About Ripartitella brasiliensis (Speg.) Singer
Ripartitella brasiliensis, commonly called the carnival cap, is a fungal species belonging to the family Agaricaceae. It was first published as a new species to science by Carlos Luigi Spegazzini in 1889. The cap of this fungus ranges from 1 to 4 centimetres (1⁄2 to 1+1⁄2 inches) wide, and its white surface is mostly covered by scales. Its stem measures 2 to 7 cm (3⁄4 to 2+3⁄4 in) long and 2 to 6 millimetres (1⁄8 to 1⁄4 in) thick. This fungus has whitish flesh and produces a white spore print. It is distributed in North America (near the Gulf Coast, where it occurs from May to November), Central America, South America, Africa, and the Bonin Islands of the western Pacific Ocean. It produces fruiting bodies in clusters on decaying hardwood tree wood, particularly that of oak.
