192 JOUENAL OF THE MiTCHELL SoCIETY [March 



The large, thin zonate cap and very short spines are strikingly similar. 

 The spores also are the same as in our plants, averaging about 4.5m 

 in diameter. Some of the ]^ew Jersey plants are strongly infundi- 

 buliform. Beardslee's plants, which he refers to H. infundihulum, 

 seem the same as mine.

Genus Phellodon. 



This genus is like Hydnellum except that the spores are papillate 

 or echinulate instead of warted. For all practical purposes it would

 cause Banker is describing a new species and prefers to recognize 

 the genus.
