Multilocus phylogeny and morphology reveal two new species of Lepiota (Agaricales, Verrucosporaceae) from southwestern China

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.
