F. von Thumen describes (Verhandl. der k, k. Zool.-bot. Ges. 

 in Wien, xxix., p. 523-524) two new leaf-inhabiting Ascomycetes 

 (found within the range of the Flora of Vienna) ; one is a new 

 species of Ascomyees (A. alutaceus) which grow on the leaves of 

 Quercus msedanu, Vukot, at Kamrnerstein. The other is a new 

 species of Sphmrotheca (S. Xieslii), the perithecia of which appear 

 singly (i.e., never in clusters) but numerously on the leaves of 

 Sorbus aria in the park of the Jesuits' College at Kalksburg and at 

 Leopoldsberg.

Part I. — SHfsvampar [Hymenomycetes.] By P. A. Karsten. 



This first part contains the Agaricini of Kussia, Finland, and 

 Scandinavia. The author recognises eighty genera of Agaricini, 

 which are composed chiefly of a part of Fries' subgenera of 

 Agariem elevated into genera, and of several other genera new or 

 described elsewhere. Notably among them are : — Amanitopsis, 

 Eoz., Cortinellus, Roz., Panellm, Karst., Scytinotus, Karst., Lepto- 

 glossum, Karst., Leptotus, Karst., Lentinellus, Karst., Hemicybe, 

 Karst., Hozites, Karst., Gymnopilus, Karst., Gymnocybe, Karst., 

 Phialocybe, Karst., Symocybe, Karst., Galerula, Karst., Roiunegueria, 

 Karst., Ryartites, Karst., Namatoloma, Karst., Pannucia, Karst., 

 Deconica, W. G. Sm., Anellaria, Karst., Chalymmota, Karst., 

 Onochopus, Karst., Psellioptora, Karst., and Coprinellus, Karst. 

 Some good might have been done if this energy in adding new 

 genera to the confusion in the Agaricini had been directed to 

 "sinking" the numerous species of that group established on 

 frivolous grounds. G. M. 



Dr. Lange has issued the fiftieth fascicle of the ' Flora Danica.' 

 It contains figures and descriptions of the following new species : 



Calamagrostis hyperborea, Potentilla Ranunculus, P. Friesiana, and 

 ( arex TJrejeriana — all of Lange. 



The indefatigable Baron F. von Mueller has issued an ■ Index 

 Perfectus ad Caroli Linnsei Species Plantarum/ which is worthy of 

 its name, and is both interesting and useful.
