Resumo

Taxonomic and phylogenetic studies of volvate Macrolepiota specimens collected from Atlantic Forest in Northeast and Southeast Brazil are presented based on morphological and molecular (nrITS) data. Macrolepiota dunensis and M. sabulosa var. velistellaris are proposed as new taxa, and additional observations are presented about M. pulchella, a species previously known from Brazil. Macrolepiota dunensis and M. pulchella clustered in the clade corresponding to M. sect. Volvatae. Macrolepiota sabulosa var. velistellaris was placed together with non-volvate M. sabulosa var. sabulosa, close to another volvate taxon (M. rhodosperma var. velicopia), and together with species classified in M. sect. Macrolepiota. Our phylogenetic results provide additional evidence that the volva, which is not restricted to members of M. sect. Volvatae, evolved more than once in the genus. (AU)
