<p>This study evaluated the natural resistance of six Amazonian wood species: <em>Aspidosperma desmanthum</em> (Araracanga)<em>, Parinari excelsa</em> (Parinari)<em>, Mouriri callocarpa</em> (Miraúba)<em>, Marmaroxylon racemosum</em> (Angelim-rajado)<em>, Peltogyne paniculata</em> (Roxinho)<em> e Astronium </em>sp. (Muiracatiara) against <em>Pycnoporus sanguineous</em>, a white rot fungus, and <em>Gloeophyllum trabeum</em>, a brown rot fungus. Testing was performed based on the American Society for Testing and Materials - Standard Method for Accelerated Laboratory Test of Natural Decay Resistance of Woods - ASTM D2017/81(86). Results showed that all tested wood species were classified as very resistant to both decay fungi, except the wood of <em>Aspidosperma desmanthum</em>, which demonstrated to be very resistant to <em>Pycnoporus sanguineous</em> and resistant to <em>Gloeophyllum trabeum</em>. The wood of <em>Peltogyne paniculata</em> showed the best performance against <em>Pycnoporus sanguineous</em>, whereas the wood of <em>Astronium</em> sp. presented the best results when submitted to <em>Gloeophyllum trabeum</em> attack.</p>
