takes place between them by the coalescence of their contents after 

 resorption of the septum ; the apices of the protuberances, however, 

 remain, and are shut otf as small cells. The spherically swollen cell 

 then becomes separated as a zygospore, excretes a thick stratified cell- 

 wall, which becomes brown and covered with conspicuous warts, and 

 which always possesses the characteristic beak. The direct produc- 

 tion of zygospores from conidia was also observed, without the 

 intervention of a mycelium. 



New Genera of Fungi.*— Among a number of new species of 

 fungus from the province of Venice, Sig. G. Bizzozero describes the 

 following new genera : — 



Testudina (Perisporiaccce). Perithecia sparsa v. sjepius dense 

 gregaria, superficialia, carbonacea, astoma, globosa v. pyriformia, 

 dein in areolas subpeutagonas regulariter ruj)ta, basi subnuda. Asci 

 globosi-clavati, stipite articulate, longo, subinde ramoso iuserti. 

 Sporidia ellipsoidea, 1-septata, fu.iginea, asperula. On decaying 

 yew-leaves. 



Cytoplea (Sphteropsidefe). Stroma subsuperficiale, pulvinatum, 

 confluendo effuso-crustaceum, intus monostiche multi-locellatum ; 

 loculis plus V. minus distincte cuboideis. Sporulse ovoideo-oblongas, 

 continua3, olivaceo-fuliginese, initio subcatenulatae, stipitatae et fili- 

 f ormi-paraphy satse . 



Dacnjmycella (Hyphomycetes ?). Acervuli discoidei, rubro-rosei, 

 superficiales, subinde confluentes, initio subgelatinosi, sicci duriusculi, 

 nitidi. Basidia distincte et longe ramosa, filiformia, ubique, basi 

 excepta, verruculoso-conidifera. Conidia subrotunda, hyalina. 



New Genera of Fungi.f — In the second series of Sigg. P. A. 

 Saccardo and A. N. Berlese's ' Miscellanea Mycologica,' a large 

 number of new species are described, together with the following 

 new genera : — Among Australian fungi, chiefly collected by Scorte- 

 chini in South Queensland: — Scortecliinia, belonging to Sphaeriacefe, 

 with the single species S. acanthostroma, on the bark of trees ; GibelUa, 

 intermediate between Butryosphseria and Cryptosporella, on decorti- 

 cated twigs ; Gamospora, belonging to Sj^hasropsideaB, a peculiar genus, 

 in which the stylospores are formed, as in Basidiomycetes, in twos or 

 threes on the apices of basidia ; a single species, 0. eriosporoides, on 

 unknown coriaceous leaves. Among North American fungi, from 

 various collectors : — Martindalia, a genus of Hyphomycetes, with one 

 species M. spironema, on an elm-wood vessel in a cellar ; PericonieUa, 

 also belonging to the Hyphomycetes, parasitic on living leaves, 

 already described by Winter as a species of Periconia ; Scoriomyces, 

 a very remarkable genus of quite uncertain position ; the only species, 

 S. Crcujini, on the bark of MJms venenata. Among Italian fungi from 

 the province of Padua: — Uncigera, belonging to Hyphomycetes, the 

 single species, U. Cordae {Fusisporium uncigerum Corda) on elm-leaves.
