Notes.

In our phylogenetic analysis (Fig. 1 View Figure 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).
