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 Agaricus.and the daedaleoid forms of Porodacdalca.

Lenzitina Karst. Finlands Basidsv. 337. 1889. 

 Type : Sesia hirsuta (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 Gloeophyllum, as follows: 



Species : Gloeophyllum hirsutum (Schaeff.) Murr., Gloeophyl- 

 lum Berkeleyi (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. 1904 



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 of 

 his genus Xanthochrous (Ann. Bot. Buitenz. First Suppl. 1 13. 



1897).
