THE GENUS CYCLOMYCES. 



This genus is based on the concentric disposition of the pores. 

 With the exception of a few on the outer circles, they take a lamellate 

 form and then the genus can be briefly characterized as being Len- 

 zites with the lamellae concentric instead of radiate. It is a rare 

 genus, occurring only as far as known in the United States, the East 

 Indies, and African Islands. The genus was first described by Fries 13 

 in 1830, and a fairly good cut given of it. 14 It consists (as I believe) 

 of only two species, Cyclomyces fuscus and Cyclomyces Greenii. 

 These two species have different context and are put in different 

 genera by those who give preference to other than hymenial char- 

 acters. 15 The curious, concentric disposition of the pores (and 

 lamellae) is a very prominent and seems to me to be a good char- 

 acter on which to base a genus.

14 It can hardly be said to be correctly described, however, as he states "Asci immersed, 

 free, as in Polyporus." 



13 In brief, Cyclomyces fu.-cus has abundant, colored setae and hyaline 



epixylous. Cyclomyces Greenii has no setae and colored spores, ?nd grows in the ground.
