196 Aecidium Genticwaccae, Compositae. 



On leaves of Plnntagn vnria R. Br. 



Victoria Murramurrangbong Ranges, Nov., 1902 (Robinson). 



Mt. Black wood, March, 1905 (Cyril Brittlebank). 

 New South Wales Guntawang, near Mudgee (Hamilton). 

 Tasmania Knocklofty, Oct., 1895 (Rodway 1 ). 



This species is given as A. plantaginis Ces., in Cooke's Handbook of 

 Australian Fungi, but there are no spots on the leaves, and the spores are 

 echinulate not tuberculate, as well as considerably larger. 



The Victorian specimens were rare, and the fungus was much overrun by 

 Darlucafilum Cast.

I. Aecidia on upper surface of leaf, gregarious, disposed without order 

 on rounded spots, or in concentric zones ; pseudoperidia scutelliform, 

 margin scarcely prominent, entire, or irregularly laciniate. 



Aecidiospores orange-yellow, angular, delicately warted, 12-20

On Limnanthemum indicum Thw. 



Queensland Near Brisbane, 1884 (Bailey 4 ). 



This aecidium was first found on the leaves of Limnanthemum nymphoides 

 Hoff. and Link and its connexion with Puccinia scirpi DC., was first sug- 

 gested by Chodat 1 . Then Bubak 1 , by means of cultures, proved the 

 connexion, but until the teleuto stage is found in Australia only the 

 aecidium stage will be given.
