lirellae plano-concave, with the cut off edge of the sur- 

 Sn. rounding thallus spuriously margined, not depressed.

 intensely fuscous, -014 — 016 x -005 — -007 m.m Lich. 

 Beit. XXV. 7, 12. 



Hub — Rockhampton, on rocks. 



■6. G. cyclospora, Mull. Arg. 



Thallus argillaceo-flavicant, thin, determinate, towards 

 the margin shining, smooth : stromata orbicular, 2 — 3 

 m m. in diameter, at length variously confluent, scarcely 

 or not at all emergent, ca?sious, subpulverulent ; lirelhe 

 closely radiately disposed, punctiform-linear, both simple 

 M. and furcate, to *12 m.m. wide; disk black, very narrow, 

 perithecium above nigro-fuscous, not at all thick, towards 

 the base evanescent ; hypothecium hyaline ; paraphyses 

 very thick and easily separating; spores in linear asci, 

 1-seriate, brown or black-brown, globose-ellipsoid, -008 — 

 •012 x 007 — '009 m.m., from bilocular at length various- 

 ly subcruciately 4-locular.

Hab. — Trinity Bay, on bark. 



7. G. colliculosa, C. K. 



Thallus pallid, olive yellow, cartilaginous, thick, coilic- 

 ulose ; stromata subrotund or shapeless, convex, cinereo- 

 pruinose ; lirellai intricate-ramose or confluent, black ; 

 hymenium rising from a thick black torus ; paraphyses 

 adhering, obscure, grumose, apices brown : spores oblong, 

 K. at both ends rounded, 3-septate, palely fuscescent, finally 

 brown, -013 x -005 m.m. From G. confluens which it 

 resembles outwardly, it is readily separated by the shape 

 and colour of the spores.
