Genus Tremellodendropsis (Corner) D.A. Crawford

Tremellodendropsis has basidia that are partially and secondarily longitudinally septate (cross-walls extend down from the apex). The following species are recognized on Index Fungorum, but DNA analysis is needed to sort out species limits and generic placement. Several species are recorded in North America; Tremellodendropsis tuberosa is the best known. This genus is visually similar to and easily confused with Sebacina (Tremellodendron) when identifications are based on photos, such as iNaturalist and Mushroom Observer.

Tremellodendropsis was split out of Aphelaria in 1954. They were treated as part of Clavariaceae but have since parted company. Tremellodendropsis with partially septate basidia was moved to the Tremellales, then the Auriculariales, and now its own order Tremellodendropsidales.
