The rough scaled green gilled umbrella belongs to a genus in the umbrella mushroom family. These types of fungi usually grow in saprophytic environments and have a medium to large body size. The cap is usually a brown to light brown scale, with a diameter of up to 5-25 centimeters, and a hemispherical or flattened spherical shape. It gradually unfolds in the later stage, with a slightly raised center. When young, the epidermis is dark brown or light brown, and as it matures, it cracks open. The scales at the top are large and thick, appearing brownish purple. The stem is smooth. White or pale yellow, some species will turn green after maturity. White or cream colored, some species have spore marks that are even green. Usually, there are thick walled fungal spores with no or flat covered pores, and a mesh like structure inside the gills.
