WESTERN POLYPORES 



8. SCUTIGER. 

 7. POLYPORUS. 



9. AURANTIPORELLUS. 



10. PYCNOPORELLUS. 

 it. PYCNOPORUS. 

 12. LAETIPORUS. 



Hymenophore stipitate. 



Plants fleshy, terrestrial. 

 Plants tough, epixylous. 

 Context bright-colored, yellow or red; hymenophore 



sessile. 

 Pores red or reddish. 



Context soft and spongy. 

 Context firm. 



Tubes fragile; surface anoderm. 

 Tubes firm and regular; surface pelliculose. 

 Pores yellow; plants very large. 

 Context brown. 



Hymenophore sessile. 

 Spores hyaline. 



Context light-brown. 



Context at first fleshy, becoming slightly 



corky. 



Context tough from the first. 

 Surface glabrous or nearly so. 

 Surface distinctly hairy. 

 Context dark-brown, friable. 

 Spores brown. 

 Hymenophore stipitate. 

 Spores hyaline. 

 Spores brown. 



Tribe 2. Volvatae. Hymenophore corky to woody, annual; surface smooth, 

 encrusted; context corky; tubes cylindric, concealed at first by a volva, which is 

 perforated at one or more points at maturity; spores hyaline. 



Pileus sessile, subglobose, white or slightly reddish-brown. 19. CRYPTOPORUS. 



Tribe 3. FOMITEAE. Hymenophore large, woody, perennial, rarely small or 

 annual; surface anoderm or encrusted, usually sulcate, sometimes varnished; 

 context punky or woody, variously colored; tubes cylindric, usually thick- 

 walled; spores rounded, smooth or verrucose, hyaline or brown; cystidia fre- 

 quently present; surface of pileus conidia-bearing in a few species; stipe rarely 

 present, the hymenophore usually being sufficiently elevated by its host. 

 Annual forms and species in a few genera connect this group with the Poly- 

 poreae; while the tendency at times to produce a daedaleoid hymenium, shown 

 especially in Porodaedalea, connects it with the Daedaleae.
