This is a macromorphological variable species, characterised by globose, distinctly ornamented basidiospores [7‒9 (‒10) μm]. Some specimens are similar to A. sprucei (Pat.) Torrend, which has white context without black lines (Gomes-Silva et al. 2015).
Why suggested for a Global Red List Assessment?
Species widely distributed in the Neotropics, with highest occurrence in Brazil. Reports in Africa should be revaluated, since Amauroderma s.s. is a neotropical taxon (Sun et al 2020).
Population and Trends
There are about 600 reports of this species in GIBF, most of them in Brazil.
Population Trend: Uncertain
Habitat and Ecology
Species with wide distribution throughout the country, present in four biomes: Amazon, Atlantic Forest, Caatinga and Cerrado.
It presents no evident threat, being very common at least in Brazil. However, it is found in the Atlantic Forest, a hotspot, in the Amazonia (currently being deforested at the highest rates in the last decades) and Cerrado (also a hotspot).
