An edible and tasty member of the bolete family, care must be taken when harvesting this mushroom as some of its look-a-likes are toxic.

Yellow but covered in tiny red dots. When cut in half the stem to turn dark blue to black almost instantly. The whole flesh of the mushroom will undergo this colour change when damaged.

Uses

In food

In my opinion they are right up there with the Penny Bun (Boletus Edulis) they have a deep fungal flavour and a lovely firm texture. They can cause gastric upset when raw so must be thoroughly cooked therefore making them unsuitable for drying.

The flesh will turn blue to black when they are damaged but it will go back to creamy yellow when they are cooked.

Harvesting       

This is not a beginners mushrooms as it breaks the rule that we teach beginners when identifying boletes which is “red or blue will make you spew”

They are often found growing in the same places as Penny Buns (Boletus Edulis)


Known hazards

Tasty for most but they can cause gastric issues in roughly 1 out of 5 people.


Potential lookalikes

The Lurid Bolete (Suillellus Luridus) and the Devils Bolete (Boletus Satanas) both do look similar but they both have a red mesh on the stem, unlike the red dots on the Scarletina.

The Deceiving bolete (Boletus Queletii) also has dots on the stem but they are yellow to buff in colour not red. Confusing the two would be a harmless mistake as it’s also edible after cooking and is also very tasty.
