Boletus albobrunnescens is a species of bolete fungus in the family Boletaceae.

It is found in mixed evergreen and deciduous forests of Thailand, where it fruits singly to scattered in soil under Pinus and Castanopsis trees.

Its fruit bodies have caps measuring 5.5–11 cm (2.2–4.3 in) in diameter.

The top of the stipe has a prominent network pattern (reticulations) that diminishes as it extends down to over half its length.

The smooth spores are roughly spindle-shaped (fusoid), and measure 10.5–11.9 by 4.2–4.9 μm.
