THE LICHEN FLORA OF QUEENSLAND, 



4. C. boiyrosum, C. K. 



Thallus densely velvety, golden-yellow-green, formed from 

 globose gonidia (-025 m.m. wide) together with a few very 

 slender filaments ("002 m.m. thick), gonidia cohering by 

 very short funiculi, either concrete or joined in a long chain. 

 K. Apothecia pallid golden, plane ; margin paler; hypothecium 

 colourless ; paraphyses clavate, subdiscrete. "Spores 8, in 

 clavate asci, uniseptate, ellipsoid, colourless, '01 x *004 m.m. 

 Plumbeo-casrulescent gonimia in hyaline nodules occasionally 

 found in the neighbourhood of the apothecia, imbedded in 

 the midst of bright green gonidia. Closely allied to C. 

 moniliforme. 



Hob. — On bark, Mt. Perry. 



Dr. 0. Knight, Syn. Queen. Flora, 1st Sup. 



5. C. rigidulum, Mull, Arg. 



Thalline filaments about ^ m.m. long, effuso-easspitose, 

 variously and intricately implexed, deflexed or ascendant, 

 rather rigid, viridi-aaruginose, moniliform, joints about *022 

 — -024 m.m. wide at the centre to -013 — -015 m.m. at the 

 M. extremities, ellipsoid or at length globose-ventricose, about 

 three times longer than wide, superficially hyphemoid- 

 hirtellose ; apothecia unknown. Near C. moniliforme, 7'uck., 

 from which however it differs in the colour an 1 much greater 

 diameter of the filaments. 

 Hab. — On bark, near Toowoornba. 

 Lich. Beit. v. Dr. J. M. XVI. 8. 



Tribe XVII.— Graphidei. 



* Thallus crustaceous with chroolepoid gonidia ; apothecia 

 gymnocarpous, either orbicular or lirelliform. 



Sub-tribe 1 — Biatorinopsidea?, Mull. Arg. 



Apothecia orbicular-biatorine, simply margined, thalline 

 margine none ; disk not urceolate. 



* Fxom this stage, ami partly in Eulecanorei, the classification is mainly 

 that of the eminent lichenologist, Dr. J. Muller, of Geneva.
