Extract from Wikipedia article: Ripartitella brasiliensis is a species of fungus in the family Agaricaceae. It was originally described as new to science by Carlos Luigi Spegazzini in 1889. The fungus is found in the southwestern United States and Mexico, Central and South America, Africa, and the Bonin Islands of the western Pacific ocean. It fruits in clusters on the decaying wood of hardwood trees, especially oak.
Ripartitella brasiliensis is a species of fungus in the family Agaricaceae. It has a small to medium-sized cap that ranges from 1-4 cm in diameter, typically bell-shaped to convex, and often has a wavy or lobed margin. The cap surface is usually smooth, dry, and colored reddish-brown to brown. The gills are free from the stipe, crowded, and pinkish-brown to brown. The stipe is slender, cylindrical, and typically shorter than the cap diameter. In East and Central Texas, Ripartitella brasiliensis has been found growing in association with deciduous trees, particularly oak and maple, in a variety of habitats including forests, woodlands, and urban areas. Fruitings often occur from spring to fall, typically in areas with rich soil and abundant organic matter.
