which purports to cover the whole field of the British fungous flora, 
and to be a “classified text-book of mycology,” only half of the known 
species of fungi found in the region are included. However, the

_ AVALUABLE monograph upon the American species of Saprolegni- 
_ ew has recently been published by James E. Humphrey.’ It appears 
_ inthe Transactions of the American Philosophical Society, but has 
__ also been distributed separately. The group was greatly in need of 
study, and it is gratifying to have the labor so handsomely and so sub- 
_ Santiallydone. The author found little material upon which to be- 
 ginhis work, and with the exception of some aid froma half dozen col- 
: lectors, chiefly from the material gathered over ten years ago by Dr. 
William Trelease, he was dependent upon his own collections made 
during the two years given to the study. Considerable space is de- 
voted to the morphology of the group. Under the head of classifica- 
ton twenty-one species are described, belonging to seven genera. 
include six New species, while the study of European forms not 
yet found in America has led to the separation of a new genus, and 
change of name of two species. The seven lithographic plates are 
» and will be a great help in future study. This work
