confusus. Polyporus confusus Mass. Kew Bull. 1910: 250. 



1910. Described from Louisiana. See " Southern Polypores," 



p. 22. Closely related to Polyporus cyathiformis Lev. 

 conglomerus. Polystictus conglomerus C. G. Lloyd, Myc. Notes 



50: 706. /. 1056. 191 7. Type not seen, but doubtless belongs 



in Coriolus. 



" Pileus thin, rigid, developed from a hard, white, conglomerate, myceloid 

 base. Surface unicolorous, between isabelline and honey yellow, velvety with 

 soft hairs, faintly zoned. Pores minute, rigid, alutaceous. Spores 3X5- 

 hyaline. 



" The feature of this plant is the method of development from a con- 

 glomerate base, unknown to me in any other species. The rigid pileus and 

 pores point to Trametes, but it is customary to refer such thin plants to 

 Polystictus. In grouping it we would put the species in the same section as 

 versicolor. The specimens were sent to Mr. Plitt by Dr. H. E. Hone from 

 California." 



cutifractus. See Tyromyces cutifractus Murrill in Western 

 Polypores, p. 7. 



cylindrispora. Poria (or Fomes) cylindrispora C. G. Lloyd, 

 Letter 65 : 9. March, 1 91 7. Fomitiporia cylindrispora ( Lloyd ) 

 Murrill. Type not seen. Described from Weir's collection in 

 Montana. 



" Perennial, resupinate, inch thick. Context ferruginous (about snuff 



brown Ridgway). Pores minute, with silvery glancing mouths. Pore layer 

 narrow, 2-3 mm. wide. Setae abundant, slender, not inflated at base. Spores 

 hyaline, cylindrical, 2^2-3 X 6-7, smooth. 



" Mr. Weir finds this abundant on Quercus Garryana. To the eye it is same 

 as the common Poria punctata (Poria obliqua of American traditions, not 

 Europe), but no other known similar species has cylindrical spores." 



epileucus. Not American, so far as I know. 

 Farlowii. Polyporus Farlowii C. G. Lloyd, Syn. Apus Pol. 363. 

 /. 697. 191 5. Type not seen. Apparently belongs in Inonotus. 



" Pileus applanate, wavy. Surface strongly hispid, with suberect, brown 

 hairs. Context hard, ferruginous, brown (antique brown), fibrillose. Pores 

 small, round, firm, concolorous. Setae abundant, straight, projecting 30 fi. 

 Spores colored, ellipitical, 2^ X 4 T A~B- 



" The type at Kew was collected in Arizona and, according to the label, 

 sent by Farlow to Cooke, who determined it as Polyporus endocrocinus. The 

 yellow coloring matter is not soluble in water, but readily so in a potash solu- 

 tion. This must be an unusual species in our Western States. It has never 

 reached us, nor is it found at New York."
