Abstract

Based on phylogenetic and morphological evidence, two new Lepiota sect. Lepiota species collected from southwestern China are described and illustrated, namely L. brunneophora and L. ochraceosquamea. Lepiota brunneophora has a pileus with yellowish-brown to brown squamules and striations, a reddish-brown to purplish-brown stipe covered with whitish, floccose squamules, and penguin-shaped basidiospores with a narrowed apex. Lepiota ochraceosquamea is characterized by dark yellowish-brown to light ochre squamules on the pileus, a whitish annulus, broadly fusiform basidiospores, and a trichodermal pileus covering composed of subcylindrical terminal elements, narrowing toward the apex and lacking basal short elements. A comprehensive phylogenetic framework within L. sect. Lepiota, including agaricoid and sequestrate species, is also provided.
