On charred wood.
Pileo e carnoso suberoso, ungulato, glabro, albido, demum pallido, cute rivuloso-fatiscente, intus niveo, spongioso, tenae.i; hymenio convexo, rimoso ; poris angulatis, minimis, brevibus, albis. (vix P. betulinus.)
Substance snowy-white, not at all fragile as in P. officinalis, but firm and tough ; pileus 6 inches across, 4 inches high.
Cunningham (1965) stated that collections of this species were earlier identified as Polyporus eucalyptorum Fr., but, as the type of this species is missing, the species cannot be identified. In New Zealand in indigenous forests it occurs only on Nothofagus spp., where it causes a cubical heart rot. It has also been collected on a pear tree (Pyrus communis) in Hawke's Bay.

Pore surface plane or slightly convex, creviced when old, straw- or honey-coloured; pores large, 1–3 per mm. Context white, soft and crumbling. Hyphal system dimitic. Basidiospores globose or subglobose, 7–9 × 7–8 μm, smooth, hyaline.
Distribution: Northland, Auckland, Coromandel, Bay of Plenty, Taupo, Wellington, Gisborne, Hawkes Bay, Buller, Marlborough Sounds, Mid Canterbury, Dunedin.; 1st Record: Cunningham (1927: as Polyporus eucalyptorum).
