Assessment Notes

Taxonomic notes

Amanita malayensis is molecularly well-defined
without close phylogenetic relatives in the Asian
mycota. Based on the data presented in this study, its
closest phylogenetic relatives are A. javanica, A. rubromarginata,
and Amanita sp.1.

Why suggested for a Global Red List Assessment?

This fungus has only been recorded growing in association with Hopea odorata (Dipterocarpaceae) from one location in a popular public park.

Geographic range

In Malaysia, this ectomycorrhizal fungus has been found growing in small groups among planted Hopea odorata (Dipterocarpaceae) in a public park in the state of Perak and in an urban park in the state of Penang. According to GenBank data (ITS: AB451969, AB458887), this taxon occurs in Thailand and is misidentified as A. hemibapha subsp. javanica. It has also been observed growing in association with Dipterocarpus alatus and Shorea spp. in northeast Thailand.

Population and Trends

Amanita malayensis has only been reported from two park-like sites in Malaysia growing in association with planted Hopea odorata (Dipterocarpaceae). It has also been reported from north-east Thailand growing under Dipterocarpus alatus and Shorea sp. Information on its natural range, habitat and population status is presently inadequate.

Population Trend: Uncertain

Habitat and Ecology

This ectomycorrhizal fungus grows in small groups forming fairy-rings under Hopea odorata in Malaysia. It was collected from the same location in one public park during the months of July and March, in 2007 and 2008, respectively and most recently observed under H. odorata in an urban park in another location in May 2019. In Thailand it has also been observed forming fairy rings under Dipterocarpus alatus and Shorea sp. in north-east Thailand. More information is needed about its natural habitat and distribution.
