36. Hydnum concrescens Persoon, Obs. Myc. 1 : 74. 1796 



Type Loc. : European. 



North Carolina (Schweinitz). 



Schweinitz is the only one who has reported a species under 

 this name. Later in his Syn. N. A. Fung. 161 he referred the 

 same plant to H. cyathiforme Fr. As H. concrescens Pers. is a 

 doubtful species, and Fries himself afterward repudiated his own H. 

 cyathiforme \t is difficult to say what Schweinitz's plant may have 

 been. There is no specimen in his collection at Philadelphia. 



37. Hydnum Fennicum Karst. Rev. Myc. 9 : 10. 1887 



• Type Loc. : European. 



Port Jefferson, N. Y. (Peck) ; Kentucky (Morgan). 

 The American plants referred to this species are somewhat 

 doubtful but correspond closely to a specimen from Karsten him- 

 self which is preserved in the New York Botanical Garden. The 

 plant appears to be especially marked by a dark blue color at the 

 base of the stem. 



38. Hydnum spadiceum Persoon, Icon, et Disc. 34. 1798 



Icon.: Persoon, op. cit. pi. g.f. 1. 



Type Loc: European. 



Reported from Rhode Island (Bennett) and North Carolina 

 (Schweinitz). Schweinitz afterward regarded his specimen as 

 H. connatnm and Bennett's plant appears to have been destroyed. 



39. Hydnum connatum Schultz, Prodr. Flor. Starg. 491. 1806 



Type Loc: European. 



Reported from North Carolina (Schweinitz). The specimen 

 in the Acad. Nat. Sci. Phila. does not seem to differ from H. 

 scrobiculatum .
