Abstract

TRIERVEILER-PEREIRA, Larissa; CALONGE, Francisco de Diego  and  BASEIA, Iuri Goulart. New distributional data on Geastrum (Geastraceae, Basidiomycota) from Brazil. Acta Bot. Bras. [online]. 2011, vol.25, n.3, pp. 577-585. ISSN 0102-3306.  http://dx.doi.org/10.1590/S0102-33062011000300010.

The data presented in this article are the results of field collections and the analysis of fungal specimens deposited in the URM Herbarium. The field trips were carried out in four Atlantic Forest remnants in the state of Pernambuco, between June 2008 and May 2009. The revision of specimens housed in the URM was restricted to the Brazilian exsiccatae. Geastrum specimens were examined macro- and microscopically following the traditional methodology used in the group. Geastrum javanicum and G. lloydianum are new records from the Northeastern Region of Brazil. Eight species are new records from the following states: Pará (G. fimbriatum), Ceará (G. lloydianum), Paraíba (G. fimbriatum, G. javanicum, G. schweinitzii and G. entomophilum), Pernambuco (G. lageniforme and G. triplex) and Rio de Janeiro (G. javanicum). In this article we present full descriptions for ten species of Geastrum with pictures and an identification key.
