Helotiaceae is a family of fungi belonging to the order Helotiales. These fungi are primarily known for their cup-shaped fruiting bodies, which can be found on decaying wood, soil, or plant debris. They play an essential role in the ecosystem by breaking down organic matter and recycling nutrients. Members of the Helotiaceae family are often small and can be brightly colored, ranging from yellow to orange or even black. Some species are important in the study of fungal biology and ecology, while others may have potential applications in biotechnology or medicine.
