Physalospora abdita

Physalospora abdita is a species of fungus in the family Botryosphaeriaceae. It is a plant pathogen that affects a variety of crops and ornamental plants. The fungus is known for its ability to cause significant damage to the plants it infects, leading to reduced yields and quality.

Taxonomy

The genus Physalospora was first described by the mycologist Pier Andrea Saccardo in 1880. The species Physalospora abdita was later described by Hans Sydow and Paul Sydow in 1912. The species name abdita is derived from the Latin word for "hidden", referring to the inconspicuous nature of the fungus.

Description

Physalospora abdita is characterized by its small, black, spherical fruiting bodies that are typically less than 1 mm in diameter. The fungus produces spores that are elliptical in shape and dark brown in color. The spores are dispersed by wind and rain, and can survive in the soil for several years.

Pathogenicity

Physalospora abdita is a pathogen that can infect a wide range of plant species. The fungus enters the plant through wounds or natural openings, and then colonizes the plant tissues, causing necrosis and wilting. The symptoms of infection include leaf spots, wilting, and dieback. In severe cases, the fungus can cause the death of the plant.

Management

Management of Physalospora abdita involves a combination of cultural practices and chemical control. Cultural practices include the removal and destruction of infected plant material, and the avoidance of overhead irrigation which can spread the spores. Chemical control involves the use of fungicides that are effective against the fungus.
