This study was performed to determine if several moderately-utilized Peruvian hardwoods had potential for spalting applications. We applied a modified decay jar methodology with six native Peruvian woods and three moulds, with a period of incubation of six weeks. Results showed that Nigrospora sphaerica and Marupa (Simarouba amara) resulted on the highest significant internal pigmentation (black), followed by Congona (Brosimum alicastrum) and Zapote (Matisia cordata) tested with Cladosporium herbarum. No spalting occurred on woods with darker sapwood – spalting occurred only on white woods.
