294 BOTANICAL GAZETTE [APRIL 
Dr. Thomas Taylor” of a work on mushrooms, with colored plates of reason- 
ably good quality, will doubtless meet with an appreciative response. Dr, 
Taylor was for many years the microscopist of the United States Department 
of Agriculture, and the readers of this journal do not need to be told the 
character of his work. In this official capacity he issued a number of reports 
on mushrooms, which have furnished some of the material for the present 
series. 
Although the subject is not treated in a sufficiently systematic way prop- 
erly to entitle the work to the name of “handbook,” and in spite of some 
irrelevant matter, the mycophagist will yet find much in these pages to help 
him.— J. C. A.
