Stemonaria fuscoides (Stemonitaceae, Myxomycetes): a new record for Brazil

Studies are being carried out in Brazilian mangroves with the aim of contributing to the knowledge of myxomycetes from ecosystems associated with the Atlantic forest. A total of 330 moist chamber cultures were prepared with aerial litter, ground litter, tree bark, and small woody twigs of Conocarpus erectus (Combretaceae), Rhizophora mangle (Rhizophoraceae), and Acrostichum aureum (Polypodiaceae). Four specimens of Stemonaria fuscoides were obtained from the cultures prepared with R. mangle and C. erectus. Previously, Stemonaria was represented in Brazil only by S. longa, cited for the North (Amazonas State), Northeast (Bahia, Pernambuco, Ceará and Piauí States), Southeast (Rio de Janeiro and São Paulo States), and South (Paraná State), and S. irregularis, cited for the states of Ceará and Pernambuco. Stemonaria fuscoides is recorded for the first time for the Neotropics and in a mangrove environment.
