230. -. Beet Rust (with fig. from Ann. Rep., 1887, U. S. Dept, of Agr.). Ibid., p. 
201. Mentions presence of disease as confined, so far as known, to California. 
Gives life-history, and suggests as remedies iron chloride in dilute solution. 
231. -. Powdery mildew of the cherry (with figs.). Orchard and Garden, Little 
Silver, New Jersey, December, 1890, Vol. xii, No. 12, pp. 210-211. Describes 
popularly the life-history of Podosphcera oxyacanthoe, recommending as pre¬ 
ventive fungicide, sulphuret of potassium, one-half ounce to the gallon of 
water, applied while warm. 
232. -. Treatment of anthracnose of the vine. Ibid, (quarter column). Quotes 
formula for treatment from Le Prog. Agricole, October 26, 1890: Water, 3 
gallons; iron sulphate, 7 pounds; copper sulphate, 2 pounds; sulphuric 
acid, 1 gill. Also, powder made by mixing equal parts of Portland cement 
and sublimated sulphur. 
233. -. Rose leaf-blight. Ibid, (with figs.). Gives popular description of Ccrco- 
spora roscecola and effects upon host. Thinks plants placed where air and 
light are abundant seldom suffer from the disease. 
234. -. Beet leaf-blight (with figs.). Ibid. Describes Cercospora beticola popu¬ 
larly, and recommends clear and open culture as means of lessening liab ; lity 
to disease. 
235. Seymour, A. B. Rose rusts (with figs.). American Garden, New York, Oc¬ 
tober, 1890, Vol. xi, No. 10, p. 609. Notices Phragmidium mucronatum and 
Ph.rosce-alpince, giving distinctions and life-history. Decides Pli. mucrona¬ 
tum, var. America num , Pk., to be identical with Ph. rosce-alpince. 
236. Stewart, Henry. Cotton rust. American Agriculturist, New York, December, 
1890, Vol. xlix, No. 12, p. 638 (1 column). Denies popular belief that the 
disease is in any way connected with the growing of clover, and refers it to

scope, January, 1891, Vol. xi, No. i, pp. 24-26. Gives an account of a new 
genus of fungi ( Sepiocarpus) described by Kopf in a monograph, as infecting 
diatoms in subalpiue bog-pools of Norway, and translated by Mr. G. C. Karop 
in Journal of the Quakett Microscopical Club, London. The species of diatom 
affected was Pinnularia, and the fungus is considered distinct from that at¬ 
tacking Desmids. 
238. Tiiaxter, Roland. The potato scab. Bull. No. 105, Conn. Agrl. Ex. Sta., New 
Haven, December, 1890, pp. 3,4. Gives preliminary report upon the disease 
which has been proved beyond doubt to be connected, as an effect, with an ex¬ 
tremely minute fungus resembling, with exception of a branching character, 
certain polymorphic bacteria. Records careful inoculation experiments which 
establish connection between the “ deep ” scab and the fungus, and gives short 
account of pure cultures in solid culture media. Mentions work in progress 
upon morphologically identical fungus found commonly upon refuse material. 
239-. On certain new and peculiar North American Hyphomycetes, I. (with Plates in 
and iv), Bot. Gaz., Jan. 15, 1891, pp. 14, 26. Enumerates with valuable notes 
the American species of the genera CEdocephalum , Preuss, as CE. glomerulosum 
Bull.) Sacc., CE. echinulatum, n. s., CE. verticillatum n. s., CE. pallidum (B.and 
Br.) Cost. Considering CE. elegans, Preuss, as distinct from CE. glomerulosum 
and CE. roseum , Cook, as a synonym. Decides Bhopalomyces pallidas, B. and 
Br. and It. candidus, B. and Br. to be identical and synonyms of CE. pallidum; 
and Haplotrichum Jimetarium , Riess., as also a synonym of the same species. 
Gives Ithopalomyces elegans, Corda, R. cucurbitarum, Berk. & Raw, It. strangu- 
latus, n. s., as known American members of the genus, and descibes a new 
genus, Sigmoideomyces, upon the species S. dispiroides, found upon under side 
of a moist log, Burbank, east Tennessee. Notes that the genus bears much 
the same relation to CEdocephalum that Dispira does to Aspergillus. Closes 
with synopsis of the described species of CEdocephalum and Bhopalomyces.
