ordinary colourless and coloured hypliae, together with glomeruli, 

 and pycnidia (principally pycnidia), were in great abundance, 

 and seemed to be the prevailing form. There were also immature 

 forms of perithecia, but not as yet in great quantity. The 

 pycnidia varied in colour from leek-green when unopened to 

 yellowish-brown when opened, and the specimen figured (fig. 28) 

 was 526 X 122 fj.. The pycnospores were generally pale green in 

 colour, but sometimes brownish, and the average size was 19 x 8/x. 

 (figs. 26-30). 



Other Victorian Specimens. — A few other specimens were 

 obtained from Brighton and Elsternwick, suburbs of Melbourne. 



The Brighton specimens were particularly rich in cerato- 

 pycnidia and the antennaria (figs. 31-35), while the Elsternwick 

 specimens showed abundance of pycnidia (figs. 36-37). 



South Australian Specimen. 



An orange-leaf was forwarded by Mr. Quinn, Inspector under 

 the Vine and Fruit Diseases Act, with the " Sooty Mould " upon 

 it, but not very largely developed. 



There were the colourless and coloured hyphpe, gonidia and 

 gemm;ie and abundance of glomeruli. The colourless hyphaj 

 were septate, branched, with moniliform or elongated joints, and 

 averaging 3 1-4| /x broad. 



The brown hyphse were septate, sparingly branched, and varied 

 in breadth from 4^-71 /x. 



The gonidia were similarly coloured and usually simple. 



The gemmttt were either clusters of dark brown cells or the 

 green mulberry masses derived from the glomerules. None of 

 the colourless quadrate bodies were met with. 



The glomeruli were usuall}^ of a yellowish-green to pale green 

 colour, and either isolated or in group. 



The presence of brown gemmse and glomeruli was the pre- 

 dominating feature (figs 38-39). 



New South Wales Specimens. 



The specimens sent through the courtesy of Mr. Maiden, Govt. 

 Botanist, from trees in the Botanic Gardens, Sydney, were badly
