The abundance and diversity of Basidiomycetes fungi in sago bark waste

Abstract

This study was aimed to determine the abundance and diversity of Basidiomycetes fungi on sago bark waste. This research was conducted in January-February 2020 at Tondok Alla village, Telluwanua district, Palopo city (as location I) and Kalotok village, South Sabbang district, North Luwu regency (as location II). Climate data for the study period were obtained from the BMKG online website. The morphology of the fungi obtained from the sago bark waste was observed and identified morphologically for stalk color, cap structure and cap colour. The number of identified Basidiomycetes were analyzed to obtain relative abundance, species richness, evenness, Shannon Wiener diversity index, Simpson dominance index, and community similarity index. The climate observation results showed that, the average temperature was 27.74 (° C), 80.36% humidity, 12.37 mm of rainfall, and 4 hours / day of sun exposure. The fungi observation results showed that, several species of Basidiomycetes fungi was observed at both locations. Schizophyllum commune is the dominant species at both sites, and Ganoderma sp. the least. The species richness index, species evenness index, and diversity index at location I were higher than location II, while the Simpson dominance index was the highest in location II. Both locations have the same community structure based on the similarity index.
