Taxonomy of Geastrum species in the neotropics has been subject to divergent opinions among specialists. In our study, type collections were reassessed and compared with recent collections in order to delimit species in Geastrum, sect. Myceliostroma, subsect. Epigaea. A thorough review of morphologic features combined with barcode and phylogenetic analyses (ITS and LSU nrDNA) revealed six new species (G. neoamericanum, G. rubellum, G. brunneocapillatum, G. baculicrystallum, G. rubropusillum and G. courtecuissei). In additon, the presence of hairs on the exoperidium, a commonly used feature to diagnose Geastrum species, proved to be ineffective because it is a derived character within subsect. Epigaea.
热带地区 Geastrum 物种的分类一直是专家们意见分歧的主题。在我们的研究中，我们重新评估了模式标本，并将其与最近的采集标本进行了比较，以便对 Geastrum，sect. Myceliostroma，subsect. Epigaea 中的物种进行界定。对形态特征的全面回顾结合了条码和系统发育分析（ITS 和 LSU nrDNA），揭示了六个新物种（G. neoamericanum、G. rubellum、G. brunneocapillatum、G. baculicrystallum、G. rubropusillum 和 G. courtecuissei）。此外，外菌盖有毛发，这是通常用于诊断 Geastrum 物种的特征，但事实证明它是 subsect. Epigaea 中一个衍生的特征，因此效果不佳。
