Murrill: Polyporaceae oe North America 93 



Pers., but the author, who was at that time but little acquainted 

 with oriental forms, thinks that the stipe and pores sufficiently 

 distinguish it from Persoon's species. 



This exceedingly variable and very attractive species is abun- 

 dant on decaying wood in tropical America. In some localities 

 the young sporophores, although tough, are used as food by the 

 natives. It differs from A. Aesculi in being thin and flexible and 

 usually much more zonate, though at times the two species are 

 not easily distinguished. One is here forcibly reminded of Pycno- 

 porus cinnabarinus and Pycnoporus sanguineus, which exhibit much 

 the same relations, indicating that the effect of tropical conditions 

 may be to produce a thinner, more expanded and more zonate 

 sporophore.

Species inquirendae 



Daedalca subtomentosa Schw. Syn. Fung. Car. 68. 18 18. De- 

 scribed from North Carolina material as follows : 



" D. minor gibbosa, zonis elevatis subtomentosis albida, sinu- 

 bus poriformibus angustis aibis et pallidis. Passim. Species non 

 valde distincta. Pileus glaber tuberculosus." 



This is very probably another synonym of A. confragosus, but 

 I have not been able to find type material. Even Schweinitz him- 

 self says that it is not a very distinct species. 



Irpex maximus Mont. Ann. Sci. Nat. II. Bot. 8: 364. 1837. 

 Syll. Crypt. 174. 1856. Polyporus labyrinthicus Mont. Cuba, 

 406. 1842 (not P. labyrinthicus Fr. Elench. 83. 1828). 



This species was described from material collected by Ramon 

 de la Sagra on the trunks of trees in Cuba. Montagne's earlier 

 description is as follows : 



" Pileo coriaceo tenui reniformi plano-convexo velutino mar- 

 ginem versus repandum acutum concentrice sulcato demum basi 

 glabrescenti subradiato dentibusque confertis acutis pubescentibus 

 ochroleucis."
