Macrocybe titans is an edible mushroom species native to Florida, Central America, and South America. It was first described under the name Tricholoma titans in 1980 by Howard E. Bigelow and J. W.

The cap measures 8 to 50 centimetres (3.1 to 20 inches) across, and rare specimens can reach up to 100 centimetres (40 inches) in diameter. The cap color is buff-ochre, with a darker center and greyish margins, and it fades to white as the mushroom ages. The gills are crowded, white to pale grey or pale brown, sinuate, and can grow up to 2 cm thick. The stem is cylindrical, stout, and white, reaching 6 to 15 centimetres (2.4 to 5.9 inches) in height and 1.5 to 4 centimetres (0.59 to 1.57 inches) across, with a swollen base that can be up to 12 centimetres (4.7 inches) in diameter. Rare specimens have stems that grow up to 38 centimetres (15 inches) high and 12.7 centimetres (5.0 inches) wide.
