Hookeriales are mosses characterized by their delicate, intricate structure, typically forming dense mats in moist, shaded environments. These plants possess a high moisture requirement and display a preference for acidic substrates, often found carpeting the forest floor or draping over rocks. The slender, flexible stems and small, spirally arranged leaves are significant for their ability to thrive in low-light conditions, making hookeriales a vital component of their ecosystems.
