8. R. SCOPQLORUM, Ach. — On trunks of Armtcai-ia excelsa (A. 

 Cunn. in Heward). 



It is quite probable that this species may occur in Norfolk 

 Island, but it is questionable if those plants collected by A. 

 Cunningham on trunks of Araucaria are the true R. scopulorum 

 of Acharius, as they have never (so far as I can ascertain) been 

 found on other than maritime rocks.
