64. COMMON MACROSPORIUM. 
CMacrosporium commune , Rabh.) 
On dead tips of twigs of Lisbon Lemon. September, 1898. 
South Australia. 
This species lias only hitherto been recorded for Queensland. 
65. HIDDEN FUSARIUM. 
( Fv&arium cryptum, n. sp.) 
Sporodochia very minute, pale red, but seldom distinctly seen. 
Hyphae hyaline, densely crowded, septate, constricted at septa, 
and often moniliform, sparingly branched, about 4p. broad. 
Conidia hyaline, slightly curved, blunt at both ends or at least 
at one end, 8-septate, average 19-22 x 3i—4^z. 
The sporodochium or sporo-bed is intermixed and to a certain 
extent overlaid by the same olivaceous fungus associated with 
Ascoctryta citricola , so that it simply appears to the naked eye as 
a dark irregular incrustation, 
. The conidia are 3-septate, occasionally Lseptate, fairly regular 
in size and projecting at the margin of the crust. On dead 
twigs of Lisbon Lemon. September, 1898. South Australia 
(Quinn). 
This is a very distinct species and does not agree with any of 
the recorded forms. The conidia are decidedly hyaline, very 
regular in size and shape, and never more than 3-septate. The 
specific name is given from the Fusarium being hidden by the 
olivaceous fungus. (Figs. 139, 140.) 
66. FLESH-COLOURED FUSARIUM. 
(Fusarium incarnatum, Desm.) 
Sporodochia diffuse, while to flesh-coloured. 
IIyph?e creeping, hyaline, septate, slender 2p. broad. 
Conidia produced at apex, colourless, fusiform to slightly fal¬ 
cate, bluntly pointed at both ends, generally 5-septate, but varying 
from 3-7 septate,- not constricted at septa, 40-,54 X 3-5/*., average 
45-49 X 4-4iju. On Lemon stems associated with Gibbcrella 
pulicaris. October, 1878. Ardmona, Victoria. July, 1899. Doib 
caster, near Melbourne. The Doncaster Lemon tree was dying 
from root-rot, aud a portion of the bark was destroyed on one side 
near the collar. (Fig. 141.)
