On legumes of Bossiaea heterofliylla, Vent.; September 1896; 

 National Park, near Sydney (Maiden). 



This species has already been described on Bossiaea cinerea, 

 R.Br., from Tasmania and Victoria (Proc. Roy. Soc. Vic. vii. N.S. 

 21, 1894), but is new for New South Wales. It was also found 

 on legumes of Bossiaea rhombi/olia, Sieber, sent from Richmond, 

 N.S.W., in November by Mr. Musson.

(Plate i. figs. 1-3.) 



Forming black, soot-like patches on both surfaces of leaves, 

 distinct or confluent, variable in size and shape, somewhat 

 orbicular, commonly | inch, but may unite into much larger 

 masses. Hyphce dark brown, thick-walled, septate, nodulose, 

 branched, branches upright and rigid, 1\^ broad. PerithecAa 

 depressed-globose, dark brown, rough, with a few adherent fibrils, 

 200-380 /i diameter. Asct clavate-obovate, subsessile, apex 

 rounded, 8-spored, 35-40 x 22-24^. Sporidia at tirst colourless, 

 then green, finally brown, 2-3 rowed, elliptic, uniseptate, slightly 

 constricted, upper division usually slightly broader than lower, 

 22x9^. 



On leaves of Hakea dactyloides, Cav. ; September ; National 

 Park, near Sydney (Maiden). 



With potassium-iodide-iodine solution the protoplasm of the 

 ascus before the spores are formed and even up to the time when 

 they assume the brown colour, is coloured bright' yellow, 

 while the rest of the contents is of a pale bluish tint. The sub- 

 hymenial tissue is also coloured yellow, but the accompanying 

 material is all pale blue. 



Tt approaches A. Baileyi, Berk, k Br., but there the patches 

 are reddish-brown and the sporidia are 37 /n long. 



The old genus Aster ina is now split up into several, according 

 to the septation and colouration of the sporidia, but by those who
