Causes swellings that form masses from y^ to 2 or 3 

 inches in diameter on roots of alders. Each swelling 

 consists of crowded outgrowths often branched dicho- 

 tomously, ending in short, warty, cylindrical, truncate 

 branches. In the inner cells of the hypoderm the 

 fungus bores its mycelium, and foims in the cells swell- 

 ings on the threads, which become crowded into a dense 

 mass filling each cell.

* Rhytisma acerinum Fr., forma punctatum Fr. 



On Acer pseudo-platanus L. Near Aberdeen. Pro- 

 fessor J. W. H. Trail. 



Rhytisma punctatum Fr., was formerly given as a separate 

 species (C. Hbk. No. 2280. S. Mycol. Scot. No. 1788), 

 though a doubt was expressed in " Handbook " whether 

 they were really distinct. There can be no doubt that 

 R. pimctatum is merely a form of R. acerinum.
