The infected termite was collected in Samoa by Dr P. A. Buxton and was identified by Mr G. F. Hill, Melbourne, who noticed “foreign bodies” attached to the forelegs. These bodies proved to be fructifications, in the form of small apothecia, of a fungus to which the name Ectomyces caloterni n.g., n.sp., has been given. The two infected legs comprised all the available material, and, as they were preserved in alcohol, cultivation of the fungus could not be attempted.
