Abstract

Abstract Dungus Iwul Nature Reserved (CADI) is a remnant patch of tropical rainforest converted into plantations with neither past data nor study in macrofungi. In this article, we explored and identified macrofungal fruitbody in CADI and PTPN VIII Oil Palm Plantation (PTPN) around the nature reserve. The inventory was carried out with the opportunistic sampling methods assisted by the line intercept. Morphological characteristics were used to identify the macrofungal fruitbodies species. We found that the species richness in the study area stood at 120, with 70 species found in CADI, 23 species in PTPN planted in 2003, and 57 species in PTPN planted in 2004. These 120 species consist of 76 genera, 41 families, 11 orders, and four classes in Subkingdom Dikarya. Schizophyllum commune and Marasmiellus candidus in CADI and S. commune in PTPN planted in 2003 and 2004 were the species found with the highest relative frequency. Neither sign of basal stem rot on oil palm trees nor Ganoderma fruitbodies were found in both PTPN study locations, even though the fruitbodies were found in CADI. Further research is needed to determine if nature reserve could be a barrier against pathogens of monoculture oil palm plantation in a similar landscape model.
