👉 Planihylaeus is a genus of fungi in the family Sclerotiumsidae, known for their distinctive spores called planihylae. These spores are typically spherical or egg-shaped and are often associated with fungal growth rings on the surface of a fungus's hyphae (fungal hyphae). The term "planihylaeus" refers to the spore-like structures they contain, which are crucial for their survival in the environment.
