SUMMARY OF CURRENT RESEARCHES RELATING TO 
Indian Rusts and Mildews.* — According to Dr. A. Barclay, the 
most prevalent form of rust on wheat, barley, and oats in India, is not 
Puccinia graminis , but P. rubigo-vera ; the eecidio-form appears to occur 
on Berberis Lycium. The following rusts occurring in India are also 
described: — Puccinia Sorglii on Sorghum vulgare , Melampsora Lini on 
flax, Uromyces Pisi on Cicer arietinum and on Lathyrus sativus, Puccinia 
Fagopyri on buckwheat. 
Puccinia digraphidis.f — By culture experiments, Mr. H. T. Soppitt 
has proved that the aecidium of Convallaria majalis known as AEcidium 
Convallarise is a heteroecious Uredine, and that the host which bears the 
uredo- and teleuto-spores is Phalaris arundinacea. For the uredospore 
generation he proposes the name Puccinia digraphidis. 
NewRamularia on Cotton4 — Under the name Pamularia areola , 
Prof. G. F. Atkinson describes a new parasitic fungus forming brown 
spots on the under side of the leaves of the cotton-plant in Alabama. 
Uredo notabilis.§ — Among other new fungi from Australia, Herr 
F. Ludwig describes this remarkable species of Uredo , parasitic on the 
phyllodes of Acacia notabilis. It causes conspicuous inflated bladders, 
as much as three cm. in diameter; the epispore of the uredospores is 
distinguished by its remarkable reticulate sculpture, so that they might 
readily be taken for teleutospores. 
A beautiful new Clathrus, C. ( Ileodictyon ) Tepperianus , is also 
described from South Australia. 
iEcidium Schweinfurthii.|j — Under this name Herr P. Hennings 
describes a remarkable new species of parasitic fungus which causes 
large galls on the ovary or young fruit of Acacia fistula in Central 
Africa. 
New Type of Dermatomycosis.1T — M. R. Blanchard describes a 
disease in the skin of a green lizard, in the form of tumours produced by 
a mucedineous fungus belonging to the genus Fusarium or Selenosporium. 
The tumours are permeated throughout by septated conids springing 
from mycelial filaments of two kinds, acrogenous, and springing laterally 
from the mycele. The author regards this as an example of a fungus 
ordinarily saprophytic, which becomes parasitic under exceptional con- 
ditions. 
Phalloideae.** — Dr. E. Fischer gives a complete account of the history 
of development of the Phalloideas, which begins with the broadening 
of the end of a hyphal bundle, in which the central bundle and the 
volva-jelly are formed as denser portions of the tissue, while between 
these there remains an intermediate tissue which is not at once differen- 
tiated. The first differentiations of this intermediate tissue bring about 
the variations in the form and structure of the receptacle, and of the 
distribution of the glebe, which afford specific characters. From this
