Assessment Notes
Justification
Phaeogyroporus hibiscus is a bolete described from Malaysia. It has also been recorded in Australia, but it is unclear whether this occurrence represents part of its natural distribution or an introduction. There are very few documented observations of this species, and it is not possible to establish if it is genuinely rare or under-recorded. Forest loss in Malaysia could lead to population declines, but the only known site so far is within a protected area. Therefore, without more recent records or targeted search efforts it is not possible to confidently estimate population size and trends and the species is assessed as Data Deficient.Taxonomic notes
Originally described as Boletus hibiscus, Phaeogyroporus hibiscus is the only remaining species in the Phaeogyroporus genus (Index Fungorum 2023). However, its taxonomic placement may need further reviewing as most of the species originally assigned to this genus have since been transferred to Phlebopus. Moreover, Raghoonundon et al. (2021) argued that the reason for the transfer of this species from Boletus to Phaeogyroporus rather than Phlebopus is not clear.Geographic range
This species was described from the Bako National Park in Sarawak, Malaysia. It was later recorded in Queensland, Australia (GBIF.org 2023), but because this site lies below the Wallace line, it is not clear whether this represents its natural distribution or an introduction.Population and Trends
Phaeogyroporus hibiscus was documented in 1972 in the Bako National Park in Sarawak, Malaysia (in two forested bays within the park) and in 1989 in Queensland, Australia (GBIF.org 2023). In the original description of the species, Corner (1974) reported finding 150 fruitbodies in two sites within the Bako National Park and described them as large and bright brownish yellow. This suggests that the species is likely easy to detect, so the absence of records could indicate that it is now uncommon or confused with other similar species, especially in Australia where search efforts are higher. The only known location in Malaysia is within a protected area, but forest loss in Sarawak (World Resources Institute 2023) could lead to declines in the population for other unknown sites in the region. Without more recent records or targeted search efforts it is not possible to confidently estimate population size and trends.
