subcinereus, British America, Berkeley = Polyporus adustus as acknowledged by 

 Berkeley. Specimens so labled are found in Fries' herbarium and at Paris. 



suberis, Africa, Patouillard. Unknown to me. 



suberosus, Europe, Linnaeus. An old supposed synonym for Polyporus be- 

 tulinus sometimes used as a juggle. 



subgilvus, South America, Spegazzini = Polyporus gilvus sans "sub". Specimen 

 at Paris. 



sublilacinus, Southern United States, Ellis. Based on a single specimen from 

 Langlois. It is same as the common Polyporus gilvus with slightly different tex- 

 tures, tending towards Polyporus licnoides. It is a question if Polyporus licnoides 

 is other than a form of Polyporus gilvus and surely there is no room" for a "species" 

 between them that is based on a single specimen and "known only from the type 

 locality." 



subluteus, Canada, Ellis. I have some cotype material of this but it has never 

 come out very distinctly as a species for me. 



subpictilis, New Guinea, Hennings. Referred by Bresadola to Polyporus 

 bicolor. The type at Berlin is quite thin to be bicolor, nor is it spotted red as bicolor 

 typically is, still it has same color context and may be a thin form. I can not say 

 to the contrary. 



subpruinatus, Java, Bresadola = Polyporus anebus, for me. 



subrubidus, Philippines, Murrill = Polyporus bicolor. 



subsericellus, Europe, Karsten. Unknown. 



subsimulans, Cuba, Murrill. This was merely a name change of simulans 

 which Cooke alleged to come from Cuba, but probably came from Ceylon. Simulans 

 being a duplicate was changed by Murrill to subsimulans where he included this 

 Ceylonese (?) plant in his "North American" Flora. Had he called it Polyporus 

 fumosus it would not have been far from the truth. 



subtropicalis, South America, Spegazzini = Polyporus licnoides, typical in 

 everything excepting a little thicker. 



sulphuratus, Mexico, Fries = Polyporus rheicolor of this pamphlet, =also 

 Polyporus Splitgerberi and at Upsala where the two species can be compared they 

 are same thing. Why Fries renamed it I do not know as he had Montagne's specimen 

 to compare. The flesh is orange yellow rather than sulphur yellow. 



sulphureo-pulverulentus, Siberia, Karsten. Nothing is known about it (for- 

 tunately). 



surinamensis, South America, Miquel. No type known to me though at Paris 

 are specimens from Surinam so determined by Leveille, and may be cotypes. They 

 are the unzoned form of Polyporus zonalis called also by Leveille Polyporus rigidus. 



Symphyton, United States, Schweinitz. No specimen preserved. The de- 

 scription indicates that it was Polystictus biformis, a common American species, 

 not otherwise accounted for in Schweinitz' record. 



tamaricis, Europe, Patouillard = Polyporus rheades growing on tamarix. This 

 tamarix form has only recently been recognized by me as being same as Polyporus 

 rheades. Bresadola figured it as Polyporus rheades, afterwards Patouillard thought 

 it was different and named it Polyporus tamaricis. Bresadola accepts this correc- 

 tion and I have always thought it was correct until I began to compare the different 

 species with colored spores to find out the exact difference between them. Then 

 I could not find any as to Polyporus tamaricis and Polyporus rheades at least, 

 and I do not think there is any excepting the host. 



terebrans, Cuba, Berkeley. Based on a single specimen same context and 

 color as Polyporus fumosus and I would prefer to so refer it with doubt than to 

 try to maintain a species on it. 



testaceus, Europe, Fries. Pileus suberose, sordid testaceus, zonate within. 

 Pores minute, white. On Poplar. Unknown to me. Evidently close to alutaceus 

 and I suspect the frondose wood form of same thing. 



Testudo, Australia, Berkeley = Polyporus durus. The type at the British Museum. 



texanus, Texas, Murrill. Based on young specimen of Polyporus corruscans 

 growing on mesquite. I have seen three collections, the type, and also from Long 

 and Yon Schrenk all on mesquite. 



Thelephoroides, South America, Hooker = Polyporus conchoides, and an 

 earlier name for it, when those sacred principles of priority get into good working 

 order. No one has yet juggled it however.
