The identity of Oidium Tuckeri with the conidial form of TJncinula 
spiralis was established by comparison of specimens from France and 
America. —Effif, A. Southworth. 
Briosi and Gayar a. Fung hi parassiti delle piante coltivate od utile , 
essiccati , delineati e descritti. The parasitic fungi of cultivated and 
useful plants. Specimens, illustrations, and descriptions. 
G. Briosi and F. Cavara, the mauagers of the Cryptogamic Lab¬ 
oratory at Pavia, Italy, anticipated the first fascicle of their collec¬ 
tion and descriptions of the parasitic fungi of cultivated and useful 
plants by a circular letter to possible subscribers, in which they state 
that the reasons which led them to make the collection was to place in 
the hands of farmers, schools, and agricultural colleges a publication 
which will present the necessary elements for the easy determination of 
the parasites infecting plants of economic value. 
This publication, they say, will consist of (1) specimens of plants at¬ 
tacked by parasitic fungi; (2) a drawing of the parasite and its organs 
of reproduction; (3) a short and accurate description of the fungus, 
accompanied by an indication of the remedies that have been sanc¬ 
tioned by experience. 
They state that this is the first publication of the kind that has ever 
been issued, and while its preparation requires no small amount of labor, 
it is undertaken in the hope that it will prove of practical value. 
The first fascicle has already been received by the Section, and proves 
to be all that was promised in the circular letter. The drawings are 
not elaborate, but clear, and convey a distinct idea of the fruit of the 
fungus, and these, combined with the descriptions and actual specimens, 
furnish sufficient data for the determination of any species contained 
in the collection. 
The text is Italian, and this will hinder many who are directly 7 inter¬ 
ested in agriculture from obtaining much profit from the work; but the 
species comprised in the first fascicle are mainly those which are com¬ 
mon in America as well as in Italy 7 . It seems to us that a good trans¬ 
lation would be of great practical value. There are twenty-five species 
in a fascicle, and each fascicle costs 7 lire in Italy and 8 ($1.57) in 
other countries. They are sent post paid, neatly put up.— Effie A.

Ward H. Marshall. A Lily disease. Annals of Botany, Yol. II., No. 
YII, pp. 319-382, with five double plates, GO figures. 
This paper is an important contribution to our knowledge of the biol¬ 
ogy of the form-genus commonly called Botrytis. 
Professor Ward has demonstrated that a Botrytis of the Polyactis type, 
found for a number of years on the spotting and rotting stems, leaves, 
and flower buds of Lilium candidum , is a true parasite and the cause of 
the disease. He established the uniform connection of the fungus with
