Note: Ramalina subpellucida Mull. Arg. Flora, 46 : 492, 1888, is a species 
described from “prope Coamo,” Porto Rico, with a variety tuberculata also. I 
have seen neither plant. Porto Rico lies out of the region covered by this paper, 
but the species or its variety may be looked for in Cuba. 
Note: Alectoria thrausta Ach. Lich. Univ. 596. 1810. This species was 
described as follows: “thallo tereti-compresso ramoso albo basi nigro, ramis 
inaequalibus flexuosis fibrillosis flexuoso-cirrosis.” 1 . c. The type localities 
given are “Helvetia,” “Gallia.” It was moved into the genus Ramalina by 
Fries in 1831, and was considered a Ramalina by Schaerer and Nylander. Until 
it is found in a fertile state the arguments in favor of Acharius’s disposal are two- 
fold: terete laciniae, and cortex of simple structure. There are no good argu- 
ments for considering it a Ramalina, and I, therefore, am not including the 
species in the present paper. 
In closing this paper on the Genus Ramalina I want to thank most heartily 
all those who have so graciously aided me in its preparation. It is my hope that 
the paper will prove of value in studying the species of this difficult genus, and 
that by the time I shall have embodied its text in my Monograph of the Usnea- 
ceae of the United States and Canada any errors or omissions that have been 
found will have been brought to my notice.

Arg. redescribed this species under the name Ramalina Sintenisii as follows: 
“hucusque sterilis tantum nota, nunc in Porto Rico frequenter et hinc inde 
fertilis lecta, species distincta est et a proxima R. rigida Nyl. habitu longe vali- 
diore, apotheciis omnibus lateralibus et sporis multo longioribus et ambitu multo 
angustioribus differt. — Thalli albidi laciniae elongatae, 4-16 cm. longae, inferne 
dichotome, superne racemosim ramosae, hinc inde elongato-ramiferae, compres- 
sae, 1-2 mm. latae, ad dichotomias latiores, ad margines tuberculis variis acute 
prominentibus albidis asperae, caeterum laeves et laevigatae, haud sulcatae nec 
striatae, utraque facie plano-convexae ; apothecia omnia lateralia, 2^-4 mm. 
lata, plana, subcarneo-pruinosa, marginata, margo tenuis, prominulus; sporae 
acutatae, rectae. et parce curvulae v. leviter sigmoideae.” “prope Hato Grande,” 
etc. From the description the plant seems a near relative of R. usnea.
