B. lignicola

Buchwaldoboletus Pil?t

Two species are known in Europe. Saprotrophic on dead wood of conifers, one species probably mycoparasite on Phaeolus schweinitzii. Fruitbody boletoid. Cap dry. Pores and tubes yellow to olivaceous yellow. Flesh whitish or yellowish, unchanging or blueing slightly.

Buchwaldoboletus lignicola (Kallenb.) Pil?t

Description

Cap up to 10 cm, at first hemispherical then expanding to convex, ochraceous, beige or light brown, velvety, distinctly dry even in wet weather, unchanging when bruised; cap margin inrolled for a long time. Stipe cylindrical or spindle-shaped, usually tapering towards the base, mostly concolorous with the cap, but sometimes yellow in the upper parts. Flesh yellowish, slightly blueing above the tubes. Tubes at first bright yellow, then olivaceous yellow, unchanging when exposed to air. Pores bright yellow, unchanging when bruised. Smell not distinctive. Taste not distinctive. Spores 6.5–10.5 ? 3–4.5 ?m.

Habitat. Coniferous forests, associated with dead stumps of pines (Pinus), larch (Larix) and Douglas fir (Pseudotsuga); probably also a mycoparasite on Phaeolus schweinitzii.

Distribution. Widespread in Europe, but rare throughout.

Similarity. Xerocomus badius also grows sometimes on dead hardwood. It is however distinguished by the viscid cap cuticle and differently coloured fruitbodies.
