MURRILL : POLYPORACEAE OF NORTH AMERICA 355 



Antrodia mollis Karst. Medd. Soc. Faun, et Fl. Fenn. 5 : 40. 



1879- 

 Tramctes stereoides Bres. Att. I. R. Accad. Sc. ed Art. III. 3 : 92. 



1897. 



According to Bresadola, this species is the same as Poly- 



porns stereoides Fr. (Obs. Myc. 2: 258. 18 18), described from 



very small specimens collected on old fir trunks in Sweden, but 



different from Polyporus cerviuus of Persoon (Myc. Eur. 2 : 87. 



1825). 



The plant is fairly well known in Europe and temperate North 

 America on decaying wood of beech, maple, linden and other de- 

 ciduous trees : Finland, Karsten ; Hungary, Kmct ; Tyrol, Bresa- 

 dola ; Canada, Ellis, Macoun, Dearness ; Maine, Blake; New 

 York, Peck ; Ohio, Lloyd. 



3. FAVOLUS Beauv. Fl. Owar 1 : 1. pi. 1. 1805

 Sccnidium Kuntze, Revis. Gen. 515. 1893. 



Type : Favolus hirtus Beauv. 



Hymenophore small, annual, epixylous, sessile, dimidiate or 

 reniform ; surface multizonate, margin thin : context thin, leathery, 

 pallid or brown ; tubes alveolar : spores smooth, hyaline. 



Species : F. tenuis (Hook.) Murr., F. variegatus (Berk.) Murr. 

 [see Bull. Torrey Club 32: 99-103. 1905]. Although typ- 

 ically white-fleshed, this genus contains brown forms and F. vari- 

 egatus is usually brown.

Type : Hapalopilus rutilans (Pers.) Murr. 



Hymenophore annual, very rarely perennial in the tropics, 

 epixylous, sessile, dimidiate, simple or imbricate ; surface anoderm, 

 rarely pelliculose, zonate or azonate, usually brown and glabrous : 

 context brown, leathery or corky, tough or rarely friable when 

 dry ; hymenium usually differently colored, tubes small, thin- 

 walled : spores small, usually ovoid, hyaline. 



Species : H. rutilans (Pers.) Murr., H. sublilacinus (Ell. & Ev.) 



Murr., H. licuoidcs (Mont.) Murr., H. gilvus (Schw.) Murr., H. 



fidvitinctus (B. & C.) Murr., H. hispidulus (B. & C.) Murr. [see
