The total height of the sporodochium is up to 0.9mm. The 
base is ovoid or cylindric, 0-4 mm. high and 0-3 mm. diameter, 
with a conical tip, 0-5 mm. long. When moist, the whole fungus 
is subtranslucent, pinkish-red or coral-red, but when dry it 
appears whitish or pinkish, and minutely pruinose. 
The wall of the conical tip may be divided into teeth, as in 
the common form, but it is frequently continuous, except for 
a fissure extending along the whole length of the tip in the 
median line on the lower surface. Sometimes this fissure is 
narrow, rather broader above than below: in other cases, its 
sides are curved as shown in diagram 20, Plate V. The hyphae 
which form the wall of the tip are 4 » in diameter, equal, septate, 
and united by ladder connections. The wall is rather thick and 
fimbriate at the apex, and numerous long free hyphae, parallel, 
and similar to those which compose the wall occur on the 
inner side. 
In dry-weather forms, the sporodochium is uniformly conical 
without any evident constriction between the base and the tip. 
At other times, the sporodochium is constricted, and often 
curved. 
The conidiophores are short, 30-66, simple or branched. 
The conidia are arcuate, tapering uniformly to the ends, usually 
three-septate, a few five-septate. The septa are obscure, and 
apparently tardily developed. It is not uncommon to find the 
majority of the spores without septa. The aseptate tips are 
usually long, up to 20. Measurements of different collections 
have given the following dimensions: 70-86 x 4; 84-96 x 
3°5-4 4; 66-82 x 3-5-4 w; 38-64 x 3-4, some only 16-30 p (dry 
weather) ; 70-80 x 3°5-4 p. 
When the tip is filled with spores, the mass projects at the 
apex as a coral-red point. 
The specimen on Aonidia bullata mentioned by Parkin is 
similar to the above, but the sporodochia arise in the middle 
of the stroma, not at its edge. The spores are arcuate, three- 
septate, 70-80 x 4p. 
A curious abnormality of the form on Aonidia crenulata has 
been collected. It occurred on Memecylon with the normal form, 
the latter usually on the under surface of the leaf, and the 
abnormal form on the upper. No scale insects were visible on 
the upper side of the leaf, but it was covered with small, curved, 
hyaline, claw-like thorns, standing up obliquely. Each of these 
thorns arises from a broad, circular, hyaline, membranous, 
scarious patch up to 0-8 mm. diameter, which can readily be 
detached from the leaf. The thorn-like projection is about 
o-6 mm. high, strongly laterally compressed, and about 0-25 mm. 
broad. The convex edge is regular, but the lower edge, viewed
