tion of the British TJred'mece on the continental method by Plowright, 

 and a paper on the general classification and nomenclature of the order 

 by Cooke. The fungi of the Netherlands are treated by Oudemans in 

 his revision of the Perisporiacece of that country, and by Calkoens in bis 

 synopsis of the Uredinece and Ustilaginece of Holland. French species 

 have been described in several articles in the Revue Mycologique, and 

 by Fabre in the Ann. Sci. Nat. in a continuation of his Sphceriacece of 

 Vaucluse, and illustrations of French species are given in the continua- 

 tion of Gillet's Hym&nomycetes de France and Patouillard's Tabulcc-Ana- 

 lyticce. Australian fungi have been enumerated and described by Cooke 

 in Grevillea. The fungi of Rabenhorst's Kryptogamen Flora have been 

 continued this year through the Basidiomycetes, and two centuries of 

 Winters Fungi Europcci have appeared. Erikssen's Fungi Scandina- 

 vici has been continued by a second century, and a new series of fungi 

 exsiceati, Ungarns Pilze or Hungarian fungi, has been started by Liu- 

 bart. 



Numerous papers have appeared on fungi which produce diseases of 

 plants, more especially those of the grapevine. The Untersuchungen 

 aus demforstbotanischen Institut of Munich, edited by Prof. Robert Har- 

 tig, has several important papers. Dr. Heiurich Mayr gives an account 

 of the disease caused by Nectria cinnaoarina in maple, linden, and horse- 

 chestnut. Hartig describes the diseases of the white pine (Pinus 

 strobus) which appears to be much more susceptible to fungous dis- 

 eases in Germauy than with us. Hartig also gives a very full account 

 with illustrations, of what he calls Rhizomorpha necatrix, which pro- 

 duces the rot of the root and lower part of the stem of grapes, a dis- 

 ease which had been previously attributed to a number of different 

 fungi by French and Italian writers. No perithecia were found by 

 Hartig, who asserts that tbe Rhizomorpha is quite different from tbat 

 which has been connected with Agaricus melleus. 



Tbe elaborate memoir of Cornu, Le Peronospora des vignes, which 

 forms one of the series of papers on tbe diseases of the vine, published 

 by order of the French Academy, although printed in 1882, was not 

 widely distributed until the present year. The writer gives a very full 

 account of the literature of the subject and details of the microscopic 

 structure with numerous excellent plates. Pnllieux, in the Bull. Bot. 

 Soc, reports that the oospores of Peronospora viticola have been made to 

 germinate. In germination the oospores give out a tube instead of 

 zoospores, which is contrary to what take place in the case of tbe con- 

 idia. The Bericht. Deutsch Bot. Gesell. contains a paper by Frank, on 

 some new and little-known diseases of plants, in which he describes a 

 fungus, Fusicladium tremulce, which attacks Populus tremula, and he re- 

 fers also to Gloeosporium Lindemuthianum, which produces discolored 

 spots on the pods of cultivated beans, and has prevailed not only in 

 Europe but also in this country during the year. The Gardener's Chron- 

 icle has several notices of fungous diseases, a considerable space being
