Abstract
The genus Heimioporus was previously proposed as Heimiella by Boedijn from Indonesian specimens. Currently, the knowledge of Indonesian Heimioporus is limited due to a lack of field sampling. The only notable Heimioporus from Indonesia is jamur pelawan (local name), a wild edible mushroom from Bangka-Belitung Province, for which the taxonomical identity remains unclear. During a mushroom collecting field trip near Kendari (Indonesia) in 2024, a wild edible bright red bolete mushroom resembling Heimioporus was encountered, and specimens were collected. The current study confirms the taxonomical identity of our specimens. Fresh fruiting bodies were evaluated for morphological and molecular evidence. The basidiomata were described based on the macro- and micromorphological characteristics. Molecular analysis and phylogenetic tree construction were performed using the ITS (Internal Transcribed Spacer) locus. The combination of morphological and molecular analyses confirmed our collection as H. retisporus. Our study proves that the previous Indonesian Heimioporus collection from Bangka-Belitung Province was not H. retisporus. The indigenous people in the area where H retisporus was collected consume this wild edible mushroom and sell it at local markets.
