Nectria foliicola
Nectria foliicola is a species of fungus in the family Nectriaceae. It is a plant pathogen that primarily affects leaves of various plant species.
Taxonomy[edit | edit source]
The species was first described in the scientific literature by the mycologist John S. Karling in 1934. It belongs to the genus Nectria, which comprises around 110 species of fungi. The species name foliicola is derived from Latin and means "leaf-dwelling", referring to the fungus's habitat.
Description[edit | edit source]
Nectria foliicola is characterized by its small, red perithecia, which are the fruiting bodies of the fungus. The perithecia are typically found on the underside of leaves. The ascospores, or sexual spores, are hyaline and typically have a filamentous shape.
Distribution and habitat[edit | edit source]
Nectria foliicola is found worldwide, particularly in temperate regions. It is a common inhabitant of leaf litter, where it contributes to the decomposition of organic matter. The fungus can also be found on living leaves, where it may cause leaf spots or other symptoms of disease.
Pathogenicity[edit | edit source]
As a plant pathogen, Nectria foliicola can cause significant damage to a variety of plant species. The fungus enters the plant through wounds or natural openings, such as stomata, and colonizes the leaf tissue. This can lead to the formation of leaf spots, necrosis, and premature leaf drop.
Management[edit | edit source]
Management of Nectria foliicola typically involves cultural practices, such as the removal of infected leaves and the maintenance of plant health. Fungicides may also be used in severe cases.
