Die Pilz thiere oder Sehleimpilze. Von Dr. W. Zopf. [Encyclopnedie 

 der Naturwissenschaften. Breslau, Eduard Trewendt, 1885] . 



Owing to the advances made in our knowledge of the Mycetozoa 

 since De Bary's remarkable work (1864), and also to the fact that 

 Eostafinski's Monograph of the group is written in Polish, and thus 

 inaccessible to most botanists, the want has arisen of a treatment 

 of these organisms embodying the scattered results of the last 

 twenty years' work. Dr. M. C. Cooke has given us an extract 

 from Eostafinski's Monograph, so far as it has reference to species 

 found in Great Britain ; but the student of the group demands 

 more than such a glimpse into this comprehensive work, and it is 

 to be regretted that the whole Monograph was not then rendered 

 into intelligible language. 



In De Bary's ' Vergleichende Morphologic und Biologic der 

 Pilze, Mycetozoen und Bacterien,' published last year, the group 

 received the same treatment as the others in the book, and this 

 had the special interest of being furnished by the author of the 

 work which first threw light upon the life-histories and relation- 

 ships of these extraordinary organisms. 



Dr. Zopf has divided his present treatise into three sections ; 

 the first dealing with the Morphology and the second with the 

 Physiology. These parts of the subject are thoroughly dealt with, 

 and of very special interest. De Bary's recent discussion (just 

 referred to) of the same subject perhaps makes one feel less 

 indebted than one should to Dr. Zopf for his painstaking and 

 original labour. The third section, which is perhaps the most 

 valuable, is devoted to the systematic grouping of the Mycetozoa. 

 Dr. Zopf's classification is as follows : —
