ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 395 



Fungi from Greenland.* — C. Ferdinandsen gives a list of the larger 

 terrestrial fungi brought back by the Denmark Expedition from that 

 territory. There were twenty species ; one new Gasteromycete is de- 

 scribed, Galvatia arclica. 



J. Lind f describes the Micromycetes from the same country, 

 chiefly parasites on the Phanerogams collected. He lists sixty-live 

 species, of which four are new to science. Notes are given on the 

 microscopic characters of many of the species. 



Fungi from Venezuela and the West Indies.f — 0. Ferdinandsen 

 and 0. Winge describe the fungi collected on Warming's Expedition. 

 There are thirty-six species listed with critical notes. Two new genera 

 are described, Myxotheca of uncertain position, but evidently near to 

 Plectascinese, and Stilbochalara (Phasostilbeae). The authors describe 

 four new species. 



Notes on Chilian Fungi. I.§ — Roland Thaxter spent six weeks at 

 Punta Arenas on the Straits of Magellan, and gives notes of the fungi 

 observed by him during the summer. A great forest of the antarctic 

 beech {Nothofagus) had been burned down in the district near the town, 

 but in the woods some distance away quite a large fungus-flora was 

 found, Agaricaceas, Hymenogastreas, Pezizas, and Myxomycetes all 

 flourishing and maturing in the valleys where the temperature seldom 

 rises above 60° F., while freezing temperatures are common at night all 

 through the short summer. The more resistant forms, such as the 

 Pyrenomycetes, were well represented, though Polyporei were scarce. 



Two new species of parasitic microfungi are described, Taphrina 

 entomospora and Uncinula Nothofagi, both on leaves of Nothofagus. 



German Fungus-flora. || — W. Herter is the author of the latest 

 fascicle of this work. It treats of the Autobasidiomycetes, in which are 

 included all Hymenomycetes and Gasteromycetes. Herter gives a 

 general account of the history of these groups since their earliest 

 mention by Greek writers up to the most recent works of systematists. 

 He gives also an account of their development and of the different 

 forms assumed by mycelial growth, fruit-bodies, etc. Notes are also 

 given on their habitat and economic uses. The separate orders and 

 families are then dealt with down to Trpex, one of the Hynieno- 

 mycetineee. 



Physical Conditions of Resistance of the Vine against Mildew. % 

 Jules Laurent finds that the power of resistance in leaves and grapes 

 depends on the molecular concentration in the cells of the host-plant. 

 He explains his methods of work, and gives tables of the results obtained. 

 A series of experiments was also carried out on potatoes as to their 

 resistance to Phytophthora infestans, and the results obtained were 

 exactly parallel to those observed in the vine.
