Hyphoderma orphanellum is a corticioid fungus in the family Polyporaceae, assessed as Near Threatened (NT). It forms thin, resupinate fruiting bodies on dead wood of broadleaf trees in mature or old-growth forest environments. Its near-threatened status reflects its sensitivity to the removal of deadwood and disturbance of old-growth forests.
