the spores, while the notes following the description of each species 

 add greatly to the value of the book. 



A complete fungus flora of Britain, such as exists, e.g., for Germany, 

 is greatly to be desired, and if it were done in the same complete 

 and capable fashion as the present section it would be of immense 

 service to all mycologists and, through them, to the general public. 

 The book is well printed on good paper, and altogether one we can 

 warmly commend to everyone whose work or pleasure lies in the study 

 of the Uredinales. 



" Garden Trees and Shrubs. Illustrated in Colour." By W. P. 

 Wright. 8vo., 337 pp. (Headley, London, 1913.) 12s. 6d. net. 



This is a sumptuous work of some three hundred and thirty pages 

 — well written, nicely got up, and beautifully illustrated. The list 

 of new trees and shrubs is particularly valuable, and already many 

 of the introductions from China have been found well suited for 

 cultivation in this country, and apparently quite hardy. We could 

 have wished that the list of trees and shrubs had been extended, as 

 it is difficult in the small space allotted to such genera as Pyrus 

 and Berberis to do them the justice they deserve in the matter of 

 description and cultivation. 



Some excellent advice is given in chapter vii. on " Mistakes in 

 the Culture of Trees and Shrubs," advice that we would like to see 

 carried out in a greatly extended fashion in the formation of wood- 

 lands and shrubberies. Imperfectly prepared soil, careless planting, 

 and want of attention to the individual requirements of trees and 

 shrubs are all evils to be guarded against. In some of the chapters, 

 such as those on seaside and town planting, several of the most valu- 

 able species have escaped notice, but in such a comprehensive work 

 omissions of this kind may purposely occur. We are glad to see that 

 a chapter is devoted to pruning shrubs and trees, for this operation 

 is but little understood, as is also the proper time at which pruning 

 should take place. Different trees and shrubs have widely different 

 habits of growth, and so it behoves us to study well these peculiarities 

 before the pruning-knife is applied. In the matter of hedges the 

 author gives sound advice J while the list of shrubs for planting in 

 the shade is extensive, and supplemented for the first time by that 

 useful Chinese shrub Sarcococca ruscifolia. Altogether the book is 

 most useful, and may equally well grace the library of the gardener 

 or the drawing-room table. 



Regarding the illustrations we cannot speak too highly, and the 

 author is certainly to be congratulated on getting together so 

 meritorious a work. 



" Mildews, Rusts, and Smuts." By G. Massee and Ivy Massee. 

 8vo., 229 pp. 5 plates. (Dulau, London, 1913.) ys. 6d. net. 



It is long since a book containing descriptions of all the fungi 

 contained here and native in Britain has been published. The last
