Known distribution.

Northern China ( Shanxi Province), Europe, and North America ( Halling et al. 2004; Wu et al. 2014; Xu et al. 2021; Mao et al. 2023); probably southwestern China ( Yunnan Province) (Fig. 1 ).

Notes.

Chalciporus piperatus was originally described from Europe ( Bataille 1908). It was also reported from Shanxi Province, northern China ( Mao et al. 2023). Illustrations and a full description of the species have been provided by Moser (1983), Alessio (1985), Muñoz (2005), Šutara et al. (2009), and Mao et al. (2023). It should be noted that C. pseudopiperatus , described from Europe, has been considered morphologically close to C. piperatus and remains poorly separated based on macroscopic features ( Klofac and Krisai-Greilhuber 2020). Although molecular data for C. pseudopiperatus exist, its phylogenetic position and taxonomic status have not been fully resolved, and it has been suggested that the species may be more widespread in Europe. Future studies including type and additional European materials will be essential to clarify the relationship between C. piperatus and C. pseudopiperatus .
