Description

• Etheirodon is a genus of freshwater fungi in the family Sordariaceae. The genus is associated with microscopic, filamentous fungi that produce small reproductive structures on submerged or water-associated organic material. Species are generally inconspicuous and are more readily recognised through their microscopic structures than by conspicuous fruiting bodies.

Range

• Etheirodon is associated primarily with freshwater environments in tropical and subtropical regions. Species occur in the Americas, including Mexico, and the genus may be encountered in the Zihuatanejo region where suitable freshwater habitats and submerged organic substrates are present.

Habitat

• Species are associated with submerged or partially submerged plant material, woody debris, and other decomposing organic substrates in freshwater. They may occur in streams, pools, ponds, and other slow- or flowing-water environments, particularly where fallen vegetation and woody material remain in the water.
