A detailed description is published * * * § of the injury caused in various 
Leguminosse —Trifolium pratense, T. incarnatum , Medicago lupulina , and 
others — by the attacks of the clover-fungus, Sclerotinin Trifoliorum. The 
injury is chiefly produced by sclerotes in the leaf or stem which 
frequently fall to the ground ; but there is also a saprophytic conidial 
or Botrytis form in which infection may be conveyed to other host- 
plants. 
M. F. Debray f distinguishes between the anthracnose maculee and the 
anthracnose ponctuee of the vine. The former is due to the attacks of 
Sphaceloma ampelinum , the latter to those of Pseudocommis Vitis, the 
latter distinguished by its cancer-like appearance. 
Herr H. Klebalm j gives the results of a series of experiments on the 
cultivation of the species of Puccinia parasitic on species of Carex, the 
tecidioforms of which are found on species of Bibes. 
M. M. Molliard § describes the proliferation of the flowers of Bromus 
erectus caused by Ustilago bromivora ; the action of U. longissima on the 
structure of the vascular bundles of Glyceria aquatica ; and the 
anatomical modifications produced in a species of Symplocos by 
Exobasidium Symploci. 
Prof. B. D. Halsted || describes the mildew of the lime-bean due to 
the attacks of Phytophthora Phaseoli. On plants of asparagus he finds 
disease! tufts similar to the witch-broom of cedar and cherry trees, 
apparently caused indirectly by the asparagus rust, Puccinia Asparagi. 
Black specks on the leaves of roses were the result of Pilobolus crystallinus 
derived from the manure by which the bed was covered. 
Although almost uniformly free from the attacks of any similar para- 
site in Europe, the lilac is, in N. America, infested by a species of 
Erysipheae, generally described as Microsphsera Friesii. Herr P. Magnus^ 
has studied this fungus, and has found it very nearly allied to or 
identical with M. Alni and M. Betulse. It has probably infected the 
lilac in America from Ilex decidua , Betula lutea, or Corylus americana. 
The only allied species known on the lilac in Europe is Microsphsera 
Ehrenbergii, which has probably reached it from Lonicera tatarica. 
Parasites of the Vine.** — Mr. D. M‘ Alpine and Mr. G. H. Robinson 
give a detailed account of the Fungi which attack the vine in Australia. 
A complete list comprises 48 species — 28 parasites and 15 saprophytes. 
Of these 24 (15 parasites, 9 saprophytes) have not been previously noted, 
and their structure and life-history are described in detail. The disease 
known as brunissure is ascribed to climatal conditions, not to the attacks 
of Plasmodiophora Vitis. 
Fungus Parasitic on Zygnema.j't — M. E. de Wildeman describes a 
fungus endophytic in Zygnema cruciatum, causing great enlargement of
