The Angsana tree, the host-plant, is grown as an avenue tree 
in several towns in the Malay Peninsula. As allied fungi cause 
early defoliation, the extension of the parasite should be che¢ked, 
which could be accomplished by collecting and burning the fallen, 
diseased leaves. If spraying be practicable, half strength Bordeaux 
mixture should be applied when the foliage is young, independent 
f the appearance of the disease, in those districts where it has 
previously existed, 
DEUTEROMYCETES. 
Diplodia Arecae, Massee (figs. 1-4). 
Stromata tuberculoso-subhemisphaerica, 3-4 mm. diametro, 
erumpentia ac subsuperficialia, aterrima ; perithecia densiuscule 
gregaria, atra, irreeulariter dehiscentia, contextu parenchymatico 
pellucido fuligineo. Sporulae ellipsoideae, utrinque obtusatae, 
rectac, l-septatae, hyalinae, dein atrofuseac, 28-35 x 15-17 pu. 
Goup Coast, Aburi; parasitic on the seed of Areca Catechu, L., 
A, I, Adams, 
The nuts, on arrival at Kew, appeared to be perfectly sound and 
free from disease, and were placed in a glass jar for exhibition 
purposes. After a period of some weeks, black pustules bursting 
through the testa were observed on some of the nuts, and in course 
of time, almost every nut became more or less thickly covered with 
prominent, black warts. In healthy seeds the endosperm is white, 
bnt in those that are infected it is converted into a blackish spongy 
mass. The endosperm is thoroughly permeated by the dark-coloured 
mycelium before the fruit of the fungus bursts through the testa. 
The appearance of the seed suggests that infection takes place at a 
very early stage of its development, probably through the stigma. 
Technically D. Arecae is very close to D. cacacicola, P. Hemn., 
as originally described, but at the present time so many apparently 
ifferent forms have been aggregated under the name D. cacaoicolu, 
that D. Arecae may possibly be included amongst such, and if so, it is 
very important that the fungus on Areca should be diligently sought 
out and destroyed by burning, otherwise there is the probability of 
its passing on to other host-plants of economic importance, as the 
species of Diplodia are not so restricted in their choice of a host as 
are some parasitic species of fungi 
Isaria Pattersonii, Masse (figs. 15-17). 
Stroma effusum, crustaceo-tomentellum, matricem totam externe 
atque interne ambiens, cinereum, ubique ramulos erectos multifidos 
emittens ; ramuli ex hyphis filiformibus densissime constipatis apice 
plus vel minus liberis efformati, Conidia in hypharum apicibus 
acrogena, numerosissima, globosa, hyalina, 2 u diametro.

‘rom analogy, this fungus must be considered as the conidial 
condition of .a species of Cordyceps.
