Assessment Notes

Taxonomic notes

Originally described by J.S. Furtado in 1968 as A. trichodematum.  Gerardo et al. recognize this as a misspelling of trichodermatum, and consider the original epithet as an orthographic variant.

Why suggested for a Global Red List Assessment?

Amauroderma trichodermatum is a rare and charistmatic polypore with a concentrically zonate, hirsute pileus, which is only known from four collections worldwide.  It is only known from Amazon rainforest, (though its distribution suggests it may also occur in other lowland Neotropical forests), which is under an array of threats from resource extraction and development.

Geographic range

Amazon rainforest, though based on known distribution, this species may occur in other lowland rainforests in South America.

Population and Trends

All of the collection/observation sites of A. trichodermatum are within the Amazon rainforest biome, which is under an array of threats across South American nations, principally in the form of deforestation from development and resource extraction projects.

Population Trend: Decreasing

Habitat and Ecology

Subtropical/Tropical Moist Lowland Forest


The Amazon rainforest is experiencing the greatest continuous deforestation event on Earth.  The reasons for this destruction of habitat are varied, and depend on the economic and political priorities of each Amazonian country.

Conservation Actions

Research needed

More surveys of Amazonian funga are required to better understand the true range and rarity of A. trichodermatum.

Use and Trade

None known.
