entirely green (P. viridispora, Cooke), or hyaline to very pale 
olivaceous (P. bresariolae , Sacc.), or pale yellow to hyaline 
(P. sphacrosperma , Karst.), or even pale fuliginous (P. syrinqica, 
Thuem.). P. sanguinolcnta, Rostr. is so named on account of* the 
blood-red spores, but there is no record of a Phoma with pink 
spores, and so I have named it as above. This just shows that, 
at the best, the colour of the spores is an artificial distinction, 
and must be treated as a matter of convenience. (Figs. 108, 
109.) 
45. FEDERATION DOTHIORELLA. 
(Dothiorella federata, n. sp.) 
Peritliecia in minute orumpent clusters (^—\ mm. long) on 
upper surface of leaf, globose, brown by transmitted light, of 
parenchymatous texture, with round or oval mouth, average 
ISOp. diam. 
Sporules hyaline, minute, almost cylindrical, rounded at both 
ends, 3i—4i X 1 i—2 p. 
On Lemon leaf also affected with “ Sooty Mould.'” February, 
1899. Doncaster, near Melbourne. 
Only a few erumpent clusters were seen at one spot, the raised 
epidermis surrounding them like a wall. It differs from D. 
placenta (Sacc.) found on the bark of the Orange, in which the 
sporules are 15 p. long, and from D. guar Silica (Speg.), found 
similarly, and in which the sporules are 24-2 6p. long. 
This species was named on 27th July, 1899—Federation day 
in Victoria. (Figs. 110, 111, 112.) 
46. DESTRUCTIVE PYRENOCI1AETA. 
(Pyrenochaeta destrucliva, n. sp.) 
Numerous distinct black pustules on orbicular to oval, grey 
patches, with ruddy brown margin. 
Perithecia on upper or under surface, mostly on upper, at first 
covered, then slightly erumpent, flattened globose or subglobose, 
dark-brown by transmitted light, membranaceous, brittle, with 
scattered spines, particularly round margin, opening by pore, 
240-300p. diam.; spines rigid, brown, tapering towards apex, 
often curved, 2-3-septate, 70-100 x 3-?>-4/.t. 
Sporules hyaline, cylindrical, continuous, rounded at both ends, 
bi-guttulato, 17-18 x 4 -5p. (Stained pale-yellow by Potassium- 
iodide-iodine). 
On leaf of Bitter Orange. July, 1896. Kew, near Melbourne. 
On leaf of Shaddock. September, 1892. University gardens, 
Melbourne.
