SUMMARY OF CURRENT RESEARCHES RELATING TO 
fungi belonging to tbe genera Cordyceps, Isaria, and Sporotrichum. A 
copious bibliography is appended. 
Parasitic Fungi. — Herr P. Hennings * describes a very large number 
of new species of parasitic and saprophytic fungi from Goyaz, in Brazil, 
belonging to the genera Ustilago , Uromyces, Puccinia, Cronartium , 
Bavenelia, Uredo, JEcidium, Asterina , Asterula , Asteronia, Dimerospo- 
rium, Parodiella, Mcliola, Hypocrella, Ophioceras. Tr abulia , Xylaria , 
Phylla chora, Dothidella , and Tryblidium. 
MM. E. Prillieux and G. Delacroix f find that a prevalent disease 
of the sugar-cane in Mauritius is due to the attacks of Coniothyrium 
melasporum. 
Herr F. Schwarz J describes the extensive injuries caused in fir 
plantations by the attacks of Cenangium Abietis. It produces two kinds 
of pycnid, one with unicellular, the other with pluricellular conids. 
Herr B. Frank § describes the injuries iuflicted on the cultivated 
beet by the attacks of Phoma Betoe. The fungus is both parasitic and 
saprophytic, but dryness is indispensable to its develojnnent ; in fresh 
green leaves and stems it can only penetrate injured spots. The spores 
germinate in the soil ; as many as 160,000 may be contained in a single 
pycnid. 
Herr F. Kruger |] gives details of the mode in which the parasitic 
fungus Septoria graminum attacks and destroys wheat-crops. 
Prof. G. F. Atkinson 1 gives the life-history of those fungi which 
are the most active in producing the phenomena of damping off, viz. 
Artotrogus debaryanus on seedlings ; A. intermedins and Completoria 
complens on fern-prothallia ; Volutella leucotricha sp. n. on cuttings; 
together with some sterile and undetermined forms. 
Prof. R. Hartig ** describes a disease which is very destructive to 
the leaves of the larch, caused by a hitherto undescribed parasitic 
fungus, Sphserella laricina sp. n. 
From an examination of the uredospores of Uredo Aspidiotus Peck 
parasitic on Pliegopteris Dryopteris , Herr P. Magnus now concludes 
that it must be removed from this genus and placed under Melam- 
psorella. 
Fungus-diseases of Cultivated Crops. Jij:— The most recently pub- 
lished parts, completing the first volume of this beautifully illustrated 
work by Dr. P. Yoglino, contain descriptions of the structure and life- 
history, and instructions as to the best mode of combating the attacks 
of the following parasitic fungi ; each part having a coloured plate : —
