List of specimens received from the United States and Canada during the 

 ast four months of 1907, and a few that were crowded out of Letter No. 16. 



We list these specimens as they may be known to us, though we claim no 

 ritical knowledge of the subject other than concerning the Gastromycetes. We 

 ave, however, a general knowledge of the names of fungi that occur in American 

 terature. 



Our thanks are extended to those who have sent specimens, and we continue 

 j solicit specimens suitable for museum specimens, as per circular enclosed. 



Yours very truly,
