A recent survey in areas of the Amazonia and the Atlantic Forest in Brazil, and revision of the exsiccates deposited in herbaria INPA, SP and URM resulted in new records of Hymenochaetaceae: eight for the State of Rondônia, one for Acre, Amapá and Amazonas, three for Pará and two for Roraima. Coltricia barbata, C. duportii, Hymenochaete porioides and H. unicolor are new records to the Brazilian Amazonia, while C. velutina is recorded for the first time after its description.
