Boletus fibrillosus, commonly known as the fib king,[2] is a basidiomycete fungus of the genus Boletus. The holotype was collected in Mendocino County, California.[1][3] Phylogenetic analysis has shown it to be a member of a clade (closely related group) with B. pinophilus, B. regineus, B. rex-veris, B. subcaerulescens, and Gastroboletus subalpinus.[4]

The cap is up to 17 centimetres (6+1โ„2 in) wide and buff to brown to dark brown, with a wrinkled to finely fibrous texture.[5] The tubes are yellow, while the flesh is white to buff and does not stain when cut.[5] The stem is up to 16 cm long,[5] yellowish at the top, brown otherwise, with a reticulate texture,[1][3] and mycelium enshrouding the bottom.[6]

The species has only been found in western North America.[5] The fruiting bodies are found in mixed coastal forests in the fall, usually singly or in small groups.[6] It is edible, but considered to have inferior taste to other edible boletes such as B. edulis, which it is often confused with.[7]
