tional treatises, he published a number of papers on cytological, morphologi- 
cal, physiological, and phylogenetic subjects. His main work, however, 
was devoted to the systematic study of cryptogams, especially of fungi. 
In 1890 he published in the Annals of Botany a "Monograph of the Lemanea- 
ceae of the United States," of which he had in preparation a revision. 
This monograph and a ''Note on Entothrix grande Wolle," published in 
the Botanical Gazette (1892), were his only papers on algae. 
While stationed in the Carolinas and in Alabama, his work naturally 
was concerned with the local species, for the most part those which attack 
important crops, especially cotton, and for some years after he removed to 
Cornell he prepared bulletins, issued by the Experiment Station, on in- 
jurious fungi, of which Bulletin No. 73 (1894) and No. 94 (1895) were 
among the most elaborate. 
But even while in Alabama and the Carolinas, his preference for purely 
systematic studies was manifest, as shown by his papers on Cercospora and 
Ravenelia from Alabama, Erysipheae from Carolina and Alabama and, in 
connection with von Schrenk, on "Some Fungi of Blowing Rock, North 
Carolina." 
The "Studies and Illustrations of Mushrooms Edible and Poisonous," 
Cornell Bulletins 138 and 168 (1897, 1899) were the forerunners of the 
book "Mushrooms Edible and Poisonous" (1901), with many excellent 
photographic illustrations made by the author, the work through which 
Atkinson is best known to the general public. In recent years Atkinson 
had limited his work more and more to a minute study of the development 
of the carpophores of the higher Agaricaceae and to a systematic revision 
of certain genera. He was devoting himself to the preparation of an exten- 
sive illustrated work on the "Fleshy Fungi of North America," for which 
he was exceptionally well equipped. While in the South he was able to 
gain a practical knowledge of the interesting fungi of this region, and at 
Cornell was in a position to familiarize himself by frequent excursions with 
the very rich and varied mycologic flora of the environs of Ithaca. Through 
his personal acquaintance with Peck he was able to acquire a detailed knowl- 
edge of the fungi of New York such as could be obtained only by word of 
mouth. He had also been able to visit the most important mycological 
herbaria of Europe, and had made it a rule to botanize in regions where 
well-known mycologists had worked, that he might see living specimenis of 
the species described in their publications and thus be better able to compare 
them with species known to him in America. 
It is greatly to be regretted that the important work for which he was 
so well equipped, and for which he had accumulated such extensive material, 
including several thousand remarkable photographs, should have been 
brought suddenly to an end when, from his age and robust health, he had 
every reason to look forward to its successful completion.
