tiliophila, United States, Murrill. Based on a thick specimen of Polyporus 

 alutaceus. 



tomentoso-quercinus, United States, Johnson. Amateur work of which no 

 type exists but from the description no doubt that Murrill has correctly referred 

 it to Polyporus obtusus. 



Torreyi, United States, Gerard as var. of Polyporus volvatus. Based on 

 specimens abnormally stiped. 



trachodes, Java, Leveille = Polyporus scruposus which is a form of Polyporus 

 gilvus. 



trichocoma, Tahiti, Fries. No type exists. 



tristis, Europe, Persoon. No type in Persoon's herbarium. Fries thought it 

 might be abietinus, but description seems to me to point to the large pored form 

 of Polyporus adustus, viz., Polyporus crispus. 



tristis, Europe, Roumeguere as Trametes (sic) is the common Polyporus adustus 



tristis, Java, Leveille. No type found by me = Polyporus vinosus it is stated 



tumidus, Africa, Bresadola. Unknown to me. It belongs to section 103 

 which has now more named species than it is practical to maintain. They are all 

 very much alike. 



tyrolensis, Europe, Saccardo. Change of Polyporus Schulzeri which is prob- 

 ably obtusus. 



ufensis, Siberia, Karsten. Unknown to me and from description can not refer 

 it to a section even. 



undulatus, United States, Schweinitz. No specimen known. 



ungulatus, Australia, Berkeley. Pileus sessile ungulate, broadly attached. 

 Surface hard, smooth, dull, no distinct crust. Slightly adustus. Flesh white, 

 hard. Pores medium, adustus (now). Spore? globose, 4-5 mic. Known only 

 from the type at Kew. A single collection. The pores of the specimen grew in 

 irregular areas of growth, starting at different levels and growing different lengths,, 

 but I do not know but that is accidental in this specimen. The general nature 

 and color of the pores are that of Polyporus fumosus and I have a feeling that it is. 

 an aberrant form. 



unguliformis, Philippines, Murrill = Polyporus immaculatus, Murrill's name 

 is the fifth that the plant has had. 



unicolor, United States, Schweinitz. The specimen in Schweinitz' herbarium 

 is Polyporus obtusus, as has long been known, but the specimen does not agree 

 with the description and it is far more probable that Schweinitz knew Polyporus 

 obtusus as Sistotrema spongiosum changed by Fries to Polyporus labyrinthicus. 



venetus, Europe, Saccardo. Unknown. Something growing in a cave and 

 no doubt an abnormality. 



verecundus, Cooke, Berkeley = Polyporus immaculatus of same author, that is, 

 as to the probable type. All specimens are in Cooke's writing, hence this "type" 

 is of doubtful authority. 



vermiculus, Europe, Veulliot. Seems from description to be Polyporus mollis. 



virginii-Cuboni, Brazil, McGinty. Change of armeniacus because the name 

 was preoccupied. However, as the original turns out to be the common Polyporus 

 amorphus, the occupation was only temporary, and the change was unnecessary. 



vulneratus, Java, Leveille = Polyporus bicolor. 



vulpinus, Europe, Fries = The poplar form of Polyporus rheades. For full ac- 

 count and history, see page 362. 



Weberianus, Samoa, Bresadola = Polyporus fruticum. 



Weinmanni, Europe, Fries = Polyporus mollis. There is a cotype at Kew.
