7. P. lampas, Berk. Victoria, West Australia, Tasmania; on 



languid but not dead stems of Grevillea. 



8. P. nidiformis, Berk. West Australia; on the ground. 



9. P. noctilucens, Lev. Manilla; on tree stems. 



10. P. olearius, Dec. S. and S.E. Europe; among roots of Olive 



trees. 



11. P. phosphoreus, Berk. Tasmania; on roots of trees. 



12. P. promeiheus, B. & C. Hong Kong; on dead wood. 



13. Collybia cirrhata, Pers. Germany, Britain. 



14. C. longipes, Bull. Germany, Britain, Victoria, Queensland. 



15. C. tuberosa, Bull. Germany, Britain, Queensland. 



16. Fomes annosus, Fr. Europe, America, Queensland. 



17. Polyporus grammocephalus, var. emerici. Queensland, on 



trunks; New Guinea. 



18. P. sulphureus, Fr. Europe, Asia, Africa, America, Queens- 



land, Tasmania. 



19. Corticium coeruleum, Fr. New South Wales, Queensland, 



Britain; said to be phosphorescent. 



20. Xylaria hypoxylon, Grev. Europe, Australia; common. 



21. X. polymorpha, Grev. Europe, Australia; common. 



In the Honey Agaric (A. mellea) and the species of Xylaria it 

 is only the mycelial threads which are phosphorescent, and the 

 brilliant luminous appearance often seen in mines is due to the 

 so-called rhizomorphs of the same or similar fungi. It is curious 

 to note that the fructification which arises from these mycelial 

 threads and is the perfectly developed form should not exhibit 

 luminosity. 



Tulasne,* writing in 1848, remarks that four species only of 

 luminous Agarics appear at present to be known, viz., Pleurotus 

 gardneri, H. igneus, P. olearius, a,nd P. noctilucens, Lev., whereas 

 at least twenty-one are now known and probabty several are 

 unrecorded for Australia.
