previous lists, the latter containing ioi names. A few new 
species are described, and new combinations proposed. The au¬ 
thor referring to such names as P. “caricis-asteris”, P. “caricis- 
erigerontis” says: “As it is becoming evident that there are a 
number of species of Rusts on Carices this method of forming 
specific names from the generic names of both Aecidial and Rust 
hosts would, if carried out be of much assistance in understand¬ 
ing them.” This is a good hint, practical in some cases — but 
of course the license could not be sanctioned for throwing aside 
heretofore published names or combinations framed in accord 
with the accepted usage. 
A very Comprehensive Treatise on t&e Fungous Dis¬ 
eases of Grasses is that by L. H. Pammel and J. B. Weems in 
the Iowa Geological Survey, Bulletin i (pp. 185-292, 1901). 
Historical and descriptive notes are given of all the common fungi 
occurring on the native and cultivated grasses. Very many text 
figures and plates add much to the value of the article, which will 
prove very useful to beginners and amateurs, and even to pro¬ 
fessional botanists. The date in the preface shows that it was 
completed in 1899, but evidently there was considerable delay in 
publication. Consequently the nomenclature is not always such 
as the American mycologists use to-day. 
Dott. C. Massalonga in Note Micologiche published in 
Malphigia, An, XVII, Fasc. IX. pp. 419-423, discusses the follow¬ 
ing: (1) Sulla causa di un precoce disseccamento delle foglie 
di Quercus pubescens Willd. (with -description of Gloeosporium 
nervicolum C. Massal. in litt.) ; (2) Sull antracnosi delle foglie 
di Populus tremula L.; (3) Di un ifomicete che vive parassita 
sul tallo di Candelaria vulgaris A. Massal. (with description of 
Fusarium lechenicolum C. Massal. in litt.) 
Tilletia in the capsule of Bryophytes is the title of a 
note by Bradley M. Davis, Botanical Gazette, 36:306-7, Oct. 1903. 
He calls attention to the fact that the capsules of certain mosses 
and liverworts are sometimes attacked by fungous parasites that 
fill these structures with a mass of mycelium, which develops 
small spores as in the Ustilaginales. In 1892 Nawaschin de¬ 
scribed such an organism under the name Tilletia ( ?) sphagni. 
The author refers to Sydow’s recent Tilletia ( ?) abscondita, in 
the sporophyte of Anthoceros dichotomus, and says that “Botan¬ 
ists are probably not aware that the liverwort, Ricciocarpus na- 
tans, harbors a parasite which appears to be similar to this Til¬ 
letia (?) described in the other bryophytes.”
