Description:Trametes hemitephra (Berk.) comb. nov.
Polyporus hemitephrus Berk., Fl. N. Zeal. 2 (1855) 179. - Fomes hemitephrus (Berk.) Cooke; Teixeira, Rickia 1 (1962) 78. - Fomitopsis hemitephrus (Berk.) G. H. Cunn., N.Z.D.S.I.R., Plant Dis. Bull. 76 (1948) 2; Ryvarden, Norw. J. Bot. 24 (1977) 213. -Heterobasidion hemitephrum (Berk.) G.H. Cunn. (1965) 147.
The following is a summary of Cunningham's description (1965) along with some notes that I made from a specimen that he sent to me and which is cited by him, namely Herb. Plant Dis. Div. N.Z. n. 6404.
Pileus -12 cm radius, sessile, broadly attached, applanate or ungulate, finely tomentose then glabrous, sulcate, ochraceous or fawn with greyish zones, then brown to fuscous umber or blackish. Tubes in many indistinct layers; pores 50150ym wide, white of stramineous. Flesh -15 mm thick, cream-colour to isabelline; crust -1 mm thick, woody, brittle, chestnut brown with an orange zone beneath. Spores 4-6 x 2-2.5 µm. Hyphae trimitic, clamped, not encrusted, not dextrinoid; skeletals 3.5-5 µm wide with thick glassy walls, aseptate, unbranched, unlimited, scarcely swelling in potash; binding hyphae 1-3 µm wide, rather scarce in the flesh, abundant in the dissepiments. Surface of pileus anoderm, agglutinated into the crust, not or scarcely encrusted. Causing a white rot.
Cunningham considered the tissue of the pileus to be dimitic without clamps, but I agree with Teixeira and Ryvarden that it is typically trimitic. Teixeira gives the skeletals as of limited growth with many ends in the flesh, but this may refer to periodic terminations of marginal growth in the perennial pilei.
