rounded at the tip, hyaline, 150-177// x 17-20//, accompanied by many 
thread-like paraphyses. Ascospores 8 in an ascus, clavate, hyaline to straw- 
colored, 11 - 17-septate, 50-64// x 6.5 - 7.5//. 
Hab. On Parlatoria zizyphi (Lucas) Sign, infesting Citrus nobilis 
Lour. 
Formosa: Tennaiho, Taihoku. (Y. Fujikuro, March 11, 1911). 
Remarks. The distinguishing characteristic of the present species is 
the production of four conidia on the apical cell of the conidiophore, although 
there are occasionally cases with three or five. From the previous species, it 
is easily distinguished also by the shape of the conidia as well as by the size 
and shape of asci and ascospores, and also by the shape of perithecia. 
This fungus, although not so common as Ophionedria coccicola , is still 
commonly found on the scale-insects infesting the orange-trees in Formosa, 
often associated with the latter on the same leaf. 
By comparing it with the other species of this genus already described, 
wo have not been able to find one which corresponds exactly with our plant. 
Moreover, Ophionedria coccieola has been so far the only species of the 
genus known to infect the scale-insects. The other species may upon fur- 
ther investigations be found to be entomophilous as in our present case.
