Suillus quiescens [SEP] Introduction
Suillus quiescens is a pored mushroom of the genus "Suillus" in the family Suillaceae. First collected in 2002 on Santa Cruz Island off the coast of California, in association with Bishop Pine ("Pinus muricata"), the species was scientifically described and named in 2010. In addition to its distribution in coastal California, it was also found forming ectomycorrhizae with the roots of pine seedlings in the eastern Sierra Nevada, coastal Oregon, and the southern Cascade Mountains. It resembles "Suillus brevipes", but can be distinguished from that species by its paler-colored immature cap and by the tiny colored glands on the stipe that darken with age.
