The Bay Bolete (Imleria badia) is a popular and widely distributed edible mushroom found throughout the UK and Europe. It grows in woodland soil, particularly in association with pine, spruce and other conifers, although it can also appear near deciduous trees. Bay Boletes are most commonly found from late summer through autumn and often appear after warm rain. They are considered one of the more reliable edible boletes for beginners once the key identification features are understood.

Bay Bolete is valued for its pleasant, mild flavour and firm texture, making it an excellent addition to a wide range of dishes. Unlike Porcini, it tends to bruise blue when cut or handled, but this colour change is harmless. Because it shares habitat with both edible and toxic boletes, careful identification is still essential. When confidently identified and harvested fresh, the Bay Bolete is regarded as one of the best wild edible mushrooms available to UK foragers.
