conidia were surrounded by hairs, which were united laterally 
by ladder connections and converged above. The conidia were 
hyaline, cylindric, slightly curved at the tips, six- to eight- 
septate, II0-120 Xx 6. 
The perithecia were clustered at the base of the conidial 
fructification, or scattered over the stroma which permeates the 
insect. They were globose, carmine-red, with a papillate, some- 
what paler ostiolum, 280» high and 230 diameter. The asci 
were eight-spored, 100 long. The spores were one-septate, 
hyaline, obtuse, not constricted, 17-20 x 7-8 p. 
Zimmermann compared his species to Nectria aurantucola B. 
and Br., from which he decided it differed in the colour of the 
perithecia, and the form of the conidial fructification, according 
to the figures given by Berkeley and Broome. His figure of the 
conidia shows spores of the Microcera type, not Pseudomucrocera. 
The only other record of this species appears to be that of 
Parkin, who assigned all the Ceylon Microcera forms to Nectria 
coccidophthora. Parkin’s measurements of asci and ascospores 
appear to be from specimens of Nectria coccidophthora, but his 
figures of synnemata and conidia (9, 10, 11) are Nectria aurantu- 
cola. Of Parkin’s specimens which are now available, that on 
Chionaspis biclavis on Tabernaemontana is Nectria coccidoph- 
thora, and probably that on A sterolecanium miliaris on Bamboo, 
while, from his description, that on Chionaspis biclavis on Tea 
was the same species. 
I have collections of what appears to be undoubtedly this 
species, on Chionaspis biclavis on Tea, Ceylon (two gatherings), 
on Chionaspis on an undetermined host plant, Ceylon (two 
gatherings), on Chionaspis biclavis on Tabernaemontana, Ceylon 
(Parkin’s specimen), on Chionaspis, on an undetermined host 
plant, India (E. J. Butler), and on Diaspis pentagona on Fla- 
courtia, Seychelles. It is noteworthy that, of the seven collec- 
tions six are on Chionaspis. 
The synnemata arise from a narrow, yellowish-white, loose, 
floccose stroma, or weft of hyphae, round the scale. They are 
orange-red or scarlet, paler towards the base, generally erect, 
usually clavate, expanding into an ovoid head. As a rule, they 
are not as stout as those of Nectria auranticola, being commonly 
about o-8 mm. high, with a stalk 0-15 mm. diameter, and a 
head 0-3 mm. diameter, but sometimes examples occur which 
attain a height of 1-4 mm., and a stalk diameter of 0-25 mm. 
The stalk is generally longitudinally fibrillose. When fresh, the 
synnemata are subtranslucent, and become hard and horny 
when dry. Specimens in which the stalk is almost wanting are 
not uncommon; these may be ovoid, or conical, about 0-4 mm. 
high, and 0-25 mm. diameter. As in Nectria aurantucola, the 
head is often curved to one side. The structure of the synne-
