This crust fungus is found in Belize, where it grows on decomposing wood.
[1] Molecular analysis suggests that the genus belongs in the family Steccherinaceae.
[2] The fruit body of Atraporiella neotropica is in the form of a small crust fungus, with length and width dimensions of up to 2 to 3 cm (0.8 to 1.2 in), and a thickness of up to 10 mm (0.4 in).
When fresh, the pore surface is white, but it readily stains dark brown to black when bruised.
The spores are ellipsoid, thin-walled, smooth, hyaline (translucent), and do not react with Melzer's reagent.
