OEDER LICHENES. 



tJsnea angulata, Hook et Tay. 



Hab. On trees Taylor's Range. (Bailey.) 



Alectoria, Ach. 



A. australiensis, G. Knight. Sp. Nov. 



Thallus atrofuscus filiformis, filis longissimis teretihus Isevis 

 non-lacunosis infra nonniliil conjunctim tortis, supra remote 

 divergenti-raraosis Apothecia non visa. C. K., 8-4-84. 



Thallns filiform, dark-brown, nearly black, tlie thread-like 

 branches tortnosely anastomosing in the lower part, the ultimate 

 branches divergent, all terete not lacunose. Hab. Taylor's 

 Range (Bailey.) Nerang Creek, very fine (H. Schneider). 



Dr. C. Knight remarks that the jDresent species greatly re- 

 sembles A. Fremontii, Tuck, being as dark in colour and as much 

 elongated but more remotely branched and quite terete, the 

 Queensland specimens were not in fruit, but Alectorise are 

 rarely fertile.
