Hab. Coast of Hawaii. — I refer this Lichen, with some confidence, 

 to the species indicated by Eschweiler; which extends, if this view be 

 correct, to Venezuela (Mr. Fendler) and Cuba (Mr. Wright), and even 

 to Florida. Taylor's specimens, probably not distinguishable, were 

 from Demerara. O. isidiodada, Montag. & Van den Bosch, in Mont. 

 Syll. p. 336, and Lich. Javan. p. 31, to judge by specimens which I 

 owe to the kindness of the authors, is exceedingly near; and C. pul- 

 chella (Schwein.) Tuckerm. Suppl. in Amer. Journ. Sci. 1858, p. 427, 

 is possibly only a smaller state, less perfectly developed than the tropical 

 Lichen, and approaching more closely to states of the northern species. 

 G. Mitrula, Tuckerm., and C. decorticata, Flcerk., with which last our 

 plants have much in common, are analogous, normally symphycarpous 

 forms of the brown-fruited series. 



The artist has given two figures of clumps of the Hawaian Lichen, 

 which exhibit its short and stout habit ; a feature, in which it differs from 

 the South American specimens, which are all slender, and some of them 

 rather elongated. The other figure is from a drawing by Mr. Sprague, 

 and presents in a, a magnified view of a section of the summit of a 

 podetium, with its inflated symphycarpous apothecium; and in b, a 

 section of the disk of an apothecium, showing the spore-bearing layer 

 (thalamium) , the paraphyses, and several spore-sacks (thecce) ; with the 

 simple, ovate-ellipsoid, hyaline spores, common to many species of the
