Assessment Notes

Taxonomic notes

Why suggested for a Global Red List Assessment?

This is a rare, easily identifiable Amanita species that has recently been described from Northern Thailand. Forests in the known distribution area are under threat from human activities like recurrent burning and tea or coffee plantation.

Geographic range

Known only from two localities in Chiang Mai Province, Northern Thailand (Thongbai et al. 2017; O. Raspé pers. obs.).

Population and Trends

Known only from two localities in Chiang Mai Province, Northern Thailand (Thongbai et al. 2017; O. Raspé pers. obs.). In Doi Suthep-Pui National Park, the species has been found in different sites at elevations between 740 m and 1170 m, so the population is presumably large. The size of the other known population is uncertain.

Population Trend: Uncertain

Habitat and Ecology

The species has been observed both in semi-deciduous forest dominated by Dipterocarpaceae and evergreen hill forests dominated by Fagaceae. Presumably ectomycorrhizal


Forests cover in Northern Thailand was reduced by more than 75 % between 1915 and 1995, mostly because of conversion to cropland (Delang, 2002). Despite protection measures and reforestation, Thailand lost 7.8 % of Intact Forest Landscapes between 2000 and 2013 (Potapov et al 2017). In the area where Amanita ballerina is known to occur, forests continue to be degraded by human activities (e.g., tea or coffee plantation, recurrent burning).

Conservation Actions

Research needed

The distribution needs to be better known. The ectomycorrhizal symbiotic partners should be identified.

Use and Trade

No use known.
