 Sor.] Centralbl. Bakt. II Abt. 50: 335-356. PL 1 {colored). 1920.— The fungus growth is 

 pictured in colors. The results of a number of experiments in which various hosts were used 

 are recorded. An extensive bibliographj'- is appended. — H. M. Fitzpatrick, 



2057. GuiLLiERMOND, Alexandre. Theyeasts. Translated and revised in collaboration 

 with the original author by F. W. Tanner, xix + 4^4 P-, 163 fig. John Wiley and Sons, 

 Inc.: New York; Chapman and Hall, Ltd.: London, 1920. — This English edition is based on 

 Guilliermond's "Les Levures," published in 1912 as a volume of the Encyclopedie Scientifique. 

 It is not merely a translation, but constitutes a revision in the light of recent literature. The 

 yeasts are treated from the standpoints of morphology, cytology, physiology, phylogeny, and 

 taxonomy. Methods for use in the characterization and identification of species are given, 

 as well as methods of culture and isolation. In the taxonomic treatment the group is subdi- 

 vided into Saccharomycetes and Non-Saccharomycetes, the latter group embracing such genera 

 as Torula, Pseudosaccharotnyc.es, Crijptococcus, and Mycoderma. Fungi related to the yeasts 

 are also discussed, e.g., Endomyces albicans, Monilia Candida, Pseudomeliola albomarginata, 

 and Parendomyces pidmonalis. Many of the forms are figured. An extensive bibliography 

 is appended. A large number of pathogenic yeasts are described. An attempt has been 

 made to present in a single book the essential information available concerning the whole 

 group of yeasts and yeast-like organisms having in mind every point of view. Although 

 several treatises have previously appeared dealing with yeasts in relation to fermentation 

 this is the first book to cover the broader field, and it fills a need long felt for a comprehensive 

 reference work on this subject. — H. M. Fitzpatrick.

 of a case from which a new species was isolated. Jour. Infect. Diseases 28: 232-248. 1921. — 

 A new species of Actinomyces, A. gypsoides, which is acid fast and pathogenic is described. 

 It is characterized by strong proteolytic activities, the darkening of media containing peptone, 

 and the possession of chalky-white aerial mycelium. — Selman A. Waksman.

 Hedwigia 60: 331-341. 1919. — A key to the species of the genus Russula based primarily on 

 color and taste. Almost 100 species are included. — H. M. Fitzpatrick.

 ference to the presence and function of spermatia. Amer. Jour. Bot. 7: 435-444, ^ fig,. 1 pi. 

 1920. — Spermatia or similar structures have been observed in various families of ascomycetes. 

 As an example of a species which produces spermatia, the author outlines the life history 

 of Mycosphaerella Bolleana n. sp., an ascomycete parasitic on the leaves of the fig. He presents 

 a diagnosis of the species and describes in detail the production of conidia, spermatia, and 

 asci. All attempts to germinate the spermatia failed. Artificial infections with ascospores 

 produced conidia on the leaves of the fig. — E. W. Sinnott. 



2061. HoHNEL, Franz von. Mycologische Fragmente. [Mycological fragments.] Ann. 

 Mycol. 17: 114-133. 1919 [1920]. — Tricholoma tenuiceps Cooke & Massee is transferred to 

 Russula. Myocopron Pandani, on dry leaves of Pandanus sp., and Phrag^nothyrium fimhriatum, 

 on leaves of Ardisia fuliginosa, are described as new; the latter is compared with P.corruscans 

 (Rehm) Th. Meliola rubicola P. Henn. is considered identical with Sphaeria calostroma Desm. 

 The structure of the perithecial wall and appendages is described and the relationship of 

 this genus, as illustrated by this species, with other groups is discussed. Asterella olivacea 

 V. H. is transferred to Microthyriella v. H. and the relationship of the latter genus with 

 Schizothyrium discussed. P seudonectria Metzgeriae Ade. & v. H., found on upper surface of 

 thallus of Metzgeria furcata, is described as new. Sphaeria bryophila Roberge is thought to 

 be identical with S. muscivora Berk. & Br. and the new combination Nectria muscivora (Berk.
