Pileus can approach 10 cm in diameter, convex with a conic umbo, dry, but subviscid at margin, finely tomentose to finely subvelutinous, broadly and shallowly pitted (rugulose-reticulate: Corner), even at margin, red overall when young, pale grayish with some red in pits and toward margin. Flesh pale yellow, mostly unchanging, but with some pale blue above tubes near margin of cap, with mild odor and taste. Tubes adnexed to deeply depressed, yellow (2A5-2B5), unchanging, greenish yellow (2C5) with age; pores concolorous, a darker greenish yellow when bruised. Stipe 20 cm long, 12-14 mm broad at apex, slightly broader toward base (3 cm), dry, pink at apex, brownish red overall when young, pale rhubarb red in spots below but otherwise pale grayish tan above and more brownish gray below with age, with white mycelium at base, heavily pruinose overlaying a subtle reticulate ridging at apex, obscurely ridged becoming even toward base, with interior pale yellow, erratically bluing or not.

Other Heimioporus species with a conico-umbonate pileus are not red. Heimioporus kinabaluensis has a similar overall morphology but is differently colored.
