Amyloporia sinuosa is a crust-like fungus that grows on decaying hardwood logs and stumps. In East and Central Texas, it has been found to fruit throughout the year, with a preference for moist environments. The fungus produces resupinate to effused-reflexed basidiocarps with wavy or sinuous margins, and its pore surface is white to cream-colored. Microscopic features include cylindrical to slightly tapering basidiospores measuring 4-6 μm in length. It is a relatively rare species in the region, often associated with oak and other deciduous tree species.
