Mycologia 
This species was described from material collected on the bark 
of some coniferous tree in Newfoundland. The type has been 
studied and both the habitat and general characters of the plant 
indicate that it is a Pithya, which genus is rather closely related to 
Lamprospora. Whether it is a distinct species I am unable to say. 
The plants are larger and more convolute than most specimens of 
Pity a vulgaris Fuckel, but some specimens of this species ap- 
proach it in size. If it is not the same species, Ellis’s plant is at 
least very closely related to P. vulgaris.
