Assessment Notes

Taxonomic notes

Amanita sculpta Corner & Bas, Persoonia 2(3): 255 (1962); Bas, Persoonia 5: 483 (1969); Yang, Biblioth. Mycol. 170: 147 (1997); Cui et al., Fung. Diversity 91: 172 (2018). – TYPE: Singapore, Bukit Timah, 9 July 1940, Corner s.n. (holotype L [L0053718]). (Fig. 1–3).


Why suggested for a Global Red List Assessment?

Seen first time since Corner described it in 1962 in Singapore


Geographic range

This species has been found throughout the region from Singapore, Peninsular Malaysia, Borneo, Brunei, Indonesia, Laos and Japan to as far north as the subtropical forest zones of China. Amanita sculpta Corner & Bas was first collected by Corner on 15 October 1939 (in bud stage) and thereafter observed on several other occasions by him in September 1940 at the same spot in Bukit Timah Nature Reserve. Corner noted that he had not seen it elsewhere in Singapore and Malaya (Corner & Bas, 1962). It has since been recorded from Peninsular Malaysia (Watling & Lee, 1995; Turnbull & Watling, 1999; Lee et al., 2012; collection Lee FRI 72557, 9 Dec 2011, Pahang, KEP ), Brunei (collection Corner s.n., 15 Feb 1959, E), Sabah (Kota Kinabalu: Bas,1969; Crocker Range Park: collection Jaya Seelan BORH0072, 12 May 2008, BORH; Mt Kinabalu: collection Jaya Seelan BORH0212, 22 Oct 2009, BORH), Kalimantan (collection Corner RSNB 581, 13 Jun 1961, E), northern Thailand (Sanmee et al., 2008), Laos & Japan (GBIF Secretariat, 2019), and China (Yang, 1997, 2015; Yang & Li, 2005; Cui et al., 2018). A check with the curators of the regional herbaria BO, BRUN, SAN and SAR yielded no further records of the species. In Singapore the species was recently (2020) collected after a 75 year gap.  It is also to be noted that the few published records of Amanita sculpta in Peninsular Malaysia are all based on an observation and illustration by S.-S. Lee (SS. 627) (Watling & Lee, 1995; Turnbull & Watling, 1999; Lee et al., 2012), although there is the additional collection cited above.


Population and Trends

The species is broadly distributed throughout much of South East Asia, but infrequently encountered in parts of its range. It has been reported growing in forests dominated by either Dipterocarpaceae or Fagaceae.  The species population likely has been under ongoing decline due to deforestation and habitat disturbance through much of its range.

Population Trend: Decreasing


Habitat and Ecology

The species forms ectomycorrhiza in forests dominated by either Dipterocarpaceae or Fagaceae.  Most records have been from undisturbed habitats, community forests or protected areas.

Subtropical/Tropical Moist Lowland Forest

Threats

Most reports of this species are from less disturbed areas including community forests and protected areas.  The species population likely has been under ongoing decline due to deforestation and habitat disturbance through much of its range.

Agro-industry farmingUnintentional effects: subsistence/small scale (species being assessed is not the target) [harvest]

Conservation Actions

Habitat protection outside of the preserves.

Site/area protection

Research needed

Surveys to better document the species distribution and ecology are needed.
