One specimen was identified as C. chrysomycelinus and the other is described as a new species, C. cristatus, which is distinguished by its pale red to pink receptacle and crests along the edge. Full descriptions with illustrations of the collected specimens and a key to species of Clathrus from Brazil are provided.help during the fieldwork and Tereza Cristina de Oliveira Galvão for the illustration.

New distributional data on Geastrum (Geastraceae, Basidiomycota) from Brazil

[EN] (New distributional data on Geastrum (Geastraceae, Basidiomycota) from Brazil). Th e data presented in this article are the results of fi eld collections and the analysis of fungal specimens deposited in the URM Herbarium. Th e fi eld trips were carried out in four Atlantic Forest remnants in the state of Pernambuco, between June 2008 and May 2009. Th e 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. fi mbriatum), Ceará (G. lloydianum), Paraíba (G. fi mbriatum, 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 identifi cation key.[POR] (Novos dados de distribuição de Geastrum (Geastraceae, Basidiomycota) no Brasil). Os dados apresentados neste artigo são resultados de coletas feitas em campo e análise de espécimes fúngicos depositados no Herbário URM. As coletas foram realizadas em quatro remanescentes de mata atlântica no estado de Pernambuco, entre junho/2008 e maio/2009. A revisão de espécimes depositados no URM foi restrita a exsicatas brasileiras. Os espécimes de Geastrum foram examinados macro e microscopicamente segundo a metodologia tradicional do grupo. Geastrum javanicum e G. lloydianum são novos registros para a região Nordeste do Brasil. Oito espécies são novas ocorrências para os seguintes estados: Pará (G. fi mbriatum), Ceará (G. lloydianum), Paraíba (G. fi mbriatum, G. javanicum, G. schweinitzii e G. entomophilum), Pernambuco (G. lageniforme e G. triplex) e Rio de Janeiro (G. javanicum). Apresentamos neste artigo dez descrições completas de espécies de Geastrum, além de fotos das espécies e uma chave de identifi cação.Peer reviewe
