Pachycladella zatoriensis is a crustose lichen belonging to the Graphidaceae family, characterized by a smooth to slightly granular thallus that adheres closely to its substrate, typically bark or occasionally rocks. Its small apothecia are lecanorine, often less than 1 mm in diameter, and typically dark brown or black in color. The mature ascospores are fusiform (spindle-shaped) and brown. Chemical analyses can reveal specific lichen substances present in this species. Pachycladella zatoriensis thrives in habitats with moderate humidity, commonly found in temperate to tropical regions. Its ecological role includes contributing to nutrient cycling in its environment, typical of lichens within its taxonomic family.
