72 THE POLYPORACEAE OF WISCONSIN. 



Fomes roseus (Alb. & Schw.) Fries. 



Pileus suberose-lignose, hard, triquetrous, smooth, clustered, within 

 and without rose-color, the color obscured without by a grayish-black 

 bloom, within floccoso-fibrous ; pores minute, rotund, concolorous ; spores 

 6 microns long. 



"Pileus 5 — 12 cm. broad, base 1 — 3 cm. thick. Subcespitose. Poria 

 stalactites Hoffm. is a subterranean monstrosity of this fungus.'" 

 Saccardo (26, VI, p. 189). 



Common. Found chiefly on tamarack, hemlock, spruce and pine. 

 Localities: Hazelhurst, Shanagolden, Star Lake, Crandon, Ladysmith, 

 Brule, Horicon and Blue Mounds. Largest specimen 6 cm. broad, 3 cm. 

 long, 2 cm. thick. The pileus is hard-corky, glabrous, smoky, or gray- 

 ish-black toward the base, the rose tints becoming more and more 

 marked toward the margin. The substance is fibrous-corky, pale rose- 

 color, as are also the tubes. Pores small with obtuse dissepiments, tub- 

 ules stratified. This species is closely related to F. carneus Nees, from 

 which it may be distinguished by the hard, smooth, ungulate pileus. 

 The flesh and tubes are of a slightly paler color. 



Peck (22, Kept, 54, p. 154) gives further notes on F. roseus as fol- 

 lows : ' ' The pores have nearly the same color, and size as in F. carneus 

 and the young pileus and newly grown margin also resemble those of 

 F. carneus in color, but the shape of the pileus is different. It is 

 thicker, triquetrous or ungulate, not imbricate, nor laterally confluent, 

 the surface more even and covered with a corneous crust after the first 

 year. The pileus becomes blackish or cinereous and is somewhat marked 

 by concentric furrows or depressions showing the limits of the yearly 

 increments. The substance is similar to that of F. carneus, but the 

 color is slightly paler."

Fomes carneus Nees. 



Pileus effuso-reflexed, lignose, hard, thin, rugose, glabrous, azonate, 

 carneus or flesh-colored, concolorous within; pores minute, round de- 

 current at the base. 



Pilei longitudinally effused, imbricate, rarely solitary, 8 to 10 em. 

 long, 2.5 to 4 cm. broad, 5 to 7 mm. thick. 



Peck (22, Kept. 54, p. 169) makes the following observations on this 

 species: "Very abundant on decaying trunks of spruce trees in Adi- 

 rondack region. It is perennial, the upper surface of the pileus gen-
