ANOTHER NEW TRUFFLE 



W. A. MURRILL 



In the last number of Mycologia, Miss Gilkey described two 

 new American species of truffles, Tuber canaliculatum and T. 

 unicolor, the latter based on material recently collected in the 

 vicinity of New York City by the use of a dog trained in Europe. 

 After working over this New York material, Miss Gilkey ex- 

 amined and carefully compared with it some specimens collected 

 by Dr. Shear in Maryland twenty years ago, and pronounced them 

 similar but specifically distinct.

It therefore becomes my duty and privilege (since Dr. Shear 

 seems too diffident) to publish another new truffle from the 

 eastern United States; — and the task is an extremely easy 

 one. Dr. Shear collected the specimens, made the drawing here 

 published, and sent me his correspondence with Dr. Harkness
