L. farinosa, Ach., L. Dilleniana, Ach., L. abietina, Ach., L. premnea, 
Ach., and the above Lichen are very closely allied. The New Zealand 
Lichen approaches closely L. abietina, Ach., from which it differs principally 
in the greater number of septe in the spores and the smaller apothecia.

Dr. Stirton, in his additions to the Lichen Flora of New Zealand, 
published in the “‘ Journal of the Linnean Society,” has transferred Lecanora 
implicata to the genus Lecidea. The Lichen, however, is a true Lecanora, 
and a variety only of Lecanora parella, as I pointed out in a paper pub- 
lished in the “ Trans. N. Z. Inst.,”’ Vol. VIL., p. 357.
