100-250 x 4p. The conidia were elongato-fusoid, falcate, multi- 
guttulate or obsoletely septate, with subacute tips, pinkish 
hyaline, 80-100 x 3°5—-4. I have not seen the type specimen, 
but from the description of the stroma and the conidia, this 
would appear to be Pseudomicrocera. 
C. Specimens on Aspidiotus articulatus on Coffee, Soto, West 
Africa. This collection was enumerated by Parkin. In general 
appearance, it resembles the Ceylon specimen on A spidiotus on 
Hevea. In some cases the scale is surrounded by a narrow stroma, 
with a fibrillose margin which may spread out over the leaf for 
a distance of two or three millimetres; in others, no stroma is 
visible, and the bases of the sporodochia are partly hidden by 
the scale. The sporodochia lie flat on the leaf, radiating in star 
fashion from the scale. Their bases are small, not exceeding 
o-2 mm. in height, but the white tip is well developed. The 
teeth are distinct down to the base; viewed from the lower 
surface, they may be widely separated or not. The conidia are 
of the usual type, arcuate, equally curved, with tapering points, 
three- to five-septate, readily collapsing, 92-134 x 3p. 
This form differs from the common Ceylon species, only in 
the greater length of its conidia. It may be known as var. 
longispora. 
D. Specimens on Aonidia, Ceylon. Specimens on Aonidia 
crenulata on Memecylon (Plate III, figs. 9, 10), and Aonidia 
bullata on Nothopegia Colebrookiana were described by Parkin. 
The former is common on a group of Memecylon edule in the 
Royal Botanic Gardens, Peradeniya; of the latter, I have only 
the specimens referred to by Parkin. 
On Aonidia crenulata, the fungus forms a narrow stroma, up 
to 0-25 mm. wide, either all round, or at one side of, the scale. 
This stroma is pinkish-red, thin, compact, with a whitish, 
fimbriate margin, and often radially grooved. It usually grows 
centripetally over the scale, as well as centrifugally over the 
leaf, but the centre of the scale is generally left exposed. The 
scale appears red, or scarlet, owing to the growth of the fungus 
beneath it, and the naked centre is more vividly coloured than 
the stroma. In wet weather, the stroma is coral red; when‘dry, 
it has a delicate covering of scattered, whitish hyphae. 
The sporodochium almost always arises at the inner edge of 
the stroma, so that it is perched on the top of the scale, as a 
rule. Also, it usually arises from the extreme edge, and is 
attached to the stroma, not over its whole base, but at one side, 
so that at first sight it appears to be disconnected from the 
stroma. Generally only one sporodochium is borne on each 
waar a there may be two. It is usually oblique, rarely hori- 
zontal.
