BoletarBoletus edulis
Cep / penny bun
A variable species with a broad range of tree associations. Begin with its full description, not a cap-colour shortcut.

European porcini
A shared group, not one uniform appearance. Four European species are a useful starting point in the literature, not a four-way photo quiz.
Educational field guidance only. Boletar does not identify mushrooms or determine edibility.
What the research adds
Kew's porcini overview and Beugelsdijk et al. (2008) discuss B. edulis, B. aereus, B. pinophilus and B. reticulatus. The study supports four lineages while emphasizing variation within B. edulis. It does not offer a reliable one-photo test for casual users.

Bronze bolete
Often discussed for its dark cap. That observation is an introduction to the literature, not a distinguishing rule.

Pine bolete
Tree associations feature in its descriptions. A nearby pine, on its own, does not establish a mushroom's identity.

Summer bolete
Its descriptions draw attention to stem netting. Netting also occurs in other boletes and must not become a shortcut.
