Abstract

The genus Cystolepiota, which belongs to the family Agaricaceae, is differentiated from the other genera of the family mainly because it has a white to cream print spore and the cortical layer of the pileus is constituted by spherical cells, usually organized in short to long chains, the pileus surface being strongly pulverulent in some species. This paper presents the study of 14 species of Cystolepiota, cited for Brazil and Tucumán, Argentina, which was based on herbarium specimens and literature available about the South American mycobiota. Seven species, namely C. albogilva Singer, C. amazonica Singer, C. marthae Singer, C. potassiovirens Singer, C. seminuda (Lasch) Bon, C. sistrata (Fr.) Singer ex Bon and Bellù and C. violaceogrisea (Rick) Singer, have been cited for Brazil. Five species, viz. C. australis Singer, C. adulterina (F.H. Møller) Bon, C. brunneotingens Sing, C. constricta Singer and C. rubra Singer, were cited only for Argentina. In addition, C. rosea Singer was cited for Argentina and Chile and C. luteifolia Singer was described from Peru. Illustrations of micro-morphological features are presented for these species and an artificial key for species identification, based on examined specimens and in the original description, is provided.

Keywords: Agaricomycetes, Agaricaceae, taxonomy, diversity.
