SPORES HYALINE. SETAE PRESENT. 



FOMES BOREALIS. Pileus ungulate, with a thin, pale, smooth, hard 

 crust, variegated with darker spots. Context hard, dark brown (Amber brown). 

 Setae slender, numerous, dense. Spores hyaline, globose, 6 mic. 



I found this on the birch at Temagami, Ontario. It is closely related to ig- 

 niarius and nigricans. The marked feature is the dense setae on the hymenium.

Fomes squarrosus. 



FOMES SQUARROSUS (Fig. 590). Pileus ungulate, with*! a 

 black, rough, rimose crust. Context hard, dark brown (Antique 

 brown). Pores minute, round, with concolorous mouths. Pore layers 

 indistinct. Setae few, slender. Spores hyaline, globose, 4 mic. 



This specimen was sent by Rev. James Wilson, Victoria, Aus- 

 tralia, but the host was not stated. Mr. Wilson sends also a fine 

 photograph (Fig. 590). When received I supposed it to be Fomes 

 rimosus, also a common species in Australia, and the photograph 

 would represent either species. The context color also is similar, but 

 the microscopic character, as will be noted above, are entirely differ- 

 ent. This is a large species, the photograph being reduced to about 

 one-third. 



FOMES ZELANDICUS. Pileus applanate, with thin, brown, 

 smooth, zonate crust. Context reddish brown (near Sanford brown). 

 Pores small, concolorous, with velutinate mouths. Setae abundant, 

 with slightly swollen bases, projecting 16 mic. Spores not found, 

 doubtless white. Hymenial cells white. 



I think this is known only from New Zealand and Pacific Islands. 

 The surface reminds me of that of Polyporus licnoides. The fungus 

 in its main features, setae and velutinate pore mouths, recalls Fomes 

 senex. 



Compare Hohnelii.
