On languishing or dead twigs of Orange. September, 1898 to 
July, 1899. Armadale, near Melbourne. Rare in spring (Sep¬ 
tember), but more plentiful in winter (July). 
The minute rust-like burst pustules were seated on the bark of 
the Orange-tree at the base of a dying twig, and adjoining fresh 
green wood. The eortox was still green beneath the ruptured 
pidermis, and various other fungi were associated with it, such as 
Phoma omnivora (McAlp.). (Fig. 73.) 
38. GRANULAR EPICOCCUM. 
(Epicoccum granulatum , Penz.) 
Sporodochia minute, hemispherical, jet black, gregarious, may 
be continent, pulverulent, just visible to naked eye. 
Stroma hemispherical, rich ruddy brown. 
Conidia olivaceous, with brownish tinge, sphacroidal, not 
pedicillate, many-celled and meshes of network slightly raised on 
surface, punctate-granular 20-28p . diameter. 
On decayed portions of fading Lisbon Lemon leaves. May, 
1899. Burnley, near Melbourne. (Figs. 105, 106, 107.) 
39. CITRUS PHYLLOSTICTA. 
(Phyilosticta hesperidearum , Penz.) 
On dirty-grey or brown, irregular, often confluent, slightly 
raised patches on upper surface of leaf, and the same or ruddy- 
brown blister-like patches on under surface. 
Perithecia gregarious, slightly erampent, punctiform, black, 
but golden-brown by transmitted light, with relatively large 
mouth, depressed globose, of parenchymatous texture, membra¬ 
naceous, 100-180^, diameter, 
Sporules hyaline, cylindrical to elliptic, rounded at both ends, 
31 ,—ob x 2—2})f.i. 
On living Lemon leaf. February, 1899. Doncaster, near 
Melbourne. 
On living Orange leaf. Juno, 1899. Armadale, near Mel¬ 
bourne. 
Plcospora herbarum (Rab.) appeared on the disrupted tissue in 
one case, and the leaf was affected with Sooty Mould in another. 
Larger or smaller patches occur on the leaf, sometimes at the 
margin and sometimes adjoining midrib. The fungus gradually 
breaks down the tissue until nothing is left but the veins, and 
these finally drop out leaving a large hole, or the margin is worn 
away. (Figs. 74, 7o, 76.)
