A SINGULAR CORDYCEPS FROM STEPHEN 
ISLAND, NEW ZEALAND. 
By G. H. Cunningham, Wellington, N.Z. 
At the north-west extremity of Cook Strait, about three miles 
from D’Urville Island, the nearest land, lies Stephen Island, a 
small area one and a quarter miles in length and rising to a 
height of goo feet above sea level. The island is for the most 
part open tussock country with, in the more sheltered localities, 
a few isolated patches of wind-swept forest. 
Although only 370 acres in extent Stephen Island rejoices in 
the possession of a somewhat unique fauna. Here are found the 
tuatara, Sphenodon punctatus Gray, which occurs in thousands 
and appears to be slowly increasing in number; Deinacrida 
rugosa Buller, a huge weta, found in only one other locality; 
a Discoglossid frog, Liopelma hamiltoni McCulloch, a recently 
discovered species confined to this island, where its habitat 
appears to be the crevices under large boulders; and a now 
extinct wren, Tvaversia lyallit Roths. 
With the single exception of the Cordyceps described below, 
the flora possesses no peculiar features, as there are no endemic 
species.
