SAPROPHYTIC FUNGI OF EASTERN IOWA. n 



azonate, ferruginous-fuscous, at length faded, margin acute; 

 pores rather large, rotund-angulate, concolorous with the 

 pileus, becoming fuscous with age; context wood-colored. 



Rather common; chiefly on stumps of Populus monilifera 

 and Acer sacc/ian'iiiiiii. Easily recognized by its seal-brown 

 covering of rather abundant harsh stiff hairs. The context in 

 well developed specimens is distincth' suberose within but 

 passes by imperceptible transitions into the matted hirsute 

 outer coat. In form our specimens are from crescentiform- 

 dimidiate to irregular, several inches long by an inch wide. 



VIII. FORI A. 



Fungi, resupinate and indeterminately effused; tubules form- 

 ing a stratum distinct from the hymenophore but not separ- 

 able nor stratose; the pileus obsolescent, ceraceous, coriaceous 

 or membranaceous. 



This genus has been erected simply for the reception of the 

 resupinate Polypores, and includes forms otherwise referable 

 to either of the succeeding genera. 



1. PORIA XANTIIOLOMA Schzucillitz . 



Widely but definitely effused, very thin, the margin mem- 

 branaceous-fimbriate. rather wide, elegantly luteous, sterile; 

 pores with rather thick walls, somewhat sinuous, pallid, minute. 



Not common, though spreading, when it does occur, as on 

 the underside of some leaning log, for many inches in the 

 form of long cream-colored ribbon-like patches. The pores 

 small, hardlv visible to the naked eye, quite thick-walled, 

 forming but a single thin stratum with little or no subiculum 

 visible. 



2. PoRiA SALMONicoLOR BcrkcIcy and Cooke. 

 Fructification entirely resupinate, arising from a thin white 



mycelium; pores at lirst subcarneous,then elongate, nigrescent. 



Such is the original brief description of a specimen sent by 



Ravenel from South Carolina. It is said to form strata several 



inches in extent. Our specimens are about eight cm long and
