With the characters of the species, save that the hymenium is irregularly pitted with shallow depressions 1-2 mm. deep, often labrynthiform towards the centre; pores are present in both depressions and ridges.

Probably the most abundant species of Fomes present in the Dominion. In a former paper (1927, p. 218), following identifications made by the late C.G.Lloyd, I referred the species and form to F. subtornatus (Murr.) Lloyd. Following examination of the type of this last, and of specimens from New Zealand, C.J.Humphrey in correspondence advised that our plant did not resemble F. subtornatus, but agreed with Philippine specimens of F. mastoporus. The hymenial configuration is striking. Pores are minute owing to partial blockage of orifices, and are often set in rows with part of the wall suppressed; in the form the condition is carried further. Pores may appear in small depressions or the intervening ridges, both being so arranged that the surface is labrynthiform, save the periphery which may be plane. As even in the smallest and youngest specimens the condition is present, it is evidently a constant feature. In size, plants range from small buttons 2 mm. wide, to applanate or occasionally ungulate forms 10-20 cm. in length. One specimen reached the large size of 50 x 30 cm., but this is unusual. Spathulate or digitate forms, with lateral stem-like extensions of the pileus, are not uncommon.
