从墨西哥马扎尼约进口日本的香蕉腐烂果实中分离到7株镰刀菌。对分离菌株的形态特征进行了描述和图解，并测定了其对香蕉的致病性。形态学和分子系统发育分析表明，这些分离物归属于F。轮枝状然而，不断生产的分隔气生分生孢子链的香蕉分离物区分这些菌株从以前的描述这个物种。对分离株的形态学检查表明，它们与Wollenweber最初的F.串珠状变种减去。同时还研究了黑光灯对这些菌株产孢的影响。黑光灯能刺激香蕉各菌株产孢，并对分生孢子的长度有正效应。
Seven strains of Fusarium were isolated from rotten fruit of banana (Musa cavendishii) imported into Japan from Mazanillo, Colima, Mexico. Morphological features of the isolates were described and illustrated, and their pathogenicity to banana was determined. Morphological and molecular phylogenetic analyses revealed that these isolates were assignable to F. verticillioides. However, constant production of septate aerial conidia in chains by the banana isolates distinguished these strains from previous descriptions of this species. Morphological examination of the isolates revealed that they are consistent with Wollenweber's original concept of F. moniliforme var. minus. The effect of black-light illumination on conidial production by these isolates was also tested. Black light stimulated production of sporodochial conidia of all banana isolates and had a positive effect on conidial length.
