DBA45381556153EEB27424D9DC6E50DE.taxon	description	Description. Basidiomata. Annual, resupinate, amorphous, closely adnate on substrate, widely effused, easily separable, cartilaginous to gelatinous, white to cream, sometimes semi-transparent when fresh, up to 12 cm diam and 0.05 cm thick, distinctly shrinking to a film and becoming fawn to clay-buff when dry. Hyphal structure. Hyphal system monomitic; hyphae simple or branched, sometimes flexuous, hyaline, thin-walled or thick-walled, without clamp connections, 2.6 – 3.8 µm diam., embedded in hymenium and subhymenium. Hymenium. Cystidia absent; hyphidia (dikaryophyses) present, unbranched, with several simple septa, usually derived from the same hyphae with probasidia; probasidia pyriform to subglobose; mature basidia thin-walled, obovate to subglobose, 12 – 16.8 × 9.8 – 13.7 μm, longitudinally septate, 4 - celled, usually with oil drops; sterigmata up to 52.7 μm long, 1.4 – 2.7 μm diam., with tapered apex. Basidiospores. Hyaline, thin-walled, smooth, broadly ellipsoid to ovoid, apiculate, usually with several large oil drops, (7.9 –) 8.6 – 9.9 (– 11.1) × (5.1 –) 5.8 – 7.6 (– 8.3) μm, L = 9.2 μm, W = 6.8 μm, Q = 1.35 (n = 40 / 1).	en	Dong, Jia-Hui, Zhang, Xin, Guan, Qian-Xin, Wu, Fang (2025): Morphological characteristics and phylogenetic analysis reveal Helvellosebacina filicata sp. nov. and Sebacina aciculicola sp. nov. in Sebacinales from southwest China.

94663D0A665A59D89E4CE26BAB46B742.taxon	description	Description. Basidiomata. Annual, resupinate, closely adnate on substrate, widely effused, not easily separable, coriaceous, white to cream when fresh, up to 15 cm diam and 0.1 cm thick, color and structure almost unchanged when dry; margin gradually thinning out, concolorous with the center. Hyphal structure.
