Novos registros de Geastraceae Corda para o Nordeste brasileiro

The present study deals with the occurrence of  Geastraceae from Atlantic Rainforest and Caatinga biomes in the region encompassed by the states of Rio Grande do Norte and Pernambuco. Four species have been identified: Geastrum saccatum, G. schweinitzii, G. triplex and Myriostoma coliforme, all of them representing new records from Rio Grande do Norte. The material collected was added to the herbarium URM and UFRN-fungi. Descriptions of macro and microscopic features are given, including taxonomic and ecological comments.O presente estudo aborda a ocorrência da família Geastraceae em alguns biomas de Mata Atlântica e Caatinga, situados nos Estados do Rio Grande do Norte e Pernambuco. Como resultado, foram identificadas quatro espécies: Geastrum saccatum, G. schweinitzii, G. triplex e Myriostoma coliforme, todas representam novos registros para o Rio Grande do Norte. Os exemplares coletados se encontram depositados nos herbários URM e UFRN-fungos. São fornecidas descrições e ilustrações macro e microscópica das espécies, além de comentários, observações ecológicas e chaves de identificação

Notas sobre Phallales en los neotrópicos.

[EN]Some interesting species of Phallales are reported from Atlantic rainforest areas in Northeast Brazil. Eight species are described: Aseroë floriformis, Geastrum setiferum, Ileodictyon cibarium, Laternea triscapa, Mutinus caninus, Phallus indusiatus, P. pygmaeus and Staheliomyces cinctus. Original colour photos and comments on the taxonomy and ecology of these species are also given.[ES] En este trabajo se describen ocho especiees raras o interesantes de Phallales, prodecentes de bosques lluviosos de influencia atlántica del NE de Brasil: Aseroë floriformis, Geastrum setiferum, Ileodictyon cibarium, Laternea triscapa, Mutinus caninus, Phallus indusiatus, P. pygmaeus and Staheliomyces cinctus. Se añaden ilustraciones en color y comentarios sobre la taxonomía y ecología de las especies estudiadas.Peer reviewe

An emendation of Phallus glutinolens

[EN] Phallus glutinolens was described from Brazil by Möller in 1895. A new collection of P. glutinolens from the Brazilian Atlantic Forest revealed that Möller’s original description was based on young specimens. New information on morphology is provided for P. glutinolens, and an emendation of the species circumscription is presented. This article also presents a key to differentiate the known Brazilian members of the genus Phallus.Peer reviewe

First records of Clathrus (Phallaceae, Agaricomycetes) from the Northeast Region of Brazil

Two Clathrus specimens were collected in Northeastern Brazil during the rainy season in 2008. 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. The Brazilian authors also thank CNPq for providing Master fellowship to Larissa Trierveiler- Pereira and PPBio for financial support.Peer reviewe

Additional studies on Geastrum from northeastern Brazil

Surveys on Geastrum diversity from areas of northeastern Brazil have been carried out in the last years. Three species belonging to the genus Geastrum were reported for the first time from this region: G. coronatum, G. funbriatum and G. hieronymi and three from the rest of Brazil: G. elegans, G. fornicatum and G. ovalisporum. Descriptions, comments and illustrations of basidiomata are given.Conselho Nacional de Desenvolvimento Científico e TecnológicoPeer reviewe

Rick's species revision: Mitremyces zanchianus versus Calostoma zanchianum

[EN] After the revision of Mitremyces zanchianus we confirm this species as a valid name in the Sclerodermataceae and propose a new combination to the genus Calostoma. Description and ilustrations of the type and SEM images of the basidiopores are given.Peer reviewe

Rick's species revision 2: Lycoperdon benjaminii recombined in Morgonella.

[EN] Continuing the study of J.Rick's species, we consider Lycoperdon benjaminii as an authentic member of Lycoperdaceae and propose its transference to eh genus Morganella. Description and ilustrations of the holotype and SEM images of the basidiospores are given, as well as an updated key for the South American species of the genus.Peer reviewe
