A rare, though recently-described, species reported to form specific mycorrhizal associations with mountain mahogany (Cercocarpus; Rosaceae) in semiarid areas of western North America. This species is proposed for consideration due to its host specificity and limitation to harsh environments.
Originally described from Utah, USA (Boxelder County, Sawtooth National Forest, Raft River Mountains), Mushroom Observer records place the species in Colorado and Montana as well, suggesting the Intermountain West as geographic range.
Restricted to semiarid forests in likely ectomycorrhizal association with Cercocarpus.
