SFC 20230908-13 (dried specimen) .</p><p>Etymology.</p><p>From orientalis – eastern in Latin, referring to the eastern origin of the species.</p><p>Description.</p><p>Basidiomata fully resupinate, attached firmly to the substrate, young basidiomata growing on stems of shrubs and dead branches, encrusting everywhere when old, forming thin patches on the substrate. Surface smooth, dull, white (1 A 1) to yellowish white (4 A 2), consistency wax-like, cartilaginous. Margin irregularly thinning out and distinctly bounded. Basal hyphal system monomitic, subicular hyphae thick-walled, septate with frequent branching, hyaline, without clamp connections, 3.0–4.3 μm thick. Basidiospores elliptical or allantoid, hyaline, smooth, IKI-, CB-, (7.1 –) 9.0–11.6 (– 12.6) × (5.8 –) 6.1–7.6 (– 8.5) μm with granular contents (L = 10.3 μm, W = 7.1 μm, Q = 1.4, n = 31 / 2). Resting spores usually observed, thick-walled, irregularly shaped. Dikaryophyses coralloid, flagelliformed, and tinily ramified, derived from the same hyphae with basidia. Probasidia globose to subglobose, mature basidia elliptical or pyriform, longitudinally septate, 13.1–17.3 × 7.5–11.8 μm, usually containing oil drops, with elongated four sterigmata, average 2.5 μm width, up to 16.0 μm long, blunt at the apex.
