Appalachian rhizomnium moss
Appalachian rhizomnium moss is a type of moss found in moist, forested regions of the Appalachian Mountains. It is characterized by its dark green, plushy leaves that form dense mats across the forest floor, offering a sponge-like texture. The leaves are large for a moss, visibly ribbed, and typically exhibit a slightly curved or tongue-shaped appearance. Appalachian rhizomnium moss thrives in shaded, humid conditions, often near streams, where its presence can indicate a healthy woodland ecosystem.
