PSEUDOPEZIZA CASUABINAE. 8p. Nov. 



L. Eodway, Gov. Botanist. 



(Read 9th August, Issued separately 20th November, 1915.) 



Subcutaneous but soon bursting through the epidermis 

 and forming a small cushion bearing numerous conidia 

 ■(Grloeosporium). Subsequently the pulvinus expanding, asci 

 are formed, and the formation of conidia ceases. 



Mature pulvinus oblong 0*5 - 1 mm. in long diameter, 

 dark red-brown, of a tough fleshy consistency. Conidia 

 hyaline, broadly oblong. Asci cvlmdric, 8 spored, spores 

 broadly oblong with very obtuse ends, hyaline 17 x 8 m- 

 Paraphyses filiform. 



On ultimate branchlets of Casuarinadistyla, Vent. Above 

 Waterworks, Hobart. 



The conidial stage is found in Spring and early Summer, 

 the ascigerous form in Winter. It appears to exercise 

 very little injurious effect upon the host. The branchlets 

 yellowing and falling earlier in the affected instances.
