sterile margin, which does not curl in drying. But from this it 

 varies in numerous ways forming intermediate series that connect 

 it so closely with other species, particularly H. scrobiculatum, that 

 it is very difficult to say where the line should be drawn between 

 them. The plant should receive careful field study, and its vari- 

 ations noted, especially in single gatherings, where there is reason 

 to believe the plants have all sprung from a common mycelium.

24- Hydnum coriaceo-membranaceum Schweinitz, Syn. N. A. 



Fung. 162. 1834 



Type Loc. : Bethlehem, Pa. (Schweinitz). 



This plant has never been reported since Schweinitz described 

 it. The type specimen in the Schweinitz collection in the Phila- 

 delphia Academy of Science is unfortunately totally destroyed 

 Berkeley and Curtis, who saw the specimen in 1855, reported that 

 it was "a very singular and distinct species M in their commmen- 

 tary on the Syn. Fung. Amer. Bor.* Schweinitz himself remarks 

 " distinctissima species." It would be especially interesting if 

 this apparently clearly marked species could be rediscovered. 

 The original description is added, therefore, as it is not generally 

 accessible.
