13. G. persulcata. Stirton. 



Thallus smooth, even, shining, glaucous; lirellse 2 — 3 m.m. 

 long, simple, straight or slightly wavy or simply bent or 

 curved, often divided by transverse fissures into 2-4 parts, 

 each part attenuate and constricted at the fissure ; thaliine 

 margin distinctly defined in early stages ; lips finally 

 Sn. raised, emergent, blunt, black ; epithecium (disk) showing 

 as fine concolorous line, or in parts with vestiges of a 

 thaliine covering ; perithecium nigro-fuscous, attenuate or 

 wanting 1 below ; paraphyses slender, short, somewhat 

 readily separating ; spores hyaline, immature. 



Hab. — Indooroopilly, on bark. 



14. G. malacodes, XyL 



Thallus thin, cinerascent or pale glaucous ; lirellaj to 3 

 m.m. in length, sparingly (1—5) branched, branches 

 usually curl back towards parent canal ; epithe ium black, 

 hoary, -2 m.m. wide ; thaliine margins raised, distinct, 

 Sn. deeply sulcate, in parts fissured ; perithecium fuscescent- 

 pallid or sub-fulvous ; spores 8, linear-oblong, at both ends 

 somewhat obtuse, 7 — 10 locular, hyaline, deep blue with 

 iodine, -06 x -008 — -01 mm.; paraphyses slender, tips

15. G. subtenella, Mull. Arg.

 extremities acutely angustate, 1 m.m. wide and narrower, 

 black, slightly emergent, lips at length deeply 1 -sulcate : 

 lips of perithecium in section above broad and black,

 M. or hyaline ; hypothecium subhyaline ; spores 8, hyaline, 

 •025— -03 x -006— 007 m.m , 8—10 locular, at both ends 

 obtuse. Differs from G. tenella in the sulcate lirelhe and 

 dimidiate perithecium; and from G. leptoclada in the
