Descrizione generale

Calcium oxalate (CaC2O4) belongs to the class of oxalates that are associated with soils and lead litter. It forms crystals that are free-living, pathogenic, and plant symbiotic fungi. It is formed by the re-precipitation of calcium as the oxalate.[1]

The basidiomycete fungus Moniliophthora perniciosa is the causal agent of Witches' Broom Disease (WBD) in cacao (Theobroma cacao). It is a hemibiotrophic pathogen that colonizes the apoplast of cacao's meristematic tissues as a biotrophic pathogen, switching to a saprotrophic lifestyle
