 detailed structure of fungus. 



Not only the Formosan white egg plant but all other Japanese 

 varieties are susceptible to this disease and in one case 60 to 70 

 per cent, of the crop was lost. Inoculation tests proved that other 

 solanaceous plants are susceptible and such plants as tobacco, 

 tomato and even Irish potato were attacked. Among plants be- 

 longing to other families, figs, Areca Catechu, and Hibiscus escu- 

 lentum were counted as susceptible hosts, and in a lesser degree 

 Epiphyllum truncatum and Ricinus communis.

Epiphyllous, sometimes also hypophyllous, lichenous, spreading 

 over an area 2-5 mm. across, tightly coalescent ; hyphae fuligi- 

 nous, thick-walled, 8/x across, septate and sparsely furnished with 

 hyphopodia, oblong bodies with rounded end usually on a stalk 

 18-25 fx long. Pycnidia and perithecia grow on the mycelial 

 layer, both orbicular black bodies, mostly sessile, sometimes on 

 stalks 18-25 fi long ; pycnidia 63-95 /x, containing numerous pycno- 

 spores ; pycnospores pale-brown, ellipsoid to oblong, glabrous, 

 unicellate, bi-nucleate, 6-8 X 3^4 p', perithecia 1 32-180^ in 

 diameter, with numerous asci ; asci oblong-clavate, ovoid-oblong, 

 with short stipules, hyaline, 33-49 X 10-12 fi, containing 8 spores; 

 ascospores oblong to short clavate, septate at the middle, color- 

 less, blunt or obtuse at both ends, 9-13 X 3.5—5 fi.
