gills though the spores are white. A full-page plate in the Bul¬ 
letin gives a good idea of the appearance of this Clitocybe. 
A List of Species of Fungi, Hymenomycetes, Gastromy- 
cetes, and Ascomycetes, by Jennie F. Conant, is given in a four- 
page Bulletin (No. 19) of the Boston Mycological Club, issued 
Feb. 5, 1903, which represents the collection by members, ex¬ 
hibited at the Horticultural Hall, Boston, during the year 1902. 
The interesting list is too long to count — say over three hun¬ 
dred species. 
A Rosette Disease of Potatoes, attributed to the sterile 
fungus Rhizoctonia, is the title of Bulletin 139, Ohio Agr. Exp. 
Sta., April 1903. Perhaps guilty but not proved would express 
the attitude of mind of the author of the Bulletin — at least he 
says “The sterile fungus, Rhizoctonia, is indicated as the cause 
in the instances stated, by the constant presence and a high de¬ 
gree of probability attaches to this indication/’ A list of some 
articles relating to diseases of the Potato attributed to Rhizoc¬ 
tonia includes twenty items chronologically, arranged the dates 
being 1858-9 to 1902. 
Contributions from the Cryptogamic Laboratory of 
Harvard University, LV, by R. Thaxter, consists of Myco¬ 
logical Notes, 1-2, namely, A New England Choanephora (de¬ 
scribed by Berkeley in 1875 under the name of Rhopalomyces 
cucurbitarum), and Notes on Monoblepharis. Objection is en¬ 
tered against dividing the latter into genera (or even subgenera) 
which Lagerheim has proposed. A Key is appended for the six 
species of this alga-like genus Monoblepharis. This No. of the 
contributions appears in Rhodora, 5: 97-108. April 1903. 
A Minnesota Species of Tuber, namely Tuber lyoni, is 
reported by Fred K. Butters, in the June No. (1903) of the Bo¬ 
tanical Gazette (pp. 427-31). The specimens were found March 
11, in the leaf-mould about the base of small group of Bass-wood 
trees, in a mature condition, doubtless formed late in the previous 
autumn. 
Tpie More Important Diseases of Forage Plants as 
given by David Griffiths in Forage Conditions and Problems of 
Eastern Washington and Adjacent Regions, U. S. Department of 
Agriculture, Bureau of Plant Industry, No. 38 (pp. 43-4), are 
caused by the following Smuts: Ustilago hypodites, U. scolo- 
chloa, U. bromivora, U. striseformis, and Tilletia fusca. This 
class of parasitic fungi injures more (the author states) than 
one would suppose, the development of native economic plants. 
Reference is made in one case to meadows of the valuable Spran- 
gle-top (Scolochloa festucacea), “in which one-half to two-thirds 
of the vegetation consisted of this grass, and one-half of the 
plants were smutted.”
