Trunk diameter about 50-60 cm; trama corky; smell indistinctive on rooting wood or earth; 5% KOH reaction on pore and sterile surfaces black; SP very faint, possibly whitish ? - Spores smooth. Dimensions: 5.5 (SD = 0.2) x 3.5 (SD = 0.2) μ, Q = 1.56 (SD = 0.08), n = 30. Olympus CH20, NEA 100x/1.25, magnification 1.000 x, oil. Hymenial setae dimensions 43 (SD = 6.4) x 7.8 (SD = 0.7) μ, n = 29; generative hypha diameter 2.4 (SD = 0.2) μ, n = 6; skeletal hyphae diameter: 3.6 (SD = 0.6) μ, n = 6; setal hypha diameter 8.6 (SD = 0.7) μ, n = 6; NEA 40x/0.65, magnification 400x, in water, congo red.
