Calonectria kyotensis

Calonectria kyotensis is a species of fungus in the family Nectriaceae. It is a plant pathogen that causes leaf spot disease in various plants, particularly in the Camellia genus. The species was first described in 2002 from specimens collected in Kyoto, Japan, which is reflected in its species name kyotensis.

Taxonomy

The species belongs to the genus Calonectria, which comprises over 150 species of fungi. Calonectria kyotensis is closely related to other species in the Calonectria genus, such as Calonectria morganii and Calonectria pseudonaviculata. The species was first described by Japanese mycologists in 2002.

Description

Calonectria kyotensis is characterized by its production of conidia, which are asexual spores. The conidia are typically cylindrical in shape and have a smooth surface. The fungus also produces perithecia, which are flask-shaped structures that contain the sexual spores. The perithecia are typically orange to red in color.

Distribution and habitat

Calonectria kyotensis is known from Japan, where it was first described. It has been found in the city of Kyoto, hence its species name kyotensis. The fungus is typically found on the leaves of plants in the Camellia genus.

Pathogenicity

Calonectria kyotensis is a plant pathogen that causes leaf spot disease in various plants. The disease is characterized by the presence of brown to black spots on the leaves. The fungus is particularly harmful to plants in the Camellia genus, including the economically important Camellia sinensis, which is used to produce tea.
