Pallid Bolete

Boletus pallidus



Pale cream to buff cap; stalk pale cream to buff; pores pale cream-yellow. Grows singly or in groups of up to several, on the ground in oak woods. June–September. Cap convex, becoming flat; pale cream to buff; texture dull, dry, suedelike. Pores small; circular, becoming angular; pale cream-yellow, sometimes weakly bruising blue, then brownish. Stalk enlarging slightly toward the base; pale cream-buff, can be reddish at the base; texture smooth. Spore print olive brown. Spores magnified are barely spindle-shaped. The name "pallid bolete" is fitting, as this mushroom is mostly pale cream-buff to very pale yellow.

Lookalikes: Other Boletus species.


Cap width: 1½–6 inches; stalk length: 2–4¾ inches; stalk width: ½–1¼ inches.

Life cycle

This species is mycorrhizal: It exists most of the time as a network of cells (mycelium) connected to tree roots, in a symbiotic relationship with the tree. (Many trees fare poorly without their fungal partners.) When ready to reproduce, the mycelium sends up the mushroom aboveground—this is the reproductive structure. In boletes, spores are produced in the pores under the cap and are released to begin new mycelia elsewhere. The mycelium of a mushroom can live for decades.

Human connections

Some say the flavor of the pallid bolete rivals that of the prized “king bolete” or porcini, Boletus edulis, which does not grow in Missouri. Pick young, firm specimens for using fresh. Older specimens are best dried.

Ecosystem connections

This is one of many fungus species that help nourish forest trees through symbiosis. The netlike fibers of the fungus cover the surface of a tree’s roots, increasing the surface area and the roots’ ability to absorb water and nutrients. In return, the tree shares nutrients with the fungus.
