Biodiv. [online]. 2015, vol.86, n.3, pp.565-568. ISSN 2007-8706.  https://doi.org/10.1016/j.rmb.2015.05.004.

Marasmiellus volvatus is a small but striking species which was found only few times in the world. 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.
