• 中文摘要： 花生葉斑病菌在秋季花生病葉上可產生成熟之精子器及精子，但無子囊殼產生。冬季置於坪林山區之病葉則可產生發育中之子囊殼，但未能發現成熟之子囊胞子。人工培養誘導之嘗試均告失敗。文中討論臺灣花生葉斑病菌產生有性世代之可能性。
• 英文摘要： The purpose of this paper was to searchfor the perfect stages of Cercospora arachidicolaand C. personata, the leaf spot pathogens ofpeanut, in Taiwan. Mature spermogonia andspermatia were found on diseased leaves collec-ted from fields in late autumn. However, fullydeveloped perithecia and ascospores have neverbeen observed. All efforts to induce the formation of per-fect stages of these two fungi have failed,except for the diseased leaves placed in themountain area of Pin Lin during winter season,in which developing perithecia were detected. The possibilities of perfect stage formationof the two pathogens in Taiwan and their rolein disease occurrence were discussed.
