370 Murrill: Polyporaceae of North America 



the other hand, there is little to cause confusion between this 

 group and the Fomiteae, if we except the single distinctly perennial 

 species of Agarims and the daedaleoid forms of Porodaedalea.

 Type : Scsia Jiirsitta (Schaeff.) Murr. 



Lenzitina Karst. Finlands Basidsv. 337. 1889. 

 Type ; Sesia hirsiita (Schaeff) Murr. 



Hymenophore small, annual, epixylous, sessile ; surface hairy 

 or glabrous, anoderm, often zonate : context tough, brown ; 

 hymenium normally lamelloid or daedaleoid, but frequently 

 poroid in some species : spores smooth, hyaline. 



According to the rules now followed by most American 

 botanists Sesia must be replaced by Gloeophylhtm^ as follows: 



Species : Gloeophylhim hirsntiim (Schaeff.) Murr., Gloeophyl- 

 lum Berkeley! (Sacc.) Murr., Gloeophyllum striatum (Sw.) 



Murr., Gloeophyllum pallidofulvum (Berk.) Murr. [see Bull. 

 Torrey Club 31: 602-606. 1904]. 



2. CYCLOPORUS Murr. Bull Torrey Club 31 : 423. 19^4 



Type : Cycloporus Greenei (Berk.) Murr. 



Hymenophore annual, tough, anoderm, terrestrial, centrally 

 stipitate : context soft, spongy, ferruginous ; pores at first 

 polygonal, soon becoming continuous concentric furrows, dis- 

 sepiments thin, lamelloid : spores ovoid, smooth, ferruginous. 



In publishing the above genus I neglected to state that the 

 name had been previously used by Patouillard for a subgenus 01 

 Kis genus Xanthochroiis (Ann. Bot, Buitenz. First Suppl. US- 



1897).
