FAVOLUS. 141 



They grow to an immense size in the Valley. I have seen them to 

 measure from six to eight inches across. 

 Common on oak stumps. 



D. confragosa. Pk. Willow Daedalea. 



Pileus, corky, convex, coriaceous at first, then rigid, rough, 

 subzonate, reddish brown. 



Pores, sometimes round like a Polyporus, sometimes 



elongated into gill-like plates, like a Lenzites. 



The typical labyrinthiform is very seldom met with in our Valley. 

 This same species has been taken for a different species, the D. Crataegus. 

 Common on v^^illows. 



D. unicolor. Fr. One-color Daedalea. 



Pileus, coriaceous, villous- strigose, cinereous, and zones of 



the same color. 



Pores, labyrinthiform, at length torn and toothed. 



Common on dead branches of maple. It is called unicolor on account 

 of the similar color of the hymenium and the pileus. 



Gknus LI. FAVOI^US. Fr. 

 Hymenium alveolate, radiating, formed of the densely anas- 

 tomosing gills, elongated. Spores white. Dimidiate, some- 

 what stipitate. 



T. canadensis. Klotsch. 



Pileus, fleshy, tough, thin, reniform, fibrillose, scaly, and 

 tawny, becoming pale and glabrous. 



Pores, or alveoli angular, elongated, white at first, then 

 straw color. 



Stem, excentric, lateral, very short or none. 



Common on dead hickory branches throughout the Valley. Favolus 

 EuropecE and Favolus alveolarius, D.C., are considered the same, only 

 named in different periods of growth, young or mature specimens.
