Pileus 4.5-8 cm broad, convex to plano-convex, surface dry, tomentose then cracked into subpyramidal floccose scales, dull crimson to rose pink, fading to pale fawn in age, margin stellate with remnants of false veil. Context 7-1.1 mm thick in the centre of the pileus, yellowish, soft, quickly change to blue when cut or bruised. Tubes 7-14 mm thick, strongly depressed at stipe, yellow, becoming olivaceous brown in age. Pores angular, 1-2 mm broad, yellow to brownish pink, quickly cyanescent when bruised. Stipe 5-10 cm long, 0.8-1.3 cm thick, solid, subcylindric, with whitish mycelium around enlarged base, surface fibrous, fading fuscous from the base upwards and apex yellowish. Spore print olivaceous brown. Spores 22-24 × 12-13.5 μm, boletoid elliptical with longitudinal oblique striae. Sterigmata 2-4, 6 μm long. Cystidia 62-95 × 17-19 μm, ventricose with a subcylindric appendage or obtuse apex. Tube trama of phylloporoid type.

Note：
Boletellus ananas may be mistaken for old and discoloured specimens of B. emodensis. But the former has pale fruits-bodies from the outset on field-studies, and ridges on spore surface are rather coarsely striate. Apiculus 1 μm long longer than the latter (0.2-0.3 μm) is another distinction.
