80. COCCUS FUSARIUM. 
(Fusarium epicoccum , n. sp.) 
Growing round margin and on top of Red Scale, Aspidiotus 
aurantii (Mask), pale brick-red, usually forming crescent-shaped 
effused masses, visible to naked eye. 
Hyphae hyaline, septate, branched, slender, 2\- broad. 
Conidia colourless, sickle-shaped, sometimes straight, acute at 
both ends, produced apically or from joints, 1-3-septate, 17-19 x 
2^/i. 
On Red Scale on branches of Mandarin Orange. August. 
Burnley, near Melbourne. 
In F. larvarum (Fckl.) the conidia are 24 u. long and twice as 
broad. 
Very few specimens of this species were obtained, so that its 
further history was not traced. (Figs. 177, 178, 179, 180.) 
81. COCCUS TUBERCLE. 
(.Microcera coccophila, Desm.) 
Minute, deep brick-rod tubercles, rounded or flattened and disc¬ 
like on surface, usually in small groups, visible to naked eye, hard 
and horny when dry, with short stem-like base. 
Hypha3 at base of couidiophoros hyaline, septate, closely com¬ 
pacted, 3-4//. broad. 
Couidiophores tufted, filiform, elongated (at least 280/x.) sep¬ 
tate, sometimes slightly constricted at septa, rose-pink in mass, 
with finely granular and often vacuolated couteuts, 4-4^/z. broad. 
Conidia same colour as couidiophores to hyaline, curved, elon¬ 
gated, usually blunter at free end than attached end, with finely 
granular, nucleated contents, variously septate, continuous up to 
8-septate, average 5-6, size from tip to tip of curve, and uot actual 
length, 75-103 x 5^-S^p. 
Parasitic on Red Scale of Orange and Shaddock, Aspidiotus 
coccineus (Gennad). July, August, &c. Botanic Gardens, 
Sydney, Now South Wales (Maiden). On Coccus infesting the 
Lemon. Queensland (Bailey). (Figs. 181, 182). 
82. ORANGE COCCUS TUBERCLE. 
(Microcera rectispora , Cooke and Mass.) 
Tufts rather sphaeroul, almost sessile, at first reddish, at length 
pallid. 
Conidia elongated-fusiform, acute at each end, 7-9 septate, 
straight, hyaline, 150-200 x 10^z. 
Couidiophores short, thin, furcate, hyaline.
