85 
height and 0.3 mm. in diameter. Asci fasciculate, cylindrical-clavate, rounded 
at the apex, hyaline, 189-280// x 17-20 //. Paraphyses filiform, hyaline, 
of about the same length as asci. Ascospores 8 in au ascus, cylindrical- 
clavate, hyaline to straw-colored, 20 - 24-sept ate, 75 - 165// x 6-8 //. 
Hab. On Parlatoria zizyphi (Lucas) Sign., Aspidiotus ficus

Distrib. North and South America, West Indies, Japan, Java and 
South Africa. 
Remarks. The present species is rather common in Formosa on 
different scale-insects infesting the orange-leaves, but is not so common as 
Sphaerostilbe coccophila. With us, both the ascosporous and conidial stages 
are found. Their characters coincide very closely with the descriptions given 
by Ellis and Everhart (8), and also by Zimmermann (32). Only 
in the size of the asci, we see some difference. In our form, the length of 
the asci ranges from 225 to 280//, the average being about 256 // ; while the 
length given by Ellis and Everhart is 150-190//. The breadth, how- 
ever, is exactly the same in both cases. 
Ophionectria tetraspora Miyabe et Sawada, sp. now 
(PI. VII. fig. 17-22). 
Sporodochia globose to obovoid, grayish white, mostly 3-6 on a scale, 
0.3 -0.8 mm. in diameter. Conidiophores densely packed together, monili- 
form, bearing 3 — 5 mostly 4 conidia on the apical cell. Conidia become 
free connected together by the apical cell ; single conidium cylindrical slightly 
tapering toward the acute or obtuse tip, subelavately cylindrical, when half 
matured, hyaline, 12 - 20-septate, 105 - 190// x 7-9.5//. 
Perithecia cespitose, subglobose to obovoid, darkish brown, about 0.5 - 
0.6 mm. in height and 0.5 mm. in diameter. Asci fasciculate, clavate,
