Preface 



Since the publication of Bulletin No. 3, on the Hymeniales of 

 Connecticut, the writer has continued investigations on fleshy and 

 woody fungi, confining his aftention more especially, however, to 

 the edible species of the Agaricacecc. The results of the study 

 of this group of plants form the basis of Parts I and II of 

 this report. 



In Part I may be found keys to the Connecticut species of 

 Agaricacecc. These keys are based upon the author's observa- 

 tions and notes; but, in some cases where specimens have not 

 been personally collected, original descriptions have been used. 

 Keys to the genera of Agaricacece may be found on pages 17, 

 18, 19, and 20, Bulletin No. 3, of the State Geological and 

 Natural History Survey. Descriptions of the genera may also 

 be found in the same Bulletin. 



Part II considers in detail the chief characters of some edible 

 species of mushrooms. 



Part III consists of a list of species of Hymeniales not 

 reported in Bulletin No. 3. Some of these species have been 

 collected by the late Dr. L. F. Underwood and by Dr. F. C. 

 Earle in Redding and vicinity, and these specimens may be 

 found in the Cryptogamic Herbarium of Columbia University at 

 Bronx Park, N. Y. Mr. C. C. Hanmer of East Hartford has 

 continued collecting, and has kindly contributed the results of 

 his work to this report. The writer has collected in Mansfield 

 and vicinity. Fifty-three species not before reported from the 

 state are here listed. 



The specimens collected by the writer during the last three 

 years, as well as many of those previously collected, were com- 

 pared with many type specimens in the Cryptogamic Herbarium 

 of Harvard University. The writer wishes to express his deep 

 appreciation of the assistance given him in this work by Dr. 

 W. G. Farlow and Dr. A. F. Seymour of the Department of 

 Cr}^ptogamic Botany of Harvard University. Several weeks
