Excluded or Doubtful Species. 207 



On leaves, twigs, and legumes of Cassia sp. 



Queensland Gladfield (Gwyther) (Bailey 13 ). 



In the original description, the spores are given as smooth, and 12-14 x 

 S-10 (.(, but on examining material kindly supplied by Mr. Bailey, of 

 Brisbane, tkey were found to be as above.

CHENOPODIACEAE. 



JRhayodia. 



160. Uredo rhagodiae Cke and Mass. 



Cooke and Massee, Grev. XV., p. 99 (1887). 

 Cooke, Handb. Austr. Fung., p. 343 (1892). 

 Sacc. Syll. VII., p. 859 (1888). 



II. Sori hypophyllous, scattered, globose, ruddy-brown, a long time 

 covered, at length torn and girt by the remains of the epidermis, 

 up to 1 mm. diam. 



Uredospores yellowish, ellipsoid, echinulate, with four or more 

 scattered germ-pores on one face, 24-30 x 17-22 p. 

 On leaves of Rhagodia billardieri R. Br. 



Victoria Botanic Gardens, Melbourne, June, 1886 (Watts). 

 Sandringham, April, 1905 (Robinson). 



Cooke and Massee gave measurements of spores as 20 x 15 p from 

 Watts' specimen from Botanical Gardens, Melbourne. I have been able to 

 examine part of that same material returned by Cooke and Massee to the 

 National Herbarium and find the spores to measure 24-30 x 17-22 p. The 

 rust is fairly abundant along the eastern shores of Port Phillip, and in fresh 

 material examined the spores have the same measurements, roughly about 

 27 x 20 p. 



Darluca filum Cast, is often found on the sori.

EXCLUDED OR DOUBTFUL SPECIES. 



When one considers that specimens of the various Rusts have hitherto 

 been mostly sent to Britain or Germany for determination, it can readily be 

 understood that sometimes the material was in an imperfect condition or not 

 in the best possible state for proper examination. Hence in some cases the 

 species were wrongly determined, and there are several recorded in Cooke's 

 Handbook of Australian Fungi, which on further investigation must be 

 removed from the list of Australian species. Sometimes, although rarely, it 

 happened that the host-plant of the parasite was wrongly given, and then a 

 new species has been created which afterwards turned out to be a known one. 

 On these and other grounds the following are excluded : 



1. Uromyces amygdali Pass. Cooke determined this on Peach and 

 Almond leaves from Victoria, New South Wales, and Queensland, but when 

 complete specimens were examined it was found to be merely the uredo- 

 stage of Puccinia pruni Pers. 



2. Uromyces junci (Desm.) Wint. This species has not been found in 

 Australia, as it was wrongly determined at Kew Herbarium for Puccinia 



juncophila Cooke and Mass. 



3. Puccinia acetosae (Schum.) Koern. This rust was determined by 

 Cooke on a native species of Rumex, but on the examination of a specimen 

 in the National Herbarium, Melbourne, named in his own handwriting, it
