 Add this item to the list  Elfvingia australis (Fries) comb. nov.
Page number:256 
Remarks (internal):Separated from related species present in the region by the larger pores and spores, constant in all collections recorded. The type of Polyporus australis, collected on a Pacific Ocean Island is not now in Fries's herbarium. One so labelled by Fries, now in Kew herbarium, is probably a neotype since it is labelled as to locality as in Elenchus Fungorum and agrees with the specimens described above save that the cortex is now missing. Spores are of the dimensions given and are larger than those of Elfvingia tornata to which the species was referred by Murrill (1908, p. 115). Elfvingia brownd is a synonym as I have ascertained by examination of an authentic collection so named by Murrill. The type of the latter has a yellow hymenial surface, but is otherwise identical. The yellow condition is present in several specimens of three species from this region, therefore is without specific significance. Following the naming of a New Zealand collection by C. J. Humphrey as Ganoderma brownii, the species was so recorded (as Fomes) in a former paper (Cunningham 1948g, p. 21).

Hymenophore perennial, solitary, firm and woody, attached by a lateral base. Pilei applanate or ungulate, 7-30 cm wide, 5-20 cm radius, 2-11 cm thick; pileus surface grey, some shade of brown, or almost black when old, concentrically sulcate, often tuberculate; cortex 1-8 mm thick, black, shining, hard, brittle, of densely intertwined cemented hyphae, rimose, fissures developing both laterally and vertically; margin obtuse, even, concolorous; hymenial surface ochre, bay, or reddish brown where bruised, even, with a sterile border 2-10 mm wide. Pores vaguely stratose, 2-7 mm long in each layer, umber, 3-4 per mm, 150-300 µm diameter; dissepiments 100-150 µm thick, equal, apices finely velutinate. Context occupying about one-third of the pilei, chocolate, zoned, of densely intertwined hyphae; skeletal hyphae to 6 µm diameter, walls thickened, fuscous; binding hyphae to 6 w diameter, freely branched, aseptate, branches tapering, tortuous, lumena almost capillary, walls fuscous; generative hyphae to 3 µm diameter, branched, septate, walls 0.2 µm thick, hyaline. Hymenial layer to 20 µm deep, a close palisade of basidia and paraphyses, soon collapsing. Basidia clavate, 10-14 x 9-11 µm, bearing 2-4 spores; sterigmata arcuate, to 4 µm long. Paraphyses clavate, 8-12 x 7-10 µm. Spores elliptical or ovate, 11-13 x 6-9 µm, walls coarsely punctate, appearing verruculose with spines often in striae, to 2 µm thick, apices sometimes truncate, yellow-brown.
