Gappia

Gappia is a genus of fungi in the family Gnomoniaceae. These fungi are primarily known as plant pathogens, often causing diseases in trees and shrubs. They are typically found in temperate regions and are characterized by their small, dark, often spore-bearing structures. The life cycle of Gappia species often involves a saprophytic stage, where they decompose dead plant material, and a parasitic stage, where they infect living hosts. Symptoms of Gappia infection can vary depending on the host plant and the specific species of Gappia, but may include leaf spots, blights, cankers, and dieback. Accurate identification of Gappia species usually requires microscopic examination of their reproductive structures, such as their ascocarps and spores. Research into Gappia species is ongoing, focusing on understanding their pathogenicity, life cycles, and potential control methods for the diseases they cause.
