Exidia alveolata is a species of fungus in the family Auriculariaceae. Basidiocarps (fruit bodies) are gelatinous, pale smoky brown, alveolate (shallowly pitted like a honeycomb), and with sparse pegs or spicules on the surface. The species is currently known only from its original collection in Ecuador.
Exidia alveolata forms smoky brown, gelatinous fruit bodies that are effused and alveolate, around 4cm (02inches) across. Small hyphal pegs or spicules are scattered on the surface.
The microscopic characters are typical of the genus Exidia. The basidia are ellipsoid, septate, 14 to 17 by 10 to 12.5 μm. The spores are weakly allantoid (sausage-shaped), 10.5 to 16 by 4 to 6 μm.
