ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 81 



Smuts of Australia.* — These have been described by D. Mc Alpine 

 in a companion volume to his " Uredineae," published some years ago. 

 He includes ten genera already established, but he finds thirteen new 

 species. Entyloma Mel Hot i sp.n. is the first of that genus detected on 

 a leguminous plant. The author describes the conditions that favour 

 the growth of the fungi, the life-histories of the organisms, their vege- 

 tative and reproductive organs, etc. He also touches on the questions 

 of parasitism and immunity, and gives special attention to the smuts of 

 cereals. 



German Cortinarii.f — F. Kaufmann has published a systematic 

 account of the two subgenera Phlegmacium and Znoloma. He gives 

 keys to the species, which take into account all the points that help in 

 determination, especially the colours of the pileus and the gills. The 

 author inclines to refer nomenclature back to Linnaeus rather than to 

 Fries. The selection of Fries's Systema as the starting point shuts out 

 mvcolosnsts who have an undoubted risjht to be considered, and confuses 

 the often interesting history of many species. 



Monograph of Hygrophorus.J — F. Bataille's account of this genus 

 includes descriptions of eighty-two species. He retains Fries's sub- 

 divisions of the genus, and does not consider the number of spores on 

 the basidium as a generic character. He provides a key to the species, 

 using all characters easy to be recognized. 



Notes on the Larger Fungi.§ — Rene Maire published some time ago 

 the result of his employment of reagents as aids to the determination of 

 species in Russula. Potron has worked on the same lines, and publishes 

 a short paper explaining his methods of using the reagents, and the 

 success that attended their application. Usually he found that boiling 

 a small portion of the pileus in water was sufficient to obtain a coloured 

 fluid, which varied for the different species. He gives the colour- 

 reactions for eight species of Russula. 



C. Torrend || records finding a variety of Trametes ochroleuca in 

 Portugal, a fungus previously found only in the tropics. Torrend calls 

 attention to the remarkable fact that several fungi supposed to be con- 

 fined to the tropics have been found in Portugal. 



Punctularia tuberculosa. % — C. Torrend found this tropical member 

 of the Thelephorere on an oak-tree in Portugal. It is of a beautiful 

 violet-red colour, and spreads widely, though in Portugal it has not been 

 observed to form spores. There was also found beside it a form of 

 Ceriomyces, with many filaments and red-violet spores. Torrend finds 

 the Thelephora to be identical with Retirularia venulosa B. & C. The
