Notes.

This species is extremely similar to P. neostrigosus in appearance and has been treated as the same species (e. g. Pegler 1983; Li and Bau 2014; Li et al. 2015; Vargas-Isla et al. 2015). However, in our conception, these two species should be considered as two independent species. Panus rudis differed from P. neostrigosus in morphology by shorter metuloids and wider cheilocystidia. Moreover, the phylogenetic analysis results also support this conclusion.
