👉 Metamelanea is a type of fungus that produces a complex, multi-layered structure known as a metamorphic layer. This layer can be found in various environments such as soil, rocks, and even in some aquatic organisms like plankton or bacteria. The metamorphic layer serves several functions: it helps to protect the fungus from external factors, provides structural support for the fungus, and may also aid in nutrient cycling within the ecosystem.
