Si SUMMARY OF CURRENT RESEARCHES RELATING TO 
penetrating odour of musk. This particular Mycomycete, with tetra- 
partite crescent spores, found on the mucous flux of limes and beeches, 
possibly also of other trees, is identified as being the Fusifiporium 
moschatum Ivitasato, and is therefore the same organism as the Fusarium 
aqueductum Lagerh. 
Black-rot of America.* * * § — M. P. Yiala describes in detail the deve- 
lopment of this disease of the vine, and discusses the various modes of 
treatment proposed. He states that its correct name is Lsestadia Bidwellii 
Viol, et Bav. 
Sig. U. Martelli f describes the spread of this disease in the vineyards 
of Italy. 
New Egg-plant disease, if— Under the name Plioma Solani sp. n., 
Prof. B. D. Halsted describes a fungus causing a new disease, which 
is very destructive to egg-plants ( Solarium esculentum) while still 
growing in the hot-bed, and causing the condition known as damping- 
os’. 
New Parasitic Fungus on Wheats — Herr G. Lopriore describes the 
destruction caused in wheat-grains and in seedlings by the attacks of 
Dematium pullulans. It has not previously been observed as a patho- 
genic parasite on wheat, and the author believes it to be the cause of 
various hitherto unexplained diseases. 
Pachyma.|| — After giving a full account of the structure known 
under this name, M. E. Fischer states that he agrees with M. Prillieux 
in his view of its nature, and concludes by stating that Pachyma ought 
to be considered as the sclerote of a hymenomycetous fungus. 
New Genera of Fungi.l — Mr. G. Massee describes two new genera of 
Fungi : — Sarcomyces, nearly allied to Hsematomyxa, but distinguished by 
a flat sharply margined hymenium, and by the muriform spores arranged 
in a single row in the cylindrical ascus ; and Dacryopsis, in which he 
places several species separated from Tremella, Coryne, and Ditiola. 
Actinomyces.** — Dr. C. E. Barnard gives details of the prevalence of 
actinomycosis in cattle in Tasmania and in the other Australian colonies, 
and of the transmissibility of the parasitic fungus which causes the 
disease, Actinoviyces, from the lower animals to the human subject. 
Lowly-organized Fungi.jt — M. E. de Wildeman describes the de- 
formation produced in filaments of Zygogonium by the attacks of Micro - 
myces Zygogonii, which he regards as allied to Synchytrium. He also 
describes a Chromatium allied to C. Weissii, and gives the reactions of 
the colouring matter with a variety of reagents.
