Caloboletus radicans, also known as the rooting bolete or whitish bolete, is a large ectomycorrhizal fungus found in Europe under broad-leaved trees, fruiting during the summer and autumn months. It has a pale buff or greyish-white cap, yellow pores and a stout stipe, and stains intensely blue when handled or cut. Bitter and inedible, it can cause severe vomiting and diarrhoea if eaten.
