Other Yellow Species 



Poria calcea Fries, var. sulphured. Romell so determined 

 specimens collected by me on a white pine log in Maine, August 

 28, 1905, which were distinctly lemon-yellow when fresh. I. 

 have not studied this species very carefully, as the specimens are 

 apt to be sterile. 



Porta cremeicolor Murrill. Very pale yellow. See Mycologia 

 12 : 85. 1920. 



Poria fatiscens (Berk. & Rav.) Cooke. Sulphur-yellow to 

 chrome-yellow, at least in herbarium specimens. See Mycologia 

 11 : 238. 1919. 



Poria heteromorpha Murrill. Distinctly ochraceous, becoming 

 fulvous with age. See Mycologia 12 : 92. 1920. 



Poria incerta (Pers.) Murrill. The herbarium specimens of 

 this common, variable species are often pale-yellowish. See 

 Mycologia 12 : 78. 1920. 



Poria medullapanis (Jacq.) Pers. Often a beautiful egg-yel- 

 low or chrome-yellow, especially on the margin of young plants ; 

 hence the names P. pulchellus and P. holoxantha assigned to 

 American material. See Mycologia 12 : 48. 1920. 



Poria myceliosa Peck. Tubes pale-yellow. See Mycologia 12: 

 301. 1920.

 Mycologia 11 : 242. 1919.

 gantly luteous, tubes pallid. See Mycologia 11 : 234. 1919.
