of them afford a home for diseases caused by parasitic fungi. A number 

 of the common weeds are mentioned arranged in their natural orders 

 and descriptions, or references to descriptions cf the diseases to which 

 they are subject are given. 



Fungi Polonici.* — J. Bresadola publishes a continuation of the list 

 of fungi from Poland. He states the time of year when the specimens 

 were gathered, but he does not give particular localities. Under the 

 genus Kneiffia he places the species that have been classified as Penio- 

 phorce. He considers that Kneiffia as based on the type K. setigera is. 

 indistinguishable from the genus Peniophora, and that the character of 

 one-spored basiclia breaks down even in the type species, where the 

 basidia are frequently four-spored. He adds a number of new forms 

 to the genus. Many new species belonging to other genera are also 

 described, and a plate is published with figures of three new species, 

 EicKleriella incarnate, E. Uucophcm, and Platyglwa Miedzyrzecensis. A 

 few Mycetozoa are recorded and one new Schizomycete, Spirillum 

 roseum sp. n. 



American Fungi.j — W. A. Murrill continues his study of the Poly- 

 poraceas and deals in the present paper with the genus Fomes as under- 

 stood by Grillet. He gives a synopsis and description of eleven American 

 species ; two of these are new to science and other two are exclusively 

 American. To a note on Fomes Laricis, he records its appearance on 

 pine and spruce. In Europe its growth is confined to the larch. 



In another paper % he publishes a historical review of all the genera 

 of this group. 



The same author § proposes a new family of Basidiomycetes, Xylo- 

 phagacese, to include all gelatinous forms with a porose hymenium. 

 These are subdivided into three families, Favolaschieas (Favolasehia), 

 Xylophagea? (Xylophagus), and Glceoporete (Glmoporus). 



F. S. Earle || publishes a key to the North American species of 

 Stropharia. There are eleven species of the genus dealt with. 



The same author % furnishes a new key to the genus Lentinus. He 

 recognises the following sections : — Criniti, including Pulverulenti ; 

 Lepidei, Cochleati, Cornucopioides, Pleuroti, and Resupinati. The 

 species included in the two latter sections, he thinks belong more pro- 

 perly to the genera Pleurotus and Panus. 



C. G. Lloyd** continues his issue of mycological notes. He de- 

 scribes the genera and species of the BovistEe, Tylostomeas, and some 

 of the Poclaxineas with notes on other fungi. 



W. C. Blasdale ft writes on a rust of snapdragon. 

 A. P. Morgan %% describes a new species of Sirotheciwn. Elias J. 

 Durand gives the American species of Sarcosoma. J. B. Ellis and 

 W. A. Kellerman §§ describe two new species of Cercospora. W. A.
