those of Fusarium epicoccum. This species is Fusarium, not 
Miucrocera, and it must be referred to Fusarium epicoccum. 
In 1909, Saccardo (Ann. Myce. vil, p. 437) described Microcera 
curta on scale insects on Tilia platyphylla, collected at Tamsel, 
Germany. The sporodochia were described as gregarious, de- 
pressed-globose, 0°5—0-75 mm. broad, reddish, rather compact, 
shining; and the conidia as cylindric, curved at either extremity 
but principally at the apex, obtuse, three-septate, not con- 
stricted, 20-25 x 4-5. I have examined the specimen, Sydow, 
Mycotheca Germanica, No. 849, in Herb. British Museum. The 
sporodochia are flattened-pulvinate, compact, and somewhat 
waxy-looking. The conidia are chiefly strongly and uniformly 
curved, a few being somewhat hookshaped. This species is 
indistinguishable from Fusarium eprcoccum. 
Patouillard, in Bull. Soc. Myc. France, xxvilI (1912), p. 142, 
described Microcera Tonduzit on an undetermined coccid on 
Ficus, San José, Costa Rica. The sporodochia were said to be 
fleshy, red, conical, about 200 » high, 120 » diameter, composed 
of close-packed, fuscous or rosy-red hyphae, 4-6 diameter. 
The conidia were curved, like a horse-shoe, with acute tips, 
hyaline, three-septate, scarcely or not constricted, I5—2I x 4p. 
On part of the type specimen kindly submitted to me by Prof. 
Patouillard, I was unable to distinguish sporodochia, but conidia 
were present. These conidia were falcate, or unequally, curved 
(hooked), or strongly and equally curved, the latter being the 
horse-shoe conidia of the original description; they were stout, 
three-septate, with obtuse tips, 15-17 x 4. These conidia are 
those of Fusarium epicoccum and I have little doubt that 
Microcera Tonduzii must be referred to that species. 
Sawada, in 1914, described Fusarium Aspidioti in a paper (in 
Japanese) on Some Remarkable Parasitic Fungi on Insects 
- found in Japan. The sporodochia were situated at the margin 
of the scale, and were circular, or long-elliptic, pulvinate, 
reddish, 0-2—0-8 mm. long, 0-2—0-3 mm. broad. The conidio- 
phores (Plate V, fig. 23) were much branched, the terminal 
branches being 21-28 x 2:5-3. The conidia were acrogenous, 
cylindric, strongly curved, rounded or obtusely pointed at the 
ends, hyaline, three-septate, 24-29 x 3°5-4:5 wu. It occurred on 
Aspidiotus perniciosus on Pyrus communis, Shizuoka, Honshu. 
I have not seen the type of Fusarium Aspidioti. On a leaf 
of Citrus nobilis from Taihoku, Formosa, April 25, Ig11 (ex 
Herb. Sapporo) there occurred a Fusarium in company with 
Podonectria coccicola, Pseudomicrocera Henningsii, and Micro- 
cera aurantticola, on the insects Parlatoria zizyphi Lucas and 
Lepidosaphes Gloverit Pack. It formed an effused, white, byssoid 
patch overrunning the scales. There was no pulvinate sporo-
