THE POLYPORACEAE OF WISCONSIN. 73 



orally becomes more or less blackened after the first year. Occasion- 

 ally a new flesh-colored growth overspreads it either wholly or in part. 

 Two forms occur which depart somewhat from the type. In one the 

 pileus is more or less zonate, especially toward the margin, though of- 

 ten indistinctly so. Sometimes the margin is zonate and the rest tu- 

 berculate. This seems to me to be worthy of varietal distinction, and 

 I propose for it the name Fomes carneus subzonatus n. var. Its pilei 

 are often imbricated, and the color is paler than in the common form. 

 In the other the surface of the pileus is uneven and scabrous with mi- 

 nute tufts of short, erect hairs or fibrils. To the naked eye the surface 

 appears somewhat granular. To this variety I apply the name Fomes 

 carneus granularis n. var. ' ' 



This species is quite common on larch, pine and spruce logs. Locali- 

 ties: Milwaukee, Hazelhurst, Star Lake, Shanagolden and Ladysmith. 

 Largest specimen 10 cm. wide, 8 cm. long and 8 mm. thick. 



The species differs from F. roseus, whose color and substance are 

 about the same, by being thinner, very much imbricated and laterally 

 confluent, and its lack of the horny crust that is found in old specimens 

 of F. roseus. 



F. carneus Nees subzonatus Pk. 



This variety as described above by Peck, is also quite common. 



Our specimens of the above two species agree well with the descrip- 

 tions, still I am inclined to question whether F. carneus may not be 

 merely a variety of F. roseus. 



Fomes ungulatus (Schaeff.) Sacc. (Plate V, fig. 24 a and b; Plate 



VIII fig. 28.) 



Pileus ungulate, 10 to 12 cm. broad, thick, concentrically sulcate, ru- 

 fous to ochraceous, subzonate, rugulose (not at all varnished) ; margin 

 yellowish-tawny ; pores minute, short, whitish-yellow. 



Saccardo (26, VI, p. 126) says: ''perhaps an ungulate, sulcate-zonate 

 variety of the preceding. " (Fomes pinicola). 



I include here most of the forms which Peck, Von Schrenk and others 

 have included under F. pinicola Fries. 



Writing of F. pinicola Fries, Peck (22, 54, p. 169) says: "This spe- 

 c-ies is very common in the Adirondack region, growing on old trunks 

 of coniferous trees. If rightly limited it is a most variable species not 

 only in shape and color but also in size. It is usually 7.5 to 12.5 cm. 

 in diameter, but sometimes much larger. Two specimens were found
