ington, Mar. 10, 1892, pp. 66-77, pi. xi-xiv. 
Describes the extent of the disease and the stocks affecl ed. Gives an extended description 
of the general and special effects of the fungus, and discusses the spread of the disease. 
Gives general directions for prevention, mainly the collection and burning of fallen foliage 
and turning in the soil beneath the trees. Many details of germination and life history of 
the fungus are also given. The disease is due to Gercospora circumscissa Saco. (J.F.J.)

ton, Apr. 30, 1891, pp. 148-153, pi. xiv, xv. 
Refers to the presence of this disease in the Mediterranean region of Europe, and quotes 
description by Savastano. Probably due to presence of bacteria. Cutting off affected 
branches seems to be all that is necessary to movent disease spreading and doing damage.

6, 1891, pp. 107-110. 
Gives short notes on peach-leaf curl ( Taphrina deformans Tul.); plum taplirina; plum 
blight, apple blight (Bacillus amylovot us (Burrill) Trev.); pear leaf-blight ( Entomosporium 
macula,turn Lev.) ; black rot (Lcestadia bidwellii (Ell.) V. and R.); vine blight; brown rot of 
the peach ( Monilia fruc(igena) ; peach yellows and peach rosette. (J.F.J.)

ton, Mar. 10, 1892, pp. 88-95. 
Consists of notes on the following diseases: Peach curl, peach mildew, black spot of 
peaches, frosty mildew of peaches, peach rust, peach rot, peach yellows, clubbed branches 
of peach, stem and root tumors, peach rosette, pear diseases, and sycamore blight. (J. F. J.) 
760. Smith, Erwin F. Peach blight. <\Jour. Mycol., vol. vii, Washington, Sept. 10, 
1891, pp. 36-39, pi. v, vi. 
Describes appearance of disease and its manner of working on the tissues of plant. Pene¬ 
trates the blossoms and then spreads to twigs. Gives results of experiments to secure fruit¬ 
ing specimens of the fungus (Monilia fructigena), and describes its effect upon the woody- tis¬ 
sues. (J.F.J.)

Washington, April 30, 1891, pp. 164-173, pi. 1 (xv). 
Gives general outline of history of the fungus (Gloeosporium fructigenum Berkl.) which is 
the same as that producing hitter rot in apples. The external characters and microscopic 
characters are fully described. Under “treatment” gives the results of an experiment, 
showing that spraying with potassium sulphide and ammoniacal copper carbonate produced 
good results with apples. The same treatments would probably also protect grapes. (J. F. J.)

A general account of black rot of the grape, based for the most part on papers by American 
authors. (B. T. G.)

Washington, Sept. 10, 1891, pp. 27-36. 
Gives notes on orange diseases, with mention of causes, distribution, and remedies. The 
diseases treated are die-back, foot-rot. (Mai di-Goma), blight, scab, leaf-spot, soot.y-mold, and 
leaf-glaze. The last is due to growth of a lichen. (J. F. J.)

IV.— DISEASES OF FOREST AND SHADE TREES. 
764. [Anon]. Dr. Mayr on the parasitic fungi of North American forest trees. <Gard. 
and Forest, vol. v, N. Y., Jan. 27, 1892, pp. 37-38. 
Refers to examination of original specimens of Dr. Mayr, and gives as conclusions that 
Bhytisma punctiforme Mayr is It. punctatum Fries. Microsphceria corni Mayr is M. pulchra 
Cke. and l’k. Lophodermium infectans Mayr and Hysteriopsis acicola are considered too im¬ 
perfect to say more than that they belong to the order of Hysteriacepe. No good reason exists 
for the genus Hysteriopsis Mayr. Examination of Pucciiiidia abietis Mayr shows that ivhat 
is called the uredospore is not a JJredo , but a species of Tuberculin a, which infects Urcdinece. 
Uncertainty exists as to whether the species is T. persicina or a closely allied species. A 
second parasite attacking the Tuberculina is stated to be what Mayr considered the teleuto- 
spores of the iEcidium, whose form is too indefinite to determine. (J. F. J.)

folge, 7 Bd. Danzig, 1891, pp. 22-25. 
Mentions collection of Melampsora goe-ppertiana on Vaccinium vitisida’a (“Preiselbeer”). 
Near Ilmenau, Thiiringen finds Selerotinia baccarum causing a disease of berries of Vac¬ 
cinium; / eziza willkommii, causing canker of the larch; Lophodermium brachysporum, 
causing the falling of pine leaves. A few other species of fungi are commented on. (W. T. S.)
