The host is endemic, and is widespread. (Cheeseman, 1906, p. 563.) 
This species forms large fusiform swellings on the branches of the host ; 
as a rule it occurs on laterals, forming “ witch's-brooms," but 16 is not 
gl 
taken from average spores, for if the lachrymiform ones were measured they 
would give an entirely erroneous impression as to the average size, they 
being more than twice as long as the average spores 
t is probable that the mycelium is perennial, as the fungus may be 
obtained throughout the year from infected plants.

Distribution: Victoria; New South Wales; Tasmania. 
The host is endemic, and, although not uncommon in the South Island, 
is confined to a few localities in the North. (Cheeseman, 1906, p. 571.) 
This species is characterized by the scattered, small-sized aecidia.
