THE HYDNUMS OF jSTOETH CAROLIlSrA 



By W. C. Coker 



Fungi with the hymenium borne on distinct spine-like teeth wjiicli 

 are typically terete and pointed, and hang vertically. Plant body 

 upright with a distinct stem and cap, or laterally sessile, or the teeth 

 attached to a resupinate stratum; texture varying from fleshy and 

 brittle to tough and pliable. Spores white to brown, smooth or tuber- 

 culate or papillate or echinulate. Growing on earth, leaf mold, de- 

 caying wood, or injured living trees. Many are edible and none are 

 known to be poisonous. With one exception, the plants here treated 

 include only such as belong to the genera Hydnum and Phaeodon in 

 the sense of Hennings (Engier and Prantl's Pflanzenfamilien. Leip- 

 zich. 1900). The family Hydnaceae is now broken up into a large 

 number of genera, including many inconspicuous resupinate plants. 

 In some the teeth are mere knobs or papillae in others they are iiiore 

 or less flattened or fused and vary towards the Polyporaceae. With 

 the exception of Hydnochaete, all such are here omitted. For special 

 studies of the genera here treated as well as of other smaller and less 

 conspicuous genera of the family, see the following papers bv Dr.

Dr. Banker has with Rrent kindness and patience looked over a considerable number of 

 my collections, and I take pleasure in acknowledffinc: his very helpful advice. As I have not 

 always followed his opinion, ho must not be thoueht responsible for any of the errors. 



Tlie two jdates in color are from paintinRS by my niece, (iladvs Coker; the iihotograph-i 

 are all by me excejjt that of Phellodon alboniger which is by Beardslee. All are natural size 

 unless otherwise indicated. The spore drawings are all by me, with a magnification of 2160 

 They have been inked in by several members of the laboratory staff.
