B. Gilled Mushrooms (BOLETACEAE)
Underneath the cap, instead of gills, the boletes have a spore-bearing structure with small pores through which the spores leave.
C. Lurid Bolete (Suillelus luridus)
Under the olive-brown cap are small orange or red pores, which characterise this species. It is ectomycorrhizal and generally found in calcareous soils under beech, oak, or limes. It stains blue when bruised.
