230 PROCEEDINGS OF THE AMERICAN ACADEMY 



Opegrapha atra, Pers. — Trees, Hawaii (Remy), Nyl. 1. c. ; 

 Oahu (Mann). 



Opegrapha lentiginosa, Lyell. — Trees, Oahu (Mann). 



Graphis scripta (L.) Ach., emend. — Trees, Oahu (Mann). — 

 Var. assimilis. G. assimilis, Nyl. — Oahu (Mann). 



Graphis discurrens, Nyl., var. Kaalensis: apotheciis crassi- 

 oribus dendritico-ramosis ; sporis (octonis) majoribus 8-blastis. — 

 Trunks, Kaala Mountains, Oahu (Mann). — A larger plant than the 

 Lichen (Hong Kong, Wright) described by Nylander, and with rather 

 the aspect of conditions of G. vemicosa, Fee. 



Graphis elegans (Sw.) Ach. f. striatula. G. striatula, (Ach.) 

 Nyl. — Trunks, Oahu (Mann). Var. substriatula. G. substria- 

 tula, Nyl. — With the last (Mann). 



Graphis rigida (Fee) Nyl. — Trees, Oahu (Mann). 



Graphis fulgurata, Fee, e descr. — Trees, Oahu (Mann). — 

 Small, with a little of the aspect of G. discm-rens, a, the colored spores 

 of which species also look towards the section represented by G. den- 

 dritica ; but approaching more evidently to the latter, with which it 

 was arranged by Fee, in its open disk. 



Graphis dendritica, Ach., excip integro. — Trees, Waialua 

 Mountains, Oahu ; and Hawaii (Mann). Var. ixusta. G. inusta, 

 Ach., Nyl. — With the last, Oahu (Mann). Var. leucocheila. G. 

 leucocheilce (Fee) Nyl. prox. accedens. — Trees, Kaala Mountains, 

 Oahu (Mann). — The Oahu Lichen last named has the habit of large 

 forms of G. scalpturata, Ach., in which the thalline margin is conspicu- 

 ous (Lindig, Lich. N. Gran. n. 54, coll. 2 dae ) but the spores of G. den- 

 dritica ; differenced here, as commonly in the Carolina Lichen, by an 

 occasional passage of one or more of the sporoblasts into two, — the 

 beginning of the muriform-multilocular stage. And it certainly sug- 

 gests that G. scalpturata (compare especially the specimen of this in 

 Lindig's n. 752 with that of G. dendritica in n. 2,563 of the same 

 collection) is only a condition (the ultimate one as respects sporal de- 

 velopment) of G. dendritica ; analogous to G. scripta, var. sophistica. 

 (G. sophistica, Nyl.) 



Graphis patellula (Meissn.) Nyl. in litt. Opegrapha, Meissn. 

 in Fee Suppl., Lecanactis, Nyl. Enum. Var. paterella. Leca- 

 nactis, Tuck, in litt. — Trees, Oahu (Mann). — Spores (as in the 

 Carolina Lichen) 8 - 10-locular. Those of Fee's Lichen are described 

 by him as 15 - 18-locular.
