Hymenophore annual, reviving a second season, corky-woody, solitary or imbricate, attached by a lateral base. Pilei applanate or conchate, occasionally ungulate, 2-16 cm wide, 2-8 cm radius, 5-15 mm thick; pileus surface straw colour, tan or bay, darker when old, glabrous, concentrically sulcate and ridged, strongly radiate-striate, ridges sometimes to 3 mm tall; without a cortex; margin acute, entire concolorous; hymenial surface rose, lilac, violaceous, or pinkish-brown, reflecting surface irregularities, with a narrow concolorous sterile border 1-2 mm wide. Pores rose pink or pallid ferruginous, round or some slightly labyrinthiform, 2-8 mm long, 4-5 per mm, 90-250 I diameter; dissepiments 60-230 µm thick, most about 100 µm, equal, apices velutinate. Context rose, lilac, or pinkish-brown, of parallel hyphae radiately arranged; skeletal hyphae to 6 µm diameter, aseptate, unbranched, walls tinted yellow, 0.5-1 µm thick; binding hyphae to 4 li diameter, aseptate, freely branched, branches tapering and tortuous; generative hyphae to 4 µm diameter, branched, septate, walls hyaline, 0.2 µm thick. Hymenial layer to 24 µm deep, a dense palisade of basidia and paraphyses. Basidia subclavate, 12-16 x 5-6 µm, bearing 4 spores; sterigmata erect, to 5 µm long. Paraphyses subclavate, 8-14 x 4-5 µm. Spores elliptical, apiculate, 6-9 x 2.5-3 µm, walls smooth, hyaline, 0.1 t thick.

IN Kew HERBARIUM: Collections from the region are as follows: under Polystictus lilacino-gilvus are "Q., Daintree River, Pentzke", "N.S.W., Tilba Tilba, Miss Bate", "N.S.W., Nowra, F. A. Rodway", "N.S.W., Illawarra, Karsten", "N.S.W., Pennant Hills, Paramatta River", "N.S.W. Enoggera, W. N. Cheesman",, "Vic., Gippsland,, Murray and Webb",. "Vic., D.F.P. 1106", "Vic., Ballarat, C. French", "Vic., Loddon River, Wallace", "S. Aus., J.B.C. 6", "W. Aus., D.F.P. 1115", "S.W. Aus., Thos Muir", the type ex "V.D.L., Gunn", "Tasmania" and "Van Diemen's Land"; under Fomes carneus are "Q., Brisbane", "Vic., Narranoom, Stranger" and "Vic., Melbourne, G. LeFevre" ; under Trametes rosea is the type ex "Australia"; and under Polystictus cupreoroseus is "Australia".
The species is easily separated from Trametes feei by the strongly radiate-striate surface of the pilei, and pores 4-5 per mm. Skeletal hyphae possess thin walls, similar to skeletal hyphae in T. foedata. New Zealand collections were taken from eucalypt power poles, bridge decking and railway sleepers, all imported; it is probable that this species has been introduced with this timber.
Recognised readily by the strongly concentrically sulcate surface zoned with alternating bands of tomentum and naked areas, and a thick, coloured cortex. The large pores become irpiciform and towards the centre almost labyrinthiform although remaining alveolar peripherally. Sometimes abhymenial hairs are shed, when the surface appears dark vandyke brown.
[Murrill (1907, p. 467) records Trametes meyenii from the Philippines as a synonym of Coriolus maximus (Mont.) Murr., a species characteristic of tropical America. Lloyd (1917b, p. 724) describes a Cuban collection of Polystictus maximus with cylindrical spores 12 x 4 µm. From this description Coriolus maximus does not appear to be a synonym of Trametes meyenii.]
