Heterotextus pezizaeformis is very similar to H. miltinus in size and colour, but the centre of the fruiting body is concave.

Basidiocarps: Gregarious or scattered, forming small patches on decayed wood. Stipitate and pileate, but very small overall; fruitbody to ~3 mm high. Pileus cupulate or obliquely cupulate, often slightly tilted. 2–5 mm diameter. Exterior roughened, sometimes tuberculate, and typically dingy white when dry. Consistency firm‑gelatinous, less collapsible than H. miltinus.
Growth Habit: Occurs scattered or in loose groups, often on small fragments of decayed wood. Cups usually upright, sometimes oblique depending on substrate texture. Retains its cup shape better than H. miltinus, which often collapses.
Colour: Orange‑yellow when fresh. Dries to dull wine‑red or red‑brown, with the outer surface dingy white. Colour contrast between the bright interior and pale exterior is often noticeable.
Substrate: On angiosperm wood. In New Zealand, found on rotting broadleaf wood in forest and shrubland habitats.
