Amorphothecaceae

The Amorphothecaceae family encompasses a group of ascomycetous fungi that serve as causative agents for various pathological conditions in agricultural and forest crops. The most notable representative, Amorphotheca resinae, represents a significant concern not only for botanical health but also for industrial logistics and product storage.

The type of disease caused by this family is classified as a mycosis. The pathogens actively develop within plant tissues, leading to the decomposition of organic matter and the destruction of cellular structures. While often acting as saprotrophs, they can transition to a parasitic lifecycle under favorable conditions, compromising the immunity of weakened plants.

These fungi affect a wide range of woody species and can be found on cultivated plants that have sustained mechanical damage. A specific characteristic is their ability to develop on substrates containing hydrocarbons, which poses a substantial risk during the storage of plant products and timber in high-humidity environments.

Primary symptoms of infection include the appearance of fungal mats, tissue discoloration, premature wilting, and necrotic lesions. As the fungus matures on the surface of plant organs, it produces spore masses that are easily dispersed by wind, water, or agricultural tools to healthy crops.

The development of the pathogen is driven by high air and soil humidity, as well as improper agronomic practices. The economic impact involves reduced crop productivity, diminished quality of harvested produce, and the risk of seedling loss. Effective control and prevention require crop rotation, thorough disinfection of storage facilities, regular sanitary pruning, and the use of fungicides upon the first detection of symptoms.
