FUNGUS- BLIGHTS OF QUEENSLAND. 399 



a species ot the same genus. R. hypoxanthum, B. and Br., 

 at times quite destroys the leaves of Cudrania javanensis in 

 North and South Queensland. Those persons, however, who 

 go into ecstasy over variegated foliage would probably con- 

 sider this fungus added a beauty to the Cudrania bushes. 



Septoria oleandrina, Sacc. — This fungus may at times 

 be seen on the Oleanders, but is not at all common. It is 

 found on the leaves of the same genus in Europe. 



SoROSPORiUM ERiACHNES, Thiim., was found on the in- 

 florescence of one of the Queensland species of Eriachne. 



Sph^rella dammars, B. and Br. — Found on young 

 plants of Agathis {dammara) rohusta, received from Fraser's 

 Island. S. destructiva, B. and Br. — During some 

 seasons this fungus is very injurious to the Lucerne crop, 

 more particularly on fields which have been many times cut, 

 or the land undrained. The presence of the blight is at once 

 known by the large number of flies it seems to attract, in 

 fact it was the flies which drew my attention to it in the first 

 instance about twelve years ago. S. rubiginosa, Cooke, was 

 found on leaves of Pittosporum ruhiginosum from the John- 

 stone River. S. smilacicola, Schw. which is met with in 

 North America on the foliage of Smilax, was also detected 

 on the plants of that genus and Dioscorea, near the Logan 

 River. Sph^ria (Depazea) litse^., B. and Br. — This 

 some years quite destroys the older foliage of Litsea dealhata. 

 S. (Subtecta) macrozami^, B. and Br. — The nuts of 

 Macromzamia Hopei at the Daintree Kiver are often nearly 

 covered by this fungus. 8. polyscia, B and Br., is also 

 frequently found disfiguring various kinds of gourds grown 

 for ornamental purposes. 



Sph^ropsis rosarum, C. and Eli, which in North 

 America is found on the branches of Rose-bushes, has been 

 met with at the Logan River in Queensland on the same 

 kind of plants. S. tricorynes, B. and Br., mfests plants 

 of Tricorynes anceps in Northern Queensland. 



Sph^rotheca pannosa. Lev. — This, the conidiophorus 

 condition of Oidium leucoconium, usually known as " The 

 Rose Blight," and which is found in all parts of the world 

 where. these plants are grown, attacks the Rose-bushes in 

 Queensland, and has a high time of it, for, so far, I have 

 never seen anything done to check its ravages. At the 

 present time (N ovember) most of the Roses about Brisbane 

 are covered by a thick veil of this blight, although, had the 

 sulphur-bellows been freely used upon the bushes at an earlier
