Metuloidea reniformis is a decomposer of wood and can be found in groups from February through October. Named in 2021, older literature may reference species matching this morphology as Steccherinum reniforme, Steccerinum rawakense, or Steccerinum subrawakense.

The cap is thin and is attached to wood without a stem (sessile). Generally colored brown with zones of different color, though it can fade with age to be whitish with or without zones. The surface under the cap in young specimens can look like fine, reptilian scales (which are densely crowded teeth), which later grow into distinguishable tooth-like structures with age.
