globose, 5-6 mic.), and has a peculiarity I have often noted in Fomes 

 igniarius, which was not overlooked in Boudier's plate, though never 

 mentioned, to my knowledge, in books. The old tubes have a white 

 deposit (lime, I presume), which shows plainly in a section of the 

 pileus of Fomes igniarius, but not any other species, to my knowledge. 

 If this is the true Fomes nigricans of Fries, and I presume it is, then 

 I should consider it a form of Fomes igniarius, but well worthy of a 

 name.

Second, there is a Fomes, in reality I think a form of Fomes 

 fomentarius, which was called Fomes nigricans, "Fries," by Bresadola 

 (Hym. Hung. Kmet, p. io 3 ), and is so known to some mycologists in 



3 Rev. Bresadola was mistaken in referring here Polyporus roburneus cfr. Myc. Notes, 

 p. 341 , but otherwise his reference is to this plant.
