ALPINE ROSE APPLE. This is the popular 
name for a very characteristic gall-like excrescence oc- 
curring on the leaves of Rhododendron hirsutum and 
R. ferrugineum, two of the most extensively planted 
of alpine shrubs. They vary considerably as to size and 
texture, but are of a dirty creamy-white, tinged on the 
sunny side with a bright pink, and in summer are covered 
with a kind of bloom. The fungus responsible for the 
malformation is Exobasidiuwm Rhododendri, of the group 
Basidiomycetes, to which belong several of the most 
destructive tree-fungi in Agaricus and Polyporus, as well 
as some of the most useful, considered from an economic
