Habitat loss from deforestation for oil palm plantation in tropical forests and partly collecting by local communities especially in Malaysia for medical properties. In Southeast Asia, more than 50% of Malaysia and Indonesia oil palm plantations in 2005 were on land that was forest in 1990 (Koh and Wilcove, 2008). Modification of substrates due to habitat loss will reduce population of species.
Amauroderma rugosum (Blume & T. Nees) Torrend, 1920
Synonym: Amauroderma atrum (Lloyd) Corner, 1983
Amauroderma rugosum is a normally widespread in other regions but has been evaluated as a least concern (LC). This wild medicinal fungus always be consumed by indigenous communities in some countries. Collecting of this wild medicine fungus by human (Indigenous communities) and deforestation of diterocarp trees widely will reduce the population of fungus and degrade their natural habitat particulary in tropical rainforest regions in Thailand, Malaysia, Indonesia and Papua New Guinea
Species can be found in tropical and subtropical areas. Also found outside the neotropical region as same as other (A. perplexum, A. rude) and clustered in a distinct lineage from Amauroderma s.str., as also observed by Costa-Rezende et al. (2016). A few reports are from the USA but these have to be confirmed.
Population of species worldwide are facing habitat homogenization due to human activities especially in Asia. A low population density for this species in most regions due to extremely unfavorable habitats (substrate unfavourable for this saprophyte fungus) and habitat quality reduction then the species shows declines in some countries. Unclear of current trends of this species can be observed in most regions.
Population Trend: Uncertain
The species is growing as saprophytic (wood-decay fungi) on the ground with other plants and common in lowland dipterocarp of tropic forest and sub-tropic forest. The most suitable elevation for the growth and development of Amauroderma rugosum within on elevation of 200-1400m a.s.l. The higher humidity than 90% is the best for the growth and development of this species (Nguyen & Khanh, 2017).
In 2011 Conservation International listed the top 10 most endangered forests, characterized by having all lost 90% or more of their original habitat. Remaining habitat of endangered forests in Indo-Burma, New Caledonia, Sundaland, Philippines, Atlantic Forest, Mountains of Southwest China, California Floristic Province, Coastal Forests of Eastern Africa, Madagascar & Indian Ocean Islands and Eastern Afromontane only left between 11% and 5%.
