Battarrea is a genus of mushroom-producing fungi.

The genus used to be classified in the family Tulostomaceae[3] until molecular phylogenetics revealed its affinity to the Agaricaceae.

Species of Battarrea have a peridium (spore sac) that rests atop an elongated, hollow stipe with a surface that tends to become torn into fibrous scales.

Inside the peridium, the gleba consists of spherical, warted spores, and a capillitium of simple or branched hyphal threads that have spiral or angular thickenings.

The genus is named after Italian priest and naturalist Giovanni Antonio Battarra.
