The original specimens are small plants, –2 cm. in height, once or rarely twice branched, axils acute, tips tapering-acute; colour of dry plants rufous. Specimens from Australia and Brazil (Corner 1953, 350–351) have much larger fruit bodies –7 cm. high, fastigiate, divided several times, with the final dichotomy giving rise to long slender tapered tips.

Spores 9.5–16 × 4.5–7μ, smooth, oblong-ellipsoid, obtuse or subacute.

Hymenium mostly collapsed in type, in Whitelegg's Australian collection basidia 45–70μ long × 12–13μ wide tapered to a narrow base, cruciately subseptate at apex; sterigmata 4, 10–14μ long: hyphae prominently clamped, monomitic. not inflated, 2–5μ wide.

The only recent material collected in New Zealand with spores and fruit bodies similar to T. pusio was found to have a transverse septum across the apical region of the basidium as well as the longitudinal septation. Owing to the collapsed
