Decaying plants is one of the most common places where N. sphaerica is found. Many studies around the world found N. sphaerica as a leaf pathogen. N. sphaerica was isolated from various plants displaying leaf spots. These reported cases reveal newly identified plant hosts for the pathogen N. sphaerica that have been validated through Koch's postulates. The fungus causes a progressively fatal leaf spot diseases of a range of plants including blueberry (Vaccinium corymbosum), licorice (Glycyrrhiza glabra), and Wisteria sinensis (Chinese Wisteria). Initial lesions resemble small red spots around 2-5 mm particularly near the tips and edges of leaves, eventually resulting in complete defoliation. The fungus also causes a blight disease of the commercial tea plant, Camellia sinensis. Symptoms of blight was observed in commercial tea estates in Darjeeling, India. The disease affected plants of all ages, being especially pronounced in younger plants. Fungal colonies displayed an initial white colour that eventually turned gray/brown. Based on these morphological characteristics, N. sphaerica was identified as the fungal pathogen. Inoculation of the pathogen using conidial suspension spray, and re-isolation of N. sphaerica satisfied Koch's postulates. rRNA sequence comparison of the ITS region confirmed N. sphaerica identity. Cases of leaf spot disease of kiwi fruit (Actinidia deliciosa) have been reported from orchards in Huangshan, Anhui Provence, China. Infected leaves browned and defoliated. Conidia morphology and culture properties suggested N. sphaerica as the etiological agent, later confirmed by Koch's postulates and ITS identification.
