ABSTRACT Fungi of the genus Geastrum are known as earthstar fungi, due to the stelliform morphology of their basidiomes. In the Amazon domain, there are 25 catalogued species of Geastrum, with several new records in recent years. Here we report three new species records of Geastrum for the Brazilian Amazon. Geastrum calycicoriaceum and G. rubropusillum were recorded in the southwestern transition zone between Amazon forest and Cerrado savanna. Geastrum calycicoriaceum was recorded for the first time in Brazil.
