SAPROPHYTIC FUNGI OF EASTERN IOWA. y 



We have seen but a single specimen, from Mr. Holway, 

 Decorah. It agrees so well with the description as to leave 

 no doubt as to identity. The species is said to have the 

 habit of PajiHS sfipticiis, i. e., it occurs in little densely cespi- 

 tose tufts. It is also said to be common in its wide range, 

 from New England to Borneo. 



Our specimen is about 2 cm in each extent, stipe about 

 6 mm long. 



V. CYCLOMYCES. 



Pileus coriaceous-membranaceous with stipe central or lat- 

 eral, or sometimes resupinate, velutine, fuscous or cinnamon; 

 lamellae, concentrically arranged, never radiating. 



Referred to the Polyporeai and not to the Agaricinege 

 chiefly because of the marginal pores from which seem to be 

 characteristic. 



I. Cyclomyces greenii Berkeley. 



Pileus orbicular, undulate, sublobate, zonate tomentose, 

 cinnamon, marked with a few furrows near the edge; stipe 

 central, obconic; lamellae thin, acute, at length ashy. 



A fungus very remarkable in more wa3-s than one. The 

 concentric lamella? are very curious and beautiful. The whole 

 sporocarp is obconic or turbinate and except the ashen lamella?, 

 rich brown in color, softly velutine above. 



Rare, one specimen only so far collected. On the ground 

 in mossv woodland. Iowa City. 



VI. D.^ DALE A. 



Pileus generally dimidiate, sometimes reflex-resupinate, 

 corky, leathery, persistent. Substance of the pileus descend- 

 ing unchanged into the trama. Pores elongate, labyrinthi- 

 form i. e., tortuous winding, limited by correspondent dry 

 winding lamella?. 



A difficult genus midway between Tramctes and Lenzites. 

 From the first it differs in the more elongate winding pores; 

 in Lenzites the lamellcC anastomose but little. Our few spe- 

 cies are perhaps easily recognized.
