Amauroderma praetervisum is characterised by the dark, strongly zonate and thick pileus, and finely ornamented, globose to subglobose basidiospores (9‒12 × 9‒11 μm). The species is easily confused with A. omphalodes and A. pseudoboletum which have more ellipsoid basidiospores (Ryvarden 2004; Gomes-Silva et al. 2015).
Neotropical species known in 14 countries, but mostly recorded in Brazil. Reports other than the Neotropics should be revaluated.
The species has about 145 occurrences, according to GBIF.
Population Trend: Uncertain
This species occurs in four Brazilian biomes: Amazon, Cerrado, Atlantic Forest and Caatinga.
The species is well distributed in Brazil. However, the Amazon has currently the highest rates of deforestation in the last decades, the Atlantic Forest and Cerrado are already hotspots, and Caatinga is threatened with desertification.
Several records are in protected areas.
Other countries should be better surveyed for a better understanding of distribution of the species.
