et E v.) B e r 1. et V o g 1. and 0. tetraspora sp. n. Of these, Sphaeroslilbe 
coccophila has the widest distribution, extending as far north as Hokkaido. 
Aschersonia marginata and Asch. SuzuJcii have also been found outside of the 
Island of Formosa; the former in Kagoshima, and the latter in Shizuoka 
and a few other places. 
Very little has been done concerning the researches on coccophilous fungi 
in Japan. In 1901, H. Nomura (18)* published the result of his study 
on the “scarlet-fungus disease” of scale-insects. As his paper was written in 
Japanese, it did not draw the attention of the scientific world, which it de- 
serves. He described there a new species of Nectria under the name of Nectria 
coccophila ,** which is parasitic on Aspidiotus perniciosus infesting pear-trees in 
Gifu, and also on Diaspis pentagona infesting mulberry-trees in Toyama. 
It appeared just one month previous to the appearance of Zimmermann’s 
paper (32) describing Nectria coccidophthora from Java. These two species, 
although closely related, are decidedly distinct, judging from the descriptions 
and figures given by the authors. 
According to Nomur a, the sporodochia of his species is not stilboid, 
but of irregular-shaped protuberances of the type of Tubercularia. By compar- 
ing it with the figures of Sphaeroslilbe coccophila by Rolfs (21), he came 
to the conclusion, that the Japanese and Florida forms seem to belong to one 
and the same species, and that both of them are quite distinct from the 
typical Sphaerostilbe coccophila of Tulasnes (29). Matsumura (16) and 
Shirai (27) mistook the author’s view, when they considered that No- 
rn u r a’s fungus should be called by the name of Nectria coccophila (T u 1.)

** Nectria coccophila Nomura (18). 
Sporodochia irregularly pulvinate, not stilboid, orange-red, on reddish stroma, some- 
times confluent. Conidia falcate, of Fusarium-type, 3-5-septate, reaching 100p. in length. 
Perithecia fliisk-shaped, bright red colored, appearing on the outer surface of a scale, 3-1 
in a group, 260-340[x in length and 240-320(1. in breadth. Asci fusiform, obtusely pointed 
at apex, 90-110(xx 8— 10p., 8-spored. Ascospores in one row, more or less inclined, light 
brown, 1-septate, slightly constricted at .septum, 15-20|xX 5-6|x. Stroma scarlet, sclerotioid 
in texture. 
Hab. On Aspidiotus perniciosus and Diaspis pentagona, infesting Pirus sinensis, and 
Morus alba respectively, in Honsiu, Japan.
