ADDITIONS TO THE LICHEN FLORA OF 

 QUEENSLAND, 



By John* Shirley, B.Sc. 

 (Read on the 10th February, 1888.) 



DlJRlKu the past year many additions have been made to the list 

 of Queensland Lichens, the determination of species having been 

 performed by that able Lichenologist, Dr. C. Knight, of New 

 Zealand. 



Among new species the Following are worthy of special 

 remark : — 



Calicium hyperellum v. validius C.K 



Platysma eriophyllum ... C.K. 



Ricasolia plurimseptata ... C.K. 



Pannaria flexuosa ... ... C.K. 



Lecanora Queensland ia? ... C.K. 



Thelotrema expansum ... C.K. 



Graphis Parmeliarum ... C.K. 



These were, with two exceptions, collected for the first time 

 by myself ; for Pannaria flexuosa, O.K., and Lecanora Queens- 

 landia?, C.K., we are indebted to Mr. Keys, a fellow-member of this 

 Society. Having received the names only from Dr. Knight, I have 

 made a microscopic examination of each plant, and supply the 

 following descriptions : — 



1. Calicium hyperellum v. valicNus. C.K.— Thallus 



pale yellowish, obscured by the dark colour of the dead wood below 

 very thinly leprose, spreading thinly round the apothecia, but in 

 distinct between them, showing as a netting with square meshes 

 under the microscope. 



Apothecia following the lines of the slightly fissured or decayed 

 wood ; shortly stipitate (*2-*4 mm), dark-brown. Stipes cylindrical : 

 apothecia cup-shaped, upper surface coated with a dusty mass of 

 ejected spores.
