Zygosaccharomyces pastori : New Species of Yeasts with Hetero- 

 gamic Copulation.— A. Guillieemond {Bull.Soc. MycoL France, 1920, 

 36, 20;)-ll, 3 pis., 1 fig.). The new yeasts occurred in a mucilaginous 

 exudation from a chestnut tree near to Lyons. The cultivation of the 

 yeast in all its stages is described. The ascospores resemble those of 

 the genus Willia. A. L. S. 



New Thermophile Stocks of Asperg-illus glaucus. — Paul 

 YuiLLEMiN {Bull. Soc. Mycol. France, 1920, 36, 127-36, 3 figs.). The 

 writer recalls the work on this fungus of Louis Mangin, who had 

 isolated twenty-three different stocks, all of which formed perithecia. 

 Mangin designated fourteen of these stocks as Eurolium herhariorum, 

 seven as E. repens, with two new species E. amstelodami and E. Gheva- 

 lieri, the latter having been lirought from Chari-Tchad on the equator. 

 Vuillemin has taken up the study of four thermophile stocks isolated 

 from parasitic maladies of man in Europe. One of them belongs to 

 Enrotiam repens, the other three approach E. amstelodami. He gives 

 an account of his cultures of these fungi, their morphology and the 

 thermal conditions that affect their development. He discusses the 

 affinities of the various stocks. A. L. S. 



Effect of Salt Proportions and Concentration on the Growth of 

 Aspergillus niger. — C. M. Haenseler {Amer. Jovrn. Bot., 1921, 8, 

 147-63, 6 figs.). The fungus was grown on three different salt solu- 

 tions. Details of methods and results are given. Yield in dry weight 

 of the fungus was approximately proportional to the amount of NO3 

 present in the culture ; with varying sugar concentrations, the dry 

 weights of the fungus were very nearly proportional to the sugar con- 

 centrations of the culture-media. A. L. S. 



Aspergillus flavus, A. Oryzae, and Associated Species. — Charles 

 Thorx and Margaret B. Church {Amer. Jouni. Bot., 1921, 8, 103- 

 26, 1 fig.). These species of Aspergillus are closely associated with the 

 fermentation of food products in the East, but are really cosmopolitan 

 fungi. The several species concerned in the fermentation process have 

 been carefully contrasted and described by the authors, who have culti- 

 vated most of them. A. L. S. 



Septosporium Ferrari sp. n. — Martino Savelli {Bull. Soc. Bot. 

 Ital, 1916, 6-7, 92-4, 4 figs.). The fungus grew on living leaves of 

 Ficusferrvginea, where it formed spots on the upper surface. A. L. S. 



Three Fungi Imperfecti. — Jessie S. Batliss Elliott and Helena 

 0. Chance {Trans. Brit. Mycol Soc, 1921, 7, 47-9, 1 fig.). The fungi 

 described were found on dead twigs of Finus sylvestris at Oxshott, 

 Surrey. The first is distinguished by the spores and has been named 

 Gijtotriplospora Pini g. et sp. n. The spores are at first oval, but on 

 maturing they become elongate and curve over so as to become obliquely 

 attached to the sporophore, which continues to adhere to the spore 

 somewhat like a cilium. Another fungus, Kaemospora Strobi Allescher,
