描述原文：
Basidiomata annual, centrally to laterally stipitate, soft to hard corky. Pileus single, suborbicular to flabelliform, up to 6.5 cm diam and 1.6 cm thick. Pileal surface dark brown to ferruginous when dry, dull, glabrous, with obvious concentric furrows and strong radial wrinkles; margin obtuse, entire, wavy and incurved when dry. Pore surface pale white when fresh, colour changing to blood red when bruised, then quickly darkening; pores sinuate, 2–3 per mm; dissepiments thin, entire. Context straw colour to cinnamon, with pale white lines, soft corky, up to 7 mm thick. Tubes cinnamon, woody hard, up to 9 mm long. Stipe concolorous with pileal surface, cylindrical and flexuous, up to 6 cm long and 1.5 cm diam. Hyphal system trimitic; generative hyphae with clamp connections, all hyphae IKI–, CB+; tissues darkening in KOH. Generative hyphae in context colourless, thin-walled, 2–4 μm diam; skeletal hyphae in context pale yellow, thick-walled with a wide to narrow lumen or subsolid, arboriform branched and flexuous, 3–6 μm diam; binding hyphae colourless to pale yellow, subsolid, branched and flexuous, 1–2 μm diam. Generative hyphae in tubes colourless, up to 3 μm diam; skeletal hyphae in tubes colourless to pale yellow, thick-walled with a wide to narrow lumen or subsolid, arboriform branched and flexuous, up to 5 μm diam; binding hyphae in tubes pale yellow, subsolid, branched and flexuous, 1–2 μm diam. Pileal cover composed of clamped generative hyphae, thin- to thick-walled, apical cells clavate, faintly inflated, pale yellowish brown, about 50–70 × 4–6 μm, forming an irregular palisade. Cystidia or cystidioles absent. Basidia barrel-shaped to clavate, colourless, thin-walled, 25–33 × 15–19 μm; basidioles in shape similar to basidia, colourless, thin-walled, 23–28 × 13–16 μm. Basidiospores broadly ellipsoid to ellipsoid, pale yellow to yellowish brown, IKI–, CB+, with double and slightly thick walls, exospore wall smooth, endospore wall with conspicuous spinules, (12.3–)12.5–13.7(–14.3) × 9.1–10.8(–11.1) μm, L = 13.07 μm, W = 10.08 μm, Q = 1.3 (n = 60/1). Under SEM, exospore wall uneven, with distinctly circular hollows, endospore wall with long and thick columnar spinules tightly arranged. Notes — Sanguinoderma sinuosum was collected from Australia. It is characterized by its sinuate pores with thin dissepiments, large and broadly ellipsoid to ellipsoid basidiospores. Sanguinoderma sinuosum is similar to S. rude by the dark brown and corky pileus with concentric furrows and radial wrinkles, but S. rude has subcircular pores with slightly thick dissepiments, and smaller basidiospores (9.5–12.5 × 8–10.7 μm) with short and slightly thick columnar endospore spinules (Fig. 8o–p). In the phylogenetic analyses, these two species nested in two lineages with good support (Fig. 1, 2)
