" The Lichens of Minnesota," by Professor B. Fink of Miami 

 University, Oxford, Ohio, is based on extensive field work under 

 the auspices of the Geological and Natural History Survey of 

 Minnesota extending over a period from 1896 to 1902. In the 

 preparation of the text since the latter date, the libraries of the 

 United States Department of Agriculture at Washington, the 

 Lloyd Botanical Library at Cincinnati, and the library of the Mis- 

 souri Botanical Garden have been consulted. 



In this work the treatment of generic names is in accordance 

 with present usage and synonyms are omitted except the citation 

 of the first binomial used where a species has been transferred 

 from the genus in which it was originally described. 



The preliminary chapter consists of a concise treatment of the 

 origin and nature of lichens, their morphology, reproduction, and 

 economic bearing. While it is noted that some botanists hold 

 that the lichens should be distributed among the fungi, no attempt 

 has been made to do so in this paper. 



The body of the work contains keys to the genera and descrip- 

 tions of the families, genera and species. More than three hun- 

 dred species are described and many of them beautifully illus- 

 trated with half-tone cuts. While the title of the work would 

 indicate that it is restricted in its scope, the lichens of Minnesota 

 are typical of many other localities and the work will be found to 

 be of great value to students interested in this group of plants. 

 The entire work comprises 269 + xvii pages of text and 51 plates, 

 besides a number of text figures. — F. J. Searoer. 



The Genus Fimetaria. — With reference to the substitution of 

 Fimetaria for the generic name of those fungi commonly included 

 in the genus Sordaria, the following criticism appears in Ann. 

 Myc. 9 : 192 : "Aus welchem Grunde der allbekannte Gattungs- 

 name Sordaria durch den neuen Namen Fimetaria ersetzt wirt ist 

 nicht ersichtlich. Jedenfalls ist diese Umnennung nicht zu billi- 

 gen, wie auch in der im Jahre 1901 erschienenen monographischen
