Notes on gasteroid fungi of the Brazilian Amazon rainforest

Studies of gasteroid fungi have been limited in Brazil, where the group is poorly known. Although the Brazilian Amazon rainforest is an area of high biodiversity, very few gasteromycetes have been reported for the ecosystem. As a result of recent fieldwork in the state of Rondônia (Brazil's North Region) where gasteroid fungal specimens were collected, a new species was identified that is described here as Cyathus amazonicus. Phallus indusiatus and Geastrum fimbriatum are also newly recorded from the Brazilian Amazon rainforest.
