Contingent Phases: (a) Blackening, (b) Reduced. 
Substrata: On trees ( Juniperus ) and shrubs, rarely on old wood. 
Distribution: Not uncommon in the Austral Zone, extending just to the 
base of the Transition on the Atlantic seaboard and islands from Massachusetts 
to Mississippi. 1 2

Observations: This species, evidently a near 
relative of R. complanata as judged by cortex and 
spores, is distinguished by its generally terete and 
tuberculate laciniae and large subterminal spurred 
apothecia. The characteristic habit of the plant 
as it grows in spherical, rosette-like tufts on the 
twigs of Juniperus serves to distinguish it in situ from other Ramalinas. It has 
plainly never been described, through a long confusion, and, therefore, I propose 
for it here a new name, given in honor of Henry Willey, because of the abund- 
ance of the species in the region in which he collected; the type locality being 
one of his favorite collecting grounds. 
R. tenuis 2 Tuck was made a synonym of R. gracilenta . 3 by Nylander, as 
it may be, both having fusiform spores. R. gracilenta , as compared with R. 
gracilis, is not a compressed species although placed by Dr. Zahlbruckner under 
Wainio’s Compressiusculae. It was suggested by Mr. Merrill that R. tenuis 
should be revived for the present species, but though Tuckerman did not men" 
tion the spores in his diagnosis, material determined by him as tenuis shows fusi- 
form spores and cannot be separated from R. Montagnei De Not. 
Tuckerman later made his tenuis synonymous with rigida, but his understanding 
of the entire group is impossible of elucidation. 
R. rigida ( = attenuata ) is the West Indian species bearing small, lateral 
apothecia with small subfusiform spores.
