 black-brown, innate, with thick raised thalline border or 

 nearly naked ; epithecium subconcave or flattish, width 

 Sn. -2 — -3 m.m. ; spores 4 — 8 uncolourecl, fusiform or oblong- 

 fusiform, 10 — 17 locular (loculi with 2 — 4 cellules per 

 row), -054 — -075 x -009 — '012 m.m., paraphyses very

Hab. — Brisbane and Rockhampton, on bark 

 Syn. — G. brachyspora, Mull. Arg. 



Note. — Two parasitic species have also been named, but from immature or 

 incomplete specimens ;— Graphis parmeliarum, C.K., when fertile 

 apothecia offer themselves, is likely to prove a synonymn of Melano- 

 grapha asteriscus, Mull. Arg. ; Graphis Flindersias, Shirley, was 

 found on herbirium specimens of Flindersia maculosa, the gift of 

 Mr. F. M. Bailey, who had not however observed the parasite on the 

 leaves. The lirellae are 3—4*5 m.m. long, simple, almost straght r 

 with raised thalline margin, terminations acuminate; disk dark, 

 rimiform ; spores immature.
