Fomes lucidus Leys. 



Pileus corky then woody, llabelliform, sulcate, rugose, laccate, 

 shining, at first yellow then reddish-chestnut. 



Stipe lateral, equal, concolorous; pores determinate, long. 

 minute, white then cinnamon. 



At the base of stumps, usually of Quercus, in low woods. 

 Pileus 3 to 8 cm. long, stem 2 to 5 cm. long, occasionally much 

 shorter or wholly obsolete with age. In young plants the pileus 

 is subzonate, the margin pale ochraceous, the disk ferruginous- 

 tinted and the laccate crust not manifest. The laccate coating 

 of the pileus and stem is at first brownish-ochraceous, becoming- 

 much darker as the plant matures. 



For a detailed study of this and allied species, with excellent 

 figures, see Atkinson, Bot. Gaz. 46: 321; our species being de- 

 scribed under the name Ganoderma pseudoboletum (Jacq.) Murrill. 



Fomes carneus Nees. 



Pileus effuscd-reflcxed, woody, hard, thin, rugose, smooth. 

 azonate, flesh-color without and within. 



Pores minute, round, decurrent at the base. 



Pileus longitudinally effused, imbricated, rarely solitary. 

 8 to 10 cm. long, 2.5 to 4 cm. wide, 5 to 7 mm. thick. 



Near the ground on decayed portion of a standing trunk, 

 woods, Glen Ellyn. September. Determined by Prof. Harper. 

 Often cited as a synonym of /•'. roseus Alb. & Schw. Professor 

 Peck considers the two species distinct, the latter being a thicker 

 ungulated plant with a crust. See Lloyd. Myc. Notes, No. 29. 



Fomes fraxineus Bull. 



Pileus corky-woody, glabrous, somewhat applanate, whitish. 

 then reddish and brown, at first even, then concentrically sulcate- 

 plicate, pallid within. 



Pores minute, short, reddish at first, as well as the margin 

 covered with a white sebaceous down. Odor strong ami pene- 

 trating. 



On stumps. River Forest, Harper: near the ground on a 

 standing trunk, Glen Ellyn. Moffatt. Unfortunately both 

 collectors failed to record the species of tree on which the speci- 

 mens were found. It is said to grow on Fraxinus americana.
