90 Murrill: Polyporaceae of North America 



ever, the plant in the Schweinitz herbarium is undoubtedly Daeda- 

 lea ambigua and not P. hemileucus, which settles the question of 

 type. 



Trametes ineaua Berk, was founded on specimens collected by 

 Lea on dead trunks of trees in Ohio. These specimens were pos- 

 sessed of a very short lateral, disciform stem, a yellowish hymen- 

 ium and roundish, or rarely linear and sinuous, pores. The name 

 was changed to Trametes Berkeley! in 1891 by Cooke because of 

 Polyporus (Trametes) incana Lev. (Bonite, Crypt. 183. 1844-1846), 

 described from the Philippines. Although Trametes seems to be 

 used here as a subgenus, the author writes it as a genus lower 

 down on the same page when he comes to refer to and describe 

 the figures : " PL 13J. f. 2. Trametes incana de grandeur natu- 

 relle," etc. 



Daeeialea ambigua was described by Berkeley in almost the 

 same breath with the previous species and the specimens were 

 collected in the same locality by Lea. Montagne considered the 

 two species the same, but Berkeley, influenced to a considerable 

 extent by Lea, finally decided to make them distinct because of 

 the narrow, sinuous pores of the latter. 



Trametes lactea was described from plants sent to Fries from 

 Carolina by Curtis. These plants were evidently porous forms of 

 this species and naturally fell under the genus Trametes so far as 

 Fries could determine from the material. 



Lenzites glaberrima was also described from Carolina material 

 sent by Curtis. This time the tubes were lenzitoid and anasto- 

 mosing and there was an orbicular disc for the base. 



Daedalea glaberrima was meant by Berkeley for an entirely 

 distinct species. The pores are described as " at length sinuous" 

 and the stem as "lateral, one-half an inch long and wide." The 

 type specimens were sent from South Carolina by Curtis. 



In addition to the above, several other names have been used 

 quite freely by collectors and systematists in connection with this 

 species. Trametes marchioiuca, for example, described from the 

 Marquesas Islands by Montagne (Voy. Pole Sud, 204. 1845), is 

 often treated as a synonym of D. ambigua. Trametes Mulleri 

 Berk, is applied to Cuban forms of D. ambigua at Kew and else- 

 where, although the type locality of the species is the Victoria
