In order to elucidate the life history, especially the relationship between periods of spore dispersal and infection, of this fungus as endophyte of pine needles, the seasonal changes in the numbers of colonies on living (current-, 1-year-old and 2-year-old) and dead (attached and fallen) needles and the numbers of ascocarps on fallen needles of Japanese black pine in Sakurajima, Kagoshima Pref. were examined for 3 years. The numbers of colonies in dead needles showed slow changes, while those in living needles changed drastically between sampling months. In dead needles, the patterns of changes in the numbers of colonies were similar among the 3 years and between attached and fallen needles, while those in living needles were dissimilar among the 3 years and among needle ages. Numbers of mature ascocarps rapidly increased in June and decreased until summer, with a peak in late June, and kept low numbers in other seasons, all common for the 3 years. The numbers of immature ascocarps tended to decrease in the period when mature ascocarps increased. Thus, the period of spore dispersal was constantly concentrated in the period from June to August, but the rapid increase in the number of colonies in living needles irregularly occurred several times in a year, which shows that the periods of spore dispersal and infection were different.}, pages = {9--17}, title = {クロマツ生葉及び死葉におけるLophodermium pinastri のコロニー数及び子嚢盤数の季節変動}, volume = {42}, year = {2015}, yomi = {ハタ, クニヒコ and ハマダ, マサノブ and ヤスダ, ショウタ and トミナガ, ショウヘイ and ヒラタ, ミキ and ナカシマ, アヤカ and タナカ, タクヤ and ササキ, リョウジ and スギムラ, タカユキ and ヒラタ, リョウコ and ソネ, コウイチ} }
