New records of earthstar fungi (Basidiomycota) for different physiognomies of the Cerrado biome, Brazil.

In the present study, six new records of fungi of the genus Geastrum Pers. are described in four different physiognomies of the Cerrado stricto sensu: Geastrum fimbriatum, G. lageniforme, G. morganiii, and G. hirsutum are the first records for the Brazilian Cerrado, being collected, respectively, in Typical Cerrado, Rupestrian Cerrado, Sparse Cerrado and Dense Cerrado. The specimen described as G. aff. rusticum is also the first record for the biome and was founded in Typical Cerrado. G. triplex is the second record for the Brazilian Cerrado and the first for the state of Bahia, found in physiognomies of Dense Cerrado. The taxa described present plates with photographs and micrographs for each species and a map for the collection locations. [ABSTRACT FROM AUTHOR]
