Sarcodon quercinofibulatus

Ciri dan struktur

The cap is 6–14 cm broad, initially convex then flattening with a low, sometimes indistinct central bump (umbo. Its surface slips free from the flesh and breaks into coarse, concentric scales that are brown to grey‑brown, darker or almost black towards the centre. The margin is smooth, incurved and finely striate. Beneath the cap, the hymenophore (the fertile, spore-bering surface) bears short, decurrent spines ("teeth") 5–8 mm long, pale cream when young, becoming grey‑brown in maturity. The stipe is 5–8 cm tall by 1–1.5 cm thick, club‑shaped, initially cream‑coloured but ageing to grey‑brown, and carries a few scattered spines near the apex. The flesh is firm, cream‑white, slowly greying on exposure, with a faintly bitter taste and a mild fungoid odour. In contact with 10 % KOH it turns greyish‑green. Microscopically, the spores are broadly egg‑shaped to roughly spherical (globose), finely tuberculate, measuring 6.5–7.4 by 5.4–6.4 micrometres (μm) (average 7.0 by 5.9 μm). The basidia are 30–40 by 8–10 μm and mostly bear four spores. Clamp connections — small hook‑like hyphal structures involved in cell division — are abundant on all tissues, including the cap cuticle, spines and stipe trama. The hyphal system is monomitic, meaning it contains only generative hyphae.

Habitat dan peran ekologis

This species is strictly ectomycorrhizal with sessile oak, downy oak and European beech, fruiting on the forest floor of pure deciduous stands of sessile oak and Italian maple. The soil at the type locality is slightly acidic (pH ≈ 6.7) at 400 m elevation. Fruiting occurs in summer and early autumn (July–September). All known collections come from north‑eastern Catalonia: five gatherings under sessile oak at La Vall de Bianya (400 m) between 2007 and 2010, and a single autumn 2010 record from mixed beech–oak woodland near Rupit (1000 m) in the El Vilar de Pruit area (Osona).
