There is a disease of Mandarins, already referred to, caused by 
a Septoria S. glaucescens (Trabut), and known as “ Melanose/* 
although causing a greyish-green discoloration. Trabut kindly 
sent me a specimen of the disease, and it will be seen from the 
drawing of the sporules (Fig. 47) that they are distinct, being 
hyaline, straight or curved, cylindrical, and no septa observed, 
17-19 x (Figs. 45, 46, 47.) 
21. BACTERIOSIS OR SOFT ROT OF LEMONS. 
The Lemons were ripe and firm and usually on one side, or it 
may be on auy portion of the fruit, there appeared depressions. 
These depressions are discoloured, soft, and with a brownish mar¬ 
gin, of a circular or irregular shape, and varying in size from lialf- 
an-inch in diameter to half the circumference of the Lemon. 
At first the colour is rather bleached, then it may become 
brownish. The surface of the diseased patch is covered with a 
slimy slightly viscid moisture, containing innumerable bacteria. 
On ripe Lemons. September, 1898. Glen Holford, Stawell 
(Wetteuhall). 
The softening and discoloration of the skin may oxtend its 
entire depth to the juicy interior. 
The grower informs me that this disease was first noticed in 
1897, and, in reply to queries, that it first appears when the fruit 
is on the turn in colour, and that it comes out very strongly on 
stored Lemons and is favoured by moisture. It is not due to 
chafing on the spurs, because it appears where Lemons have no 
chance of being bruised in this way, still, no doubt, where such 
chafing occurs would predispose that part to the disease. The 
grower also noticed that there are blotches on the young shoots 
similar to those on the fruit. 
Specimens have been submitted to Dr. Cherry of the Bacterio¬ 
logical Laboratory, University of Melbourne, and in due course 
will be investigated and reported upon.
