trophied, and from the swelling spine-like processes grow out. Other 

 processes grow out later, and are white with the mycelium of the fungus. 

 Large basidiospores are formed and are very abundant. A. L. S. 



Common Mushrooms of the United States. — Louis C. C. Krieger 

 {National Geographic Magazine, 1920, 37, 387-439, 16 pis. and figs.). 

 The author gives a popular account of the more common edible and 

 poisonous species, illustrated by a beautiful series of photographs and 

 coloured drawings. The species described are mostly abundant in 

 Europe as well as in America. A. L. S. 



Light-coloured Resupinate Polypores. III. — W. A. Murrill 

 {Mycologia, 1921, 13, 83-100). The white species of Poria have 

 already been described by the author ; the present list deals with those 

 coloured lilac, red, purple, etc. — twenty-six species. A number of them 

 are new to science. A. L. S. 



Genus Tinctoporia.— W. A. Murrill {Mycologia, 1921, 13, 122-8). 

 The author describes three species belonging to this genus of Polypores. 

 Two of these, American species, Timtoporia alhocincta and T. graphica, 

 stain the substratum ; the third, T. fuligo, does not leave any stain ; it 

 was originally described from Ceylon. A. L. S. 



Mycological Notes.— C. G. Lloyd {Cincinnati, Ohio, 1920, N. 64, 

 985-1029, 16 pis.). .Lloyd gives portraits and short accounts of some 

 eminent mycologists — George, W. Clinton, Paul Hariot, Rev. L. J. 

 Grelet and Worthington G. Smith. The fungological notes range over 

 a wide field, being based on material sent to him from all countries. 

 Gasteromycetes, Hymenomycetes and Ascomycetes all come under 

 review, and the rarer specimens are figured and described. Among those 

 described are many Polyporese^hick were sent to him from Cuba, Africa, 

 Singapore, Australia, etc. Among other unusual forms he notes two 

 species of Ptyciiogaster, one from West Africa, the other from Japan.

Two Species of Fuscoporia. — W. A. Murrill {Mycologia, 1921, 

 13, 119). Both of the Polypores described are American species, and 

 were originally placed in Polyporus. A. L. S. 



Fermentation Organisms of California Grapes. — W. Y." Cruess 

 {Univ. Calif. Publications Agric. ScL, 1918, 4, 1-66, 2 pis., 15 figs.). 

 The author classifies the organisms found on grapes as — (1) budding 

 fungi, including moulds, true yeasts which form spores, and pseudo-yeasts 

 which do not form spores ; (2) fission fungi, including bacteria (non- 

 motile rods), bacilli (motile rods), the various forms of Coccaceaj, and 

 the fission yeasts. AH of these, except bacilli, Coccaceas and fission 

 yeasts, were found in California grapes. The various moulds, yeasts, 

 bacteria, etc., are described, tiie types are figured, and the species 

 enumerated with notes. Nineteen organisms in all have been studied, 

 the majority of them harmful in wine-making. The yeasts found on the 

 grapes should not be relied on for fermentation ; some of the grapes 

 contained no true wine-yeasts. Moulds occur mostly on the surface,
