Assessment Notes
Justification
Xerocomellus atropurpureus is a common and widespread bolete in western North America. It occurs in a wide variety of habitat types, from young to mature forests, associating with both conifers and hardwoods. No decline has been observed. We recommend it should be listed as Least Concern (LC).
Taxonomic notes
Xerocomellus atropurpureus was a ‘cryptic species’ hiding under the epithet Xerocomellus (Boletus) zelleri. It was recently described as a distinct species (Frank et al. 2020), and is far more common and widespread than X. zelleri.
