Suillus quiescens

Suillus quiescens is a pored mushroom in the genus Suillus (family Suillaceae) that forms ectomycorrhizae with pines. It was first collected in 2002 on Santa Cruz Island off the coast of California in association with bishop pine (Pinus muricata), and was formally described in 2010. The species has been recorded from coastal and montane sites in California and Oregon, and has also been introduced to New Zealand in association with non-native Monterey pine (Pinus radiata). It may be under-reported because it can persist in soil as a dormant spore bank, and because it can be mistaken for the look-alike Suillus brevipes. Although similar in general appearance, it can be distinguished by its paler immature cap and by the tiny glandular dots on the stipe that darken with age. The species is assessed as least concern on the IUCN Red List.
