Armillaria mellea is commonly called the “Honey Mushroom” or the “Ringed Honey Mushroom.” A. mellea has a smooth and sticky, but sometimes dry cap. It is 1-4 inches wide and the color ranges from yellow to a yellow-rusty-brown. The cap may have stiff black scaly hairs. The gills are off-white and stain yellow to red; attached or slightly descending. The stalk is 2-6 inches long and 1/4-3/4 inches thick. It is white, turning yellowish to yellow-brown with age; has a thick annulus that is white to yellow, changing colors with the stalk as it ages. Stalks often fused at the base, coming to points. The white rhizomorphs are long and flattened. There are no clamps found at the base of the basidia. Spore print is white to cream. Spores are 8-12 × 6-7 micrometers; smooth, elliptic to ovoid, and inamyloid.
