5. Hapalopilus fulvitinctus (B. & C.) 

 Polyporus fulvitinctus B. & C. Jour. Linn. Soc. Bot. 10: 313. 



1868. 



This species was collected on dead wood in Cuba by Wright. 

 It differs from H. gilvus chiefly in having smaller and more 

 rounded spores and paler substance ; while in surface characters 

 and consistency the two species are much alike. I know of no 

 collections of the plant except those at Kew, and our knowledge 

 of its habits and distribution is most meagre. 



6. Hapalopilus hispidulus (B. & C.) 

 Polyporus hispidulus B. & C. Jour. Linn. Soc. Bot. 10 : 319. 1868. 

 Collected on decayed wood in Cuba by Wright. Known only 

 from the rather scanty type collections at Kew. Pileus reddish - 

 brown, finely hispid except near the margin, context brown, hy- 

 menium brownish-gray, spores ovoid, smooth, hyaline, 3 x Z-$ <'-, 

 immature, hyphae very pale ferruginous. 



Species ixquirendae 



Polyporus crocatus Fr. Epicr. 477. 1 836-1 838. Described 

 from Leibman's Mexican collections. Transferred to Polystictus 

 in Novae Symbolae, 91. 1 851. Probably a form of P. licnoides 

 Mont. I hesitate to reduce P. licnoides to synonymy, however, 

 without further investigation. 



Polyporus sordidus Berk, in Fries, Nov. Symb. 80. 185 1. 

 Name changed to Polyporus sordidulus in Cooke's enumeration of 

 polypores owing to the discovery of another species bearing the 



former name. 



Polyporus endozonus Fr. Nov. Symb. 54. 185 1. Collected by 

 Oersted on trunks in the Island of San Juan. I have not seen the 

 type of this species. It is said to be very thick and narrow, with 

 smooth, rigid pileus, roughly fibrous context and very small short 

 pores, which become dark umber with age. Fries treats it next to 

 P. scruposus and it is certainly not far from H. gilvus, but the 

 pileus is too thick and the substance too fibrous for this species.
