TBE POLYPORACEAE OP WISCONSIN. SJ 



tund or lengthened radially ; tubes of unequal length with the trama 

 of the same substance as the pileus. The dissepiments are seldom 

 toothed or torn. 



§1. Context wJiite or whitish. 



Trametes sepium Berkeley. 



Pilei effused, at base reflexed, often laterally confluent, finely tom- 

 entose, successively zonate, pale wood color, leathery, sometimes when 

 young three cornered, substance white; pores slightly sinuous, about 

 5/6 mm. in diameter. 



Found in North and South Carolina on oak, pine, and cypress; in 

 Alabama on laurel and sassafras ; in Connecticut, Ohio and New Jersey 

 on oak. (26, VI, p. 342.) 



This small, large pored Trametes is quite common on oak fence 

 posts, fence rails and on oak trunks. It has been found at Elkhom, 

 Horieon, Madison, Bangor, Sparta, Crandon and Oakfield. The larg- 

 est specimen was 3 cm. broad, 1 cm. long ; flesh of the pileus 2 — 4 mm. 

 thick, tubes from 4 — 8 mm. in length. 



The pilei are wliite, pulvinate, leathery, more or less imbricated, con- 

 fluent, margin acute, inflexed and finely tomentose when young. The 

 pores are large, angular or sinuate, sometimes decurrent upon the 

 soft white tomentose mycelium below. In some specimens the pores 

 are nearly alveolar or hexagonal, reminding one of Favolus. The 

 color of the pores varies from white, to straw-yellow and yellowish 

 brown. Sometimes the pores become torn into lamellae and teeth. 



The zones are not very apparent on young specimens but are more 

 so on mature ones, on which also slight concentric sulcations some- 

 times appear. The tomentose pubescence disappears with age and 

 weathering. 



This species is closely related to Trametes serialis Fries, and Tram- 

 etes serpens Fries. It is, however, less resupinate and has larger pores 

 than either of these species.

Trametes serialis Fries (Plate III, fig. 13). 



Pilei laterally confluent, effuso-reflexed, corky-coriaceous, yellowish 

 to straw color, with obtuse margin. Pores small, white, unequal, in 

 the reflexed part roundish, in the effused part irregular, oblique, 

 toothed.
