Mycologia 



Polyporus arcularius. Frequent on fallen sticks. 

 Polyporns elegans. 

 Poronidulus conchifer. 



Pycnoporus cinnabarinus. On oak fence rails, — an uncommon host. 

 Tyromyces lacteus. 



Tyromyces semipileatus. On a white oak log. 



6. Boletaceae 



Ceriomyces affinis. Found twice. 

 Ceriomyces bicolor. 

 Ceriomyces chromapes. 

 Ceriomyces communis. Abundant. 



Ceriomyces edulis. Found a few times, — the brown form only. 

 Ceriomyces fumosipes. Found once or twice. 



Ceriomyces griseus. Found several times, usually growing alone, but once 

 near C. retipes. The species is very distinct from C. retipes and is never 

 bitter, even in old plants. 



Ceriomyces retipes. Several beautiful yellow specimens were found in oak 

 groves, none of them resembling C. ornatipes in color, and all of them very 

 distinct from C. griseus. Careful observations were made on all specimens 

 found, and it was established beyond a doubt that C. retipes is decidedly 

 bitter in all stages and therefore unfit for food, while C. griseus is edible. 

 The stipe is much the same in both species but in C. griseus the reticula- 

 tions are smaller and more shallow. The tubes; flesh, and surface, as well 

 as taste, are decidedly different in the two plants. 



Ceriomyces subglabripes. Found two or three times in grassy oak woods. 

 Pileus reddish-fulvous, glabrous, rugose ; flesh lemon-yellow, with taste re- 

 minding one of potassium nitrate ; tubes and stipe also lemon-yellow. 



Ceriomyces sp. Gregarious under white oaks. Fulvous, rugose, 7-10 cm. in 

 diameter ; context nutty, white, becoming skin-colored when bruised ; tubes 

 lemon-yellow, browning when bruised; stipe yellowish, chaffy, 10-12 X 2-2^2 

 cm. Characterized by numerous scurfy particles on the stipe. I found 

 upon my return that Dr. Coker had recently collected this same species in 

 North Carolina, so I have suggested that he name it and include the Blacks- 

 burg locality. 



Rostkovites granulatus. 



Strobilomyces strobilaceus. Frequent. 



Suillellus luridus. Abundant. 



Tylopilus felleus. Very common and large. One group was practically white, 



growing in an opening in the woods. Could they have been bleached? 

 Tylopilus gracilis. 



7. Agaricaceae 



Agaricus sp. Only two specimens were found and these were solitary at 



different points in oak groves. 

 Armillaria putrida. Found - only once. 

 Chanterel Chantarellus. Abundant. 

 Chanterel floccosus.
