OF ARTS AND SCIENCES: SEPTEMBER 11, 1866. 231 



Graphis frumentaria, Fee, var. ciilorocarpa, Nyl, G. chloro- 

 carpa, Fee. — Trunks, Oabu (Mann). 



Graphis tumulata, Nyl., e descr. — Trunks, Oahu (Mann). — 

 Spores brown, cocciform, submuriform (transverse series of sporo- 

 blasts four ; longitudinal, one to tbree), as described in the cited spe- 

 cies, from New Caledonia. 



Graphis oscitans (sp. nov.) : thallo tenui contiguo sequabili albo; 

 apotbeciis innato-prominulis simplicibus subramosisve flexuosis, mar- 

 ginibus excipuli profunde canaliculati nigricantis tenuibus, dein hianti- 

 bus nudis, cum thallino crassiusculo concretis, hypothecio incolore. 

 Sporse octonos in thecis, mediocres, oblongge, submuriformes (ser. tr. 

 6-8, long. 1-2) diam 3-3|plo longiores, fuscescentes. — Trunks, 

 Oahu (Mann). — With the aspect of the closed apothecia of G. dimor- 

 pha, Nyl., and agreeing in size ; but not assuming the habit of G. den- 

 dritica ; and better comparable with species of the present group. 



Graphis grammitis. Fee. — Trunks, Waimea, Kauai, and moun- 

 tain of West Maui (Mann). — One of the sporoblasts now divided 

 into two ; an indication of the true type of this decolorate spore. 



Graphis radiata, Nyl. — Trees, Oahu (Mann). — One of the 

 specimens resembling Fissurina nitida, M. and v. d. Bosch. Lich. Jav., 

 which I take to be the Java Gr. radiata of Nyl. Eimm., — the first 

 named authors not having had the advantage of comparing the Lichen 

 with Eschweiler's Diorygma nitidum ; — and the other smaller, and 

 more like G. radiata as published in Lindig's New Granada Lichens. 

 The spores of the forms named scarcely differ. There is still another 

 of these debased types of Graphis (Oahu ; Mann) intermediate in the 

 size of the apothecia between the coarser and slenderer forms just 

 noticed, but otherwise similar, which is remarkably differenced by the 

 colored (cocciform and regularly quadrilocular) spores ; suggesting G. 

 heterospora, Nyl., of Bourbon : the only described instance of colora- 

 tion in the present section (Fissurina). 



Fam. 3. Glyphidei. 



Chiodecton perplexum, Nyh — Trees, Kaala and Waialua 

 Mountains, Oahu (Mann). 



Gltphis heteroclita, Mont. — Trees, Kaala and Waialua Moun- 

 tains, Oahu (Mann). 



Glyphis Achariana, Tuck. Suppl. 1858. G. cicatricosa and G. 

 favulosa, Ach., and G. conjluens, Mont. — Trunks, Oahu (Mann).
