Cunningham (1948f) misidentified some specimens of this fungus as Fomes setulosus. It is responsible for a pocket heart rot of a number of indigenous timber trees.

Type: Lignicolous Fungi; Description: Basidiomata perennial, solitary, firm and woody, attached by a broad lateral base. Pilei ungulate, applanate or occasionally subglobose, 50–300 mm wide, 30–150 mm thick. Pileus surface tomentose, concentrically coarsely sulcate and ridged, frequently creviced when old, at first cinnamon brown, darkening to black, margin entire, reddish brown. Pore surface plane, often creviced, with a sterile border 2–5 mm wide, reddish brown to dark brown; pores stratose, small, 5–7 per mm. Context cinnamon brown. Hyphal system dimitic. Setae usually present, ventricose, base inflated and narrowing towards the attachment point, apex acute, 16–24 × 6–12 μm, chestnut brown. Basidiospores globose to subglobose, 6–7 × 5–6 μm, smooth, hyaline.
Distribution: Northland, Auckland, Coromandel, Waikato, Bay of Plenty, Taranaki, Taupo, Wellington, Hawkes Bay, Wairarapa, Nelson, Buller, Westland, Fiordland, Marlborough Sounds, Marlborough, Kaikoura, Mid Canterbury, Central Otago, Dunedin, Southland, Stewart Island.; 1st Record: Cunningham (1927: as Fomes robustus).
Significance: Causes a white-pocket heart rot in many living indigenous trees and shrubs. Considered to be of little significance. Cunningham (1927) recorded this fungus as the cause of death of Ozothamnus leptophyllus (≡ Cassinia leptophylla) in coastal regions of Wellington and Wairarapa.; Host(s): Beilschmiedia tawa, Coprosma grandifolia, C. macrocarpa, C. rhamnoides, C. robusta, Dysoxylum spectabile, Eucalyptus sp., Kunzea ericoides, Leptospermum scoparium, Meryta sinclairii, Metrosideros robusta, M. umbellata, Myrsine australis, Nothofagus fusca, N. menziesii, N. solandri var. cliffortioides, N. truncata, Ozothamnus leptophyllus, Quercus suber, Weinmannia racemosa.

taxonomic status
F. robusta sensu stricto may be present as an introduction and associated with oaks and perhaps other northern trees. That requires confirmation. The collections on indigenous hosts (Fomes setulosusu sensu Cunningham) represent multiple indigenous species. The common species associated with Leptospermum is related to F. eucalypti and tagged F. sp. 'Mt Lyford' [JAC]
