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).

Western North America, from the Pacific States of USA; Collections are from southern California into Washington. Photographs of specimens appearing to be X. salicicola also occur from southern British Columbia, Canada.

Being a newly described species, very little in known about population dynamics or trends of this species.

Typically in wet, muddy or hard-packed soil in swampy or riparian areas. Ectomycorrhizal, associated with willow (Salix spp.), Cottonwood (Populus trichocarpa), and occasionally in landscaped areas with ornamental birch (Betula spp.) and Linden (Tilia spp.). Habitat details are still lacking.

None currently identified.
