather short, awl- 

 shaped. No. 1648. Santee River. Ravenel. 



* Hydnum (Apus) septentrionale. Fr. — No. 5203. Alabama, 

 Peters. On Linden.

•- 17G. Hydnum (Apus) glabrescens. B. 4' Bar. — Umbrinum, 

 pileo dimidiato, glabrato, concentrice sulcato ; aculeis 'elongatisj 

 acutis, demum compressis. No. 1634. Car. Inf. Ravenel, on 

 Carya. Ceylon, G. H. K. Thwaites. No. 385. Central Pro- 

 vinces. Pale umber, or reddish-brown, with a paler margin ; pileus 

 1-3 inches across, dimidiate, more or less imbricated, and sometimes

 concentrically ; prickles of the same colour as the pileus, acute, 

 more or less compressed, about a line long. 



•* * Hydnum (Apus) flabelliforme. B. — After examining a large

 Schweis. Indeed, it approaches so near to unusually thick speci- 

 mens of II. ochraceum, that it is sometimes difficult to distinguish.

 minuto, candido, villoso, aculeis acutis tomentosis. No. 4936. Car.
