From the foregoing it will be seen that in New Zealand this species has 
been collected on aecidia, caeomata, uredosori, and teleutosori. 
tain sori, indeed, it is difficuit-to obtain any unaffected spores. Generall 
the pycnidia are ‘superficial and easily seen, but in certain cases, тетер 
when they are parasitic upon aecidia, they are almost compete rsed, 
and their deus noted only when sections of the aecidia are examined 
Saccardo (Syll. Fung., vol. 3, p. 410, 1884) states that the spores have on 
either end a few fine bristles; I have failed to observe these, EE I 
have examined numerous microtome sections of pycnidia of all a So 
common are the pycnidia on certain species that they have fequi been 
mistaken for spermogones, and described as such.
