the synonyms. Thus H. pudorinum Fr. might be regarded as a 

 form intermediate between H. ochraceum Pers. and H. dichroiim 

 Pers., while H. Rhois Schw. strictly interpreted is perhaps inter- 

 mediate between H. dichroum Pers. and H. flabelliforme Berk.

No type of H. rawakense Pers. was found in Persoon's her- 

 barium at Leyden, but in the Herbarium of Paris there was found 

 a specimen with the following label apparently in Persoon's hand ; 

 " 37 hydnum rawakense Rawak. C. Sandrenaud," and then there 

 was added in a different hand " spec. Persoonianum." The 

 specimen would appear to be in all probability the type of the 

 species. It is discolored as though it had some time been poisoned, 

 and has evidently been formerly glued to a sheet teeth down, the 

 teeth being gummed up with the glue.^ In spite of these deformi- 

 ties, there appears to be but one group of forms to which it 

 could belong, a species that ranges from the West Indies through 

 South America .and the islands of the Southern Pacific. The 

 most distinctive features of the species are the thin, submembran- 

 ous, spreading pilei, the pubescent, ochraceous surface with a 

 somewhat clearly marked central or basal disk and a broad 

 marginal portion marked with more or less distinct light and 

 dark zones. At Berlin specimens of this species were noted 

 from Brazil and from New Guinea, the latter having the margin 

 distinctly lobed. 



The type oi H. reniforme B. & C. is in the Berkeley herbarium 

 at Kew and is marked "301 Hydnum reniforme Bk. Cuba, 

 Wright, (Curtis)." It appears to be unquestionably the same 

 thing as H. razuakense Pers. The specimen at Kew, " Ravenel 

 No. 1634," the type of H. glahrescens, appears to me to be prob- 



^ In Persoon's herbarium several specimens were observed mounted in this 

 unusual manner. See S. ochraceum.
