particulars but much thinner, smaller and more widely effused. 

 N. A. F. 6. 



7. Poi.YPORUS FUMOSus {^Pevsooii) Fries. 



Pileus fleshy, cork}^ azonate, sericeous becoming glabrate, 

 sooty-pallid, dilate-adnate behind, within fibrose, sub-zonate; 

 pores small, short, round, entire, whitish-smoky, becoming 

 darker if rubbed. 



Much like No. 5 in color and general shape, but thick, corky» 

 pallid, showing sooty or smoky tints chiefly where bruised or 

 rubbed. 



8. POLYPORUS FRAGRANS Pcck. 



Pileus fleshy, tough, effuso-reflexed imbricate, 2^-5 cm 

 long 5-10 cm wide, rather thin, but sometimes thickened at 

 the base, velvety to the touch, clothed with minute innate 

 tomentum; margin thin, sometimes sterile; context sub-fibrous^ 

 zonate; pores minute, unequal, angulate, the dissepiments thin,. 

 acute, dentate or lacerate, whitish, duller with age and darker 

 when bruised. 



Very near the preceding, but distinguished by its larger 

 and especially unequal denticulate pores. When fresh the 

 pleasing odor is characteristic. Rare. 



9. PoLYPORUS GiLVUS Schzueiuitz. 



Pileus corky, woody, dimidiate-sessile or effused behind, 

 yellow-ferruginous, azonate, rough, uneven, the margin tomen- 

 tose, acute; pores very small, crowded, entire, brownish^ 

 changeable; context yellow-ferruginous. 



Very common, chiefly on oak, and very variable. Some- 

 times thin, effused, almost resupinate, it anon assumes dimidi- 

 ate, imbricate form extending up and down a limb bracket- 

 fashion, for several inches. The pilei are sometimes thin, the 

 margin abruptly deflexed, and then again are thick, almost 

 triangular in section, sometimes rough and sometimes smooth 

 and sometimes obscurely zonate. Withal persists the peculiar 

 pale yellowish-ferruginous context which is not Hke the color 

 of anything else in this parish.
