To one who by this time contemplates the serious study and the identification 

 of all the species, numerous generic treatises and a large and ever growing 

 library and a microscope soon loom up as coveted necessities. 



Among the chief additional monographs I like to have at my elbow in 

 field work, such for example as I keep in my camp in Canada, are : Burlingham 

 on Russula and Lactarius; Beardslee on Russula and Mycena; Coker on 

 Amanita, Hydnaccae, Clavariaceae, and Lactarius; Coker and Beardslee on 

 Collybia, Laccaria, and Clitocybe ; Murrill on the Polyporcs of North America ; 

 Harper on Pholiota, Stropharia, Hypholoma, Lentinus (developing the group 

 idea in the analysis of our gill fungi) ; Ilicken on Blatterpilze (color plates 

 very poor) ; Carleton Eea on the Basidiomycetes of Great Britain; Macbride 

 on Myxomycetes; Burt on Thelephoraceae, Clavaria, and Merulius; Lange 

 on Mycena, Lepiota, Coprinus; Quelet and Bataille on Amanita; Bataille on 

 Lactarius, Eussula, Cortinarius, Inocybe, Morchella, and Helvella; Lloyd on 

 the Gastromycetes and Polyporaceae ; and Peck on Lycoperdon (a valuable 

 analysis in his thirtj'-second report). Kauifman's Agaricaceae of Michigan 

 contains a series of monographs, noting especially Cortinarius and Inocybe, 

 and Pennington's chapter on Coprinus. 



In December, 1918, I succeeded in securing the services of Louis C. C. 

 Krieger, artist and mj-cologist, trained for ten years imder that late lamented 

 master, Professor Wm. G. Farlow, of Harvard. As the subsequent develop- 

 ment of my library, paintings, and collection of fungi is due to Mr. Krieger's 

 fostering care, I refer in some detail to his work. 



His first training, obtained in Baltimore and at the Royal Academy of 

 Fine Arts, Munich, was as an artist, especially as a painter of portraits. An 

 interest in fungi began under Dr. Thomas Taylor in the United States 

 Government service, 1891-95, when he illustrated some of the government 

 publications. Following this came his decisive and fruitful Harvard experi- 

 ence, with the execution of some four hundred aquarelles of fungi and algae, 

 now in Farlow's collection along with his matchless library at Harvard 

 University, together with illustrations made by Bridgham. While working 

 on the fleshy fungi under Farlow, Krieger began a card catalogue at present 

 available in my library, covering this group and the polypores and consti- 

 tuting a most exhaustive analysis of the world's literature under several 

 captions; begun in 1902, this precious adjuvant in all research work now 

 numbers some four hundred thousand manuscript cards. The Krieger
