Sylloge Fungorum.’—Volumes XIX and XX of this extended work, 
bearing the subsidiary title Index Iconum Fungorum, contains a oe 
index to illustrations of fungi, and includes references to works of m h 
early as well as the more recent authors. References to iho are indi- 
cated briefly but clearly; synonyms are introduced frequently and serve as a 
ready and unmistakable means of cross reference. Volume XIX enumerates 
alphabetically the genera A brothallus to Lysurus inclusive, and Volume XX 
continues with Macowanites to Zythia. The species under their respective 
genera and the bibliographical references thereto are likewise in alphabetical 
sequence, and the terminology is in accordance with the international rules of 
botanical nomenclature. The amount of detailed and painstaking labor 
involved in the achievement of such a task is enormous, but the final result in 
this case is a valuable work of reference, indispensable to the wis eeett and 
helpful to the general student of botany.—J. M. GREENMAN
