Clathrus are known for their unique and often strikingly odd appearance. They usually produce a lattice-shaped, cage-like or net-like structure that can capture the viewer's attention. When mature, these fungi emit a strong, often unpleasant odor to attract flies and other insects, which help in dispersing their spores. Some species even have eye-catching, vibrant colors like red or orange, making them stand out in their natural habitats, often forest floors or decaying wood.
