anomalus resemble those of Endomyces decipiens , but are distinguished 
therefrom by being smaller and by budding like S. cerevisise i. 
The author’s article ends by criticizing the attempts which have 
been made during the past thirty years to show that the Saccharomycetes 
are not independent species, but developmental forms of higher 
fungi, and he points out that the confusion has chiefly arisen from not 
properly distinguishing the true Saccharomycetes (yeasts with endo- 
genous spore-formation) from the various Blastomycetes devoid of such 
spore-formation. 
Researches on Uredinese.* * * § — Herr P. Dietel epitomizes the most 
important additions to our knowledge of this order of Fungi acquired 
during the last ten years. 
Uromyces Cunninghamianus sp. n.j — The late Dr. A. Barclay 
describes, under this name, a remarkable fungus parasitic on Jasminum 
grandiflorum at Simla. Its peculiarities are mainly three, viz. the 
production of teleutospores within the peridia ; the assumption of a 
distributive function by the aecidiospores ; and the very peculiar 
germination of the aecidiospores. The second of these peculiarities 
renders the production of uredospores unnecessary, and accordingly 
there are none. When the aecidiospore germinates, the germ-tube, 
which is quickly emitted, soon acquires the appearance of a promycele, 
as in the case of EndopJiyllum , suggesting an affinity with that genus ; 
but it does not actually assume the character of one, as it never 
produces sporids. It produces, on the contrary, sterigmatous branches 
which directly enter the tissue of the host, and there form another 
mycele, commencing the life-cycle over again. 
Diorchidium.J — Herr P. Magnus points out that the position of the 
germ-pores and of the septum in the teleutospores of Diorcliidium 
presents no constant distinction from those in Puccinia, and that 
Diorcliidium leve must, therefore be sunk in the latter genus. To the 
true genus Diorcliidium he assigns all those species with two-celled 
teleutospores, in which the pedicel is inserted parallel to the septum, 
and the two cells are of similar form, with rounded poles, and with 
the germ-pores near to the poles. The type-species of the genus 
is D. Woodii , and to it must also be referred Puccinia lateripes and 
P. insueta. 
Parasite of the Cockchafer.§ — MM. E. Prillieux and Delacroix, 
recurring to this subject, point out that the two species of Botrytis , 
B. tenella and bassiana , differ in their spores, those of B. tenella being 
oval-oblong, while those of B. bassiana are globular, as also in certain 
special physiological properties. The authors conclude by giving 
details of the manner in which B. tenella can be multiplied, and also 
the mode in which insects can be infected with the parasite. Besides 
the cockchafer larva, the following insects have been infected by the 
authors with the spores of B. tenella , — Bhizotrogus solstitialis , Cetonia 
aurata , and the larvae of Liparis chrysorrhcea.
