" Beitraege zur Morphologie unci Physiologie der Pilze, 



von A. DeBart und M. Woronin. Fuenfte Reihe. Beitrag zur 

 Kentniss der Ustilagineen, mit vier Tafeln."— In this important 

 contribution to Mycological literature we .have an attempt to form 

 a philosophical system of classification of the Ustilaginece upon the 

 peculiarities of spore growth and "sporidia" production. It is quite 

 needless to say that it is based upon the quiet assumption that the 

 time has come for giving life history more, and a single phase of 

 life history less weight in our systems of classification. Of course 

 beside -the leading idea of the contribution many isolated facts of 

 value find place in this clearly written and beautifully illustrated 

 memoir. We can only give the more important in this brief resume. 



Plate I represents Tuburcinia Trientalis, which in its conidial 

 state covers the under side of the leaves of Trientalis Europwa, L. 

 The specimen was taken early in June. Sections made through the 

 young leaves of the host show an abundant ramification of the 

 cross-partitioned hyphse beneath the epidermis, and between and 

 into the chlorophyll-bearing cells. These threads reach the air 

 either through a stoma, or sometimes directly between the epidermis 

 cells. Some of the escaping threads creep in a tortuous manner 

 over the leaf surface ; others are erect and terminated by a single 

 inversely pear-shaped conidium. Sowing these conidia on a grow- 

 ing Trientalis leaf and after a short time removing the epidermis it- 

 will be seen that the conidial threads have reached the interior of 

 the leaf between the cells of the epidermis. 



Plate II gives the condition of affairs in late summer, when a 

 transverse section through the stem shows spore masses in the
