In Papers of the Michigan Academy of Sciences (23: 153. 

 1938) Dr. B. Kanouse calls attention to the fact that Feziza 

 sulphurella Peck and Peziza crucifera Phill. are identical. It is an 

 interesting coincidence that both were described in the same 

 month of the same year. Which name actually has priority it is 

 difficult to say. The above synonymy is based on the conclu- 

 sions of Dr. Kanouse.
