👉 In botany, a propodium is a structure or organ that forms on the surface of an alveolus (a small air sac) in some types of plants. It's often used to describe a specific type of organ found in certain species of mushrooms. Propodiums are characterized by their thin, rounded, and slender appearance and can also be found on other plant structures like the stipe of a mushroom or the stem of a fern.
