it from R. canaliculata Tayl. Its only distinct character is the membraneous 
thallus which separates it from all the members of what had been known as the 
calicaris stock; and its medium to large apothecia and curved spores always 
distinguish it from yemensis. Nylander considered it closely allied to his sub- 
fraxinea, a species of which only the form firmior he attributed to our area, as 
already cited, and this form approaches closely true fraxinea. It is certain 
that Menziesii is very closely allied to this latter species, separated at times 
only by its more membranaceous thallus. No true puberulence has ever been 
observed. There are certain evidently young states, canaliculate and less mem- 
branaceous, that are comparable with the most developed condition of R. line- 
aris. In fact, only a long and careful field study throughout the range can ever 
settle the exact limits of the species.

Note: Ramalina fraxinea var. calicariformis Nyl. Recog. mono. Ram. 
136 [36], 1870, which was attributed to California by Nylander and l’abbe Hue, 
seems to be very much like the younger states of Ramalina Menziesii Tuck.- 
or at least what have been taken for the younger states of this species. Ny, 
lander diagnosed it as follows: “Thallus attenuatus (altit. 3-12 centimetr.), 
facie sicut in R. calicari; apothecia marginalia et subterminalia (haec laciniola 
terminali subreceptaculo appendiculata). Sporae [curved] longit. o. 010-17 
millim; crassit. 0.004-6 millim.” Though I have seen the type and l’abbe 
Hue’s material, a further study based on much more material is necessary. 
Ramalina subfraxinea f. firmior Nyl. Recog. mono. Ram. 139 [41], 1870, was 
attributed to Mexico by Nylander. I have seen no specimens except the type, 
preserved at Helsingfors, which was diagnosed as “thallo nigrescente. Magis vero 
notabilis est,” by Nylander. Ramalina polycarpa Nyl. Recog. mono. Ram. 
140 [42], 1870, was described from Mexico by Nylander. Though I have seen 
the species from New Zealand I have not met with other material than the 
type (and one plant from Warrnambool, Victoria, Australia) which is preserved 
at Helsingfors. Nylander defined the species as follows: “Facie fere Ramalinae 
fraxinae minoris (altit. 2-6 centimetr.), apotheciis alboglauco-suffuds minoribus 
(latit. 1-2 millim.), sporis tenuioribus (minusque curvis, longit. 0.010-16 mil- 
lim., crassit. 0.004-5 millim.)”
