Xerocomellus salicicola is a recently described member of the X. ‘chrysenteron’ complex from western North America.

More information is needed on range, habitat limitations and populations. At current time, we recommend listing it as Data Deficient (DD).


Taxonomic notes

Xerocomellus salicicola is a recently described species (Frank et al. 2020). Older records would have been made under the name Xerocomellus (or Boletus) chrysenteron.

More information is needed on range, habitat limitations and populations. At current time, we recommend listing it as Data Deficient (DD).


Geographic range

Distribution is still poorly known; currently known from disjunct populations from southern California into Washington. Photographs of specimens appearing to be Xerocomellus salicicola from southern British Columbia, Canada are posted online (iNaturalist 2021).


Population and Trends

Being a newly described species, very little in known about population dynamics or trends of this species. The habitat it occurs is stable across much of the range.

Population Trend: Uncertain
