The host is indigenous and widely дбайна along е coast; it occurs 
also in Australia and New Caledonia (Cheeseman, 1906, p. 850). 
Osborn (1922) has recorded the pathological changes this species effects 
in the host. The inflorescences, both male and female, become considerably 
modified, the anthers become sterile, and the filaments do not clone 
and the various organs are modified in number, structure, and position 
Germination, according to McAlpine (l.c., р. 174), does not occur in water, 
but takes place ceil | in nutrient solution. A four-celled probasidium 
is produced, and on this are borne the conidia. These multiply by budding, 
but before the solution is exhausted the conidia m produce hyphae which, 
they reach the air, form abundant aerial co 
I bn failed to germinate the spores either in i iion or nutrient solution, - 
but the material was probably too old, for it has been kept in the herbarium 
for twenty-one months.
