220 Banker: .A preliminary Contribution 



plant he described, we are left not only in doubt, but in some con- 

 fusion as to what plant Persoon may have had in mind. A plant 

 from Alabama, in the Underwood collection, conforms quite 

 closely to Persoon' s description and resembles in form Schaeffer's 

 figures, but does not correspond to any known European plant. 

 It is doubtful, therefore, whether it should be regarded as H. 

 compaction Pers. Moreover, it does not show the blue variega- 

 tions mentioned by Fries, a characteristic which is quite evident in 

 some of the European specimens. I have not seen Curtis's speci- 

 mens, while Schweinitz's plant as preserved at Philadelphia is very 

 curious and distinct from anything I have seen. I believe we have 

 several unique species in this country passing under the name of 

 H. compaction. 



33. Hydnum cinereum Bull. Herbier de la France, 309. I79 1 



Icon.: Bulliard Herbier de la France, pi. 419 !; Sicard, Hist, 

 nat. Champ, pi. §8. f. 297. 



Type Loc: European. 



Bethlehem, Pa. (Schweinitz). Has been reported only by 

 Schweinitz and his specimen is too uncertain to draw any conclu- 

 sions. In the absence of actual specimens it is impossible to sat- 

 isfactorily locate this plant. It is doubtful if this species has 

 really been found here. 



34. Hydnum mirabile Fries, Monog. 2: 349. 1863 



Icon.: Fries, Icon. Sel 

 Type Loc: European. 

 Port Jefferson, N. Y. ( 



/* J./ 



Peck). This species has been reported 

 only by Peck and he expresses doubt as to whether his specimen 

 is rightly referred here. The plant is characterized by a peculiar 

 woolly tomentum covering the entire plant. 



35. Hydnum velutinum Fries, Sys. Myc. 1 : 404. 182 1 



Type Loc. : European. 



All specimens reported as H. vel\ 



i have proven to be H. spongiosis

latter species has been generally referred to velutinum. Curtis' s 

 North Carolina specimen has not been seen.
