Amanita aporema is quite similar to and can be
misidentified as A. princeps. Both species are associated
with Dipterocarps in Southeast Asia.
This fungus is associated with Dipterocarps in lowland rain forests of Indonesia and Malaysia and areas of lowland rain forest are decreasing rapidly due to logging and land-use changes.
So far this fungus has only been found growing in association with Dipterocarps in lowland rain forests of Sumatra, Indonesia and Peninsular Malaysia. In Indonesia, the fungus was found in 1924 at about 1000 m asl, Batang Paloepoeh, West Sumatra and has not been reported since. In Malaysia, it has been found in lowland rain forest dominated by Dipterocarps in the states of Selangor and Johor in the peninsula. It is not known whether it is present in the East Malaysian states of Sabah and Sarawak.
Insufficient information due to paucity of studies.
Population Trend: Uncertain
Solitary or growing in small groups on the ground in lowland rain forest dominated by Dipterocarps.
Lowland rain forests in Indonesia and Malaysia are under threat from logging and conversion into oil palm plantations and plantations of fast-growing exotic tree species.
Intensive and long-term fungal surveys and inventories are needed in the region to obtain more information on the occurrence and distribution of this fungus (and others).
