虽然真菌Zygophiala wisconsin是苹果黑斑飞斑病（SBFS）复合体的重要组成部分，但很少有研究表明这种或其他SBFS物种的原位形态适应伴随着果实表皮蜡层的定域性。利用扫描电镜观察了蜡表面核样体的形成阶段，以及这些结构形成次生核样体的分枝。在菌核样体形成的成熟阶段，菌丝、分生孢子和这些体之间的分生孢子的基质坍塌，形成了飞斑菌丝型中典型物种菌落的独立集群。此外，还首次在蝇斑属植物中发现了原位分生孢子和次生分生孢子的形成。
Although the fungus Zygophiala wisconsinensis is a prominent component of the sooty blotch and flyspeck (SBFS) disease complex of apple, few studies have characterized in situ morphological adaptations of this or other SBFS species that accompany colonization of the epicuticular wax layer of fruit. Scanning electron microscope was used to monitor stages in the formation of sclerotium-like bodies on the wax surface, as well as ramifications from these structures to form secondary sclerotium-like bodies. At a mature stage in the formation of sclerotium-like bodies, the matrix of hyphae, conidiophores, and conidia between these bodies collapsed, resulting in formation of the independent clusters of typical colonies of species in the flyspeck mycelial type. Formation of conidiophores and secondary conidia in situ were also described for the first time for any flyspeck species.
