重新研究了日本梨和中国梨的疮痂菌Venturia nashicola与欧洲梨疮痂菌V. pirina的关系。水梨V的子囊孢子比水梨V长、宽，分生孢子明显短于水梨V。培养的交配实验结果清楚地显示了物种之间的性隔离。梨病毒仅对日本梨和中国梨有致病性，梨病毒仅对欧洲梨有致病性。结果表明，水曲霉与水曲霉具有明显的区别。
The relationship of Venturia nashicola, the scab fungus of Japanese and Chinese pears, to the European pear scab fungus, V. pirina, was reexamined. Ascospores of V, pirina were longer and wider than those of V. nashicola and the conidia of V. nashicola significantly shorter than those of V. pirina. Results from mating experiments in culture clearly showed sexual isolation between the species. V. nashicola was only pathogenic on Japanese and Chinese pears and V. pirina was only pathogenic on European pear. It is concluded that V, nashicola is distinct from V. pirina.
