40. LARGE-SPORED PHYLLOSTICTA. 
(Phyllosticta longispora , n.sp.) 
Tip of green leaf withered for fully half-an-inch, and spot at 
lower margin, greyish, elliptical, about £-inch with margin raised, 
and brownish on upper surface, but less distinct on under surface. 
Perithecia scattered, immersed, dark-brown, globular, 170^. in 
diameter, darker and thicker surrounding mouth which is about 
40/,u diameter. 
Sporules hyalrne, elongated-elliptic, with finely granular 
contents, average 10-13 X 4—4^/i. 
On green leaves of Orange. - December, 1898. Armadale, 
near Melbourne. 
The tissue of the leaf is destroyed, leaving only the membrane 
of the upper epidermis which finally disappears leaving a hole. 
Not common. The size of the spore distinguishes it at once 
from other Citrus species of Phyllosticta. (Figs. 77, 78.) 
41. SCAB-PRODUCING PHYLLOSTICTA. 
(Phyllosticta scabiosa , n. sp.) 
Minute, black, punctiform, slightly erumpent pustules on scabs 
on Lemon leaf. 
Perithecia scattered, membranaceous, delicate, flattened sub- 
globose, with minute apical pore, about 90 x 80/x. 
Sporules hyaline, elliptical, 5J-6|r X 2p. 
On “scabs” on Lemon leaf. January. Palmwood, Queens¬ 
land (Tryou). 
On similar scabs, Ramularia scabiosa was found, which is very 
probably only a conidial stage of this fungus. 
This species approaches l\ disciformis (Penz.), but the sporules 
are narrower and hardly elliptical, and the “scabby” spots do not 
occur with the latter. 
It probably occurs wherever R. scabiosa is found, although I 
have only bad an opportunity of examining it on a Lemon leaf. 
(Figs. 79, 80.) 
42. WITHERING PIIOMA. 
(Phoma flaccida , n. sp.) 
Minute, black, gregarious, immersed, punctiform pustules on 
withered tip of Orange leaf, most numerous on upper surface. 
Perithecia dark-brown, depressed globose, 170p. diameter, with 
elliptical papillate mouth, 45 X 32^,
