THE LICHEN FLORA OF QUEENSLAND. 



81 



The transactions of the (British) Linnean Society, and the 

 proceedings of the various Australian and New Zealand scientific 

 societies have been searched for descriptions of Queensland plants ; 

 and reference has been made to the different colonial floras, and to 

 the works of such lichenologists as Nylander, Leighton, Miieller, and 

 Fee, extracts from which, and from other sources, are acknowledged. 

 Full use has also been made of the lists of lichens published in the 

 Synopsis and in its first and second supplements. The descriptions 

 are mainly from the plants themselves. 



The classification followed is that of the most recent Nylan- 

 derian arrangement as given by the Rev. J. M. Crombie in 

 " Grevillea." 



The letters before the descriptions show by whom the determination 

 has been made ; thus — 



K = Knight Sn = Stirton 



L = Leighton Sy = Shirley 



M = J. Miieller W = Wilson 



B = Berkeley 



LICHENES. 



Family 1— Ephebacei, Nyl. 



Thallus filiform, or branched and fruticulose ; gonimia (i.e. 

 granula gonima) forming a single central axis, or large and 

 in transverse series, or smaller and subtransversely arranged 

 in little heaps, 2, 4, or more together. Apothecia concolorous 

 and biatorine, or lecideino and lenticular, or endocarpoid, 

 Spermatia oblong or cylindrical. 



Tribe I — Sirosiphei, Nyl. 



Mycelial growths having close affinities with algas, crustace- 

 ous or felted, dark-brown or black, coating damp rocks or 

 soil. 



I. — SI ROSIPHON. 



Thallus filiform, the threads composed of 1-seriate cells, or 

 through constant division, the cells in layers several rows thick ; 

 mostly coloured and jelly-sheathed. Border cells (often to two or 

 more) interstitial in the threads, with the spore cells between tbem.
