Mr. Merrill states that “No American specimens of the R. rigida ( = R . 
Willeyi ) stock have yet been examined showing a medullary coloration on ap- 
plication of KOH.” This, again, distinguishes it from the foregoing species, 
though I have found examples that show a distinct coloration. Dr. Herre re- 
corded rigida from the California coast (Proc. Wash. Acad. Sci. 7:335, 1906, 
and 12 : 221. 1910), but an examination of his material does not permit me to 
include it here; it appears to be a rather young and as yet esoraliate state of 
R. farinacea, the plant often determined as the variety minutula Ach. Dr. 
Eckfeldt also records it from Labrador and Newfoundland, seemingly erroneously, 
and records from Cuba and Jamaica are referable to the foregoing species. Mr. 
Merrill has remarked that R. canaliculata Fr. is also often mistaken for this 
species. Small states, otherwise typical, are frequently met with from Florida 
(phase b).

Note: Ramalina rigida var. dendroides Nyl. Recog. mono. Ram. (14) 112. 
1870. This form, or variety, has been recorded (Hue, Lich. Exoti., 261. 1890) 
from the Antilles. I have seen no material, and can add nothing to our knowl- 
edge of the plant from within our area, though it seems hardly separable from 
R. complanata. It was described as follows: “thallo compresso (altit. 8-12 
centim., latit. basi circiter 1 millim., crassit 0.5 millim. vel tenuiore) rigente 
dendroideo-ramoso et ramuloso, etiam ibidum occurrit.” Type No. 460. Coll. 
Husn. from “Martinica.” 
Ramalina dendriscoides Nyl. Flora 34:412. 1876. This Cuban species I 
have not observed. It was defined as follows: “Thallus pallidus subnitidiusculus 
minor gracilis (altit. 2-5 centimetr., crassit. o. 5-0.6 millim. vel gracilior), teretius- 
•culus, dendroideo-ramosus et ramulosus, ad axillas interdum vage impressus, 
ramulis saepe apicibus albo-sorediosis. Apothecia non visa. Datus. No. 738. 
Species videtur propria accedens ad R. rigidam vel saltern ejus stirpem. 
R. dendroides (Del. Nyl. Ramal. p. 14) differt jam thallo majore, laciniis com- 
pressis et defectu sorediorum terminalium ramulosum. R. sorediantha com- 
parari forsan etiam possit ob soredia, sed haec species thallum non habet teretius- 
culum (sed canaliculatum, etc.).” /. c. 
Ramalina camptospora Nyl. Recog. mono. Ram. 120 (22). 1870. This 
species, of which I have seen only the type at Paris, was described by Nylander 
from Cuba as follows: “Thallus stramineo-pallidus compressus tenuis (basi 
latit. 1 millim. vel magis attenuatus) linearis, lineari-divisus et ramis utroque
