to a Knowledge of the Hydnaceae 209 



New Jersey (Gentry). Reported also from Pennsylvania 

 •(Schweinitz) and North Carolina (Curtis). The Schweinitzian 

 specimen now in the Philadelphia Academy of Science is nearly 

 destroyed so that its characters can not be determined. Curtis' 

 specimen I have not seen. It seems doubtful if the plant is com- 

 mon with us. Most of the specimens referred here in the collec- 

 tions are evidently something quite different. I have seen but 

 one specimen (Gentry's) that appeared to have just claim to being 

 regarded as this species. 



There seems to be no little uncertainty among authors con- 

 cerning this plant. Descriptions vary greatly ; Barla's figure 

 seems to depict a very different plant from Swartz' and Bresa- 

 dola's figure is doubtful. The chief distinctive characteristic of the 



plant is the thick, fleshy, regular, glabrous pileus, 5-15 cm. wide, 

 by no means repand. Saccardo says, "spores 10-15 fi long." 



In view of the uncertainty that seems to prevail concerning 

 this plant and as Svvartz's original description is often inaccessible, 



2 t is quoted in full.
