Description:Basidiomata branched, initially obconical or obovoid, then campanulate or widely obovoid, 4.2–6 × 3.2–5.5 cm. Base glabrous, with basal branches 5–16 mm thick, white; mycelium inconspicuous, white. Ramification polychotomous in the basal zone, otherwise, usually trichotomous, U- and V-shaped, ramification range 3–6; branches cylindrical, initially densely grouped, then divergent; orange yellow to orange with orange yellow sporeprint. Apices obtuse, short, initially yellow, then concolourous with the branches. Context fibrous, compact, brittle in the branches, homogeneous, concolorous with external surface; taste sour in branches, softer through the base; flavour which reminds one of a rubber eraser. Chemical reactions: FSW (+) bluish green in hymenophore. Generative hyphae without clamps, partially with ampulliform septa up to 15 µm in diameter, with conspicuous granular ornamentation; hyphae of 4–9 µm wide in the trama, with thin to moderately thick walls; hyphae of the mycelium 2–4(–5) µm wide, with thin to moderately thick walls; those of the external part sometimes with amorphous crystalline or granular incrustations. Secretory hyphae in the trama and in the mycelium, the former linear and 2–4 µm wide, the latter acanthodendroid 1.5-3 µm wide. Hyphidia filiform, 2–4 µm wide. Basidia claviform, without basal clamp, (46–)50–73(–80) × (8.5)9–11 µm, with 4 sterigmata. Spores oblong-elliptical, (8.5–)9.5–11.5(–13) × 4–5(–5.5) µm [Lm=10.9 µm, Wm=4.7 µm, Em=2.3]; spore wall thin, yellowish with verrucose ornamentation
