Se caracteriza por sus basidiomas completamente blancos, píleo sulcado, láminas sin intervenosas y estípite con una volva en la base. La especie más próxima, M. coilobasis , se diferencia por la presencia de láminas con intervenosas y por los pleurocistidios y esporas de mayor tamaño. Esta es la primera cita de M. volvatus para Argentina, y es el registro más austral de la especie. En este trabajo se describe e ilustra a M. volvatus y se presenta una clave de identificación de la sección Candidi con las especies más próximas.]]></p></abstract>

It is characterized by its white basidiomata, sulcate pileus, lacking intervenous lamellae and stipe with a volva at the base. Marasmiellus coilobasis is a close species which differs from M. volvatus because of the presence of intervenous lamellae and larger pleurocystidia and spores. Marasmiellus volvatus is described and illustrated. Also an identification key to the species of section Candidi is presented. This is the first report of M. volvatus in Argentina and is the southernmost record reported of the species.]]></p></abstract>
