RESUMO

Abstract Three species of Volvariella from Northern Argentina are illustrated and described. Volvariella taylorii, known from the Yungas and the Paranaense Rain Forests; V. subxerophytica, known exclusively from the xerophytic forest from "chaqueña" region, and V. pusilla which was found in Chaco and Tucumán provinces. The two former species are characterized by having brownish-grayish volva and the fibrillose pileus, and the later by its whitish-grayish volva and the finely and delicately fibrillose surface of the pileus. Volvariella taylorii is recorded for the first time from Argentina and the area of distribution of V. subxerophytica is expanded towards the oriental area of the "chaqueña" region. It is important to mention that V. subxerophytica was only known by the type material and that in this work the original description is improved with data obtained from new specimens.
