Neodonkiella Y. Xu & C. L. Zhao 2025, gen. nov.

Neodonkiella Y. Xu & C. L. Zhao gen. nov. Type species. Neodonkiella yinjiangensis Y. Xu & C. L. Zhao. Etymology. Neodonkiella (Lat.): “ Neo ” and “ donkiella ” refer to the new genus’s molecular systematic similarity to the genus Donkiella. Description. Basidiomata annual, resupinate, adnate, soft coriaceous. Hymenial surface smooth, white to pale cream. Hyphal system monomitic; generative hyphae with both simple septa and clamp connections, colorless. Subicular hyphae colorless, thick-walled. Crystals abundant, crowded at hymenial layer and subiculum. Leptocystidia numerous in the hymenium. Cystidioles absent. Basidia clavate, thin-walled, 4 - sterigmate. Basidiospores ellipsoid, colorless, thin-walled, smooth, IKI –, CB –. Notes. In our phylogenetic analysis (Fig. 1), the new genus Neodonkiella was identified as a monophyletic group typified by P. yinjiangensis. The new taxon Neodonkiella falls within the family Phanerochaetaceae (Polyporales) and is closely related to the genus Donkiella. Donkiella is distinguished from Neodonkiella by its generative hyphae with simple septa only (Dong et al. 2024).
