李树流胶病为福州地区李树发生普遍而严重的病害。研究证实：其病原为葡萄座腔菌（Ｂｏｔｒｙｏｓｐｈａｅｒｉａｄｏｔｈｉｄｅａ（Ｍｏｕｇ．ｅｘＦｒ．）ＣｅｓｅｔｄｅＮｏｔ），其无性阶段为壳梭孢菌（Ｆａｓｉｃｏｃｕｍｓｐ．）。病菌生长发育的最适条件是：菌丝在ＰＤＡ培养基上生长最快，最适ｐＨ值为６～７，光照可促进病菌菌丝体产生分生孢子
Li Shuyu meningitis is a common and serious disease in Fuzhou Li Shu. The research confirmed that the pathogen is Botryosphaeriadothidea (Moug. Ex. Fr.) CesetdeNot, and the asexual stage is Fasicocum sp. The optimum conditions for the growth and development of the bacteria are: mycelium grows fastest in PDA medium, the optimum pH is 6 ~ 7, light can promote the mycelium of the bacteria to produce conidia
