No specimen available

This possible suillelus luridus was discovered on a roadside verge in grass lined with lime trees in the East Midlands, UK.

It has a mushroomy, earthy, porcini-like scent.

The spore print has come through on this specimen and it is indeed olivaceous, snuff-brown.

The cap is 15cm in diameter, sandy ochre-to-dusky brown, tinged red around the edge of the cap. The pores appear yellow to brown, and when cut in half also appeared brown inside. There is some brown reticulation on the stem. The specimen is 10cm tall. There was some difference in colour upon bruising, turning darker.

Upon bisection, the flesh around the inside of the stem turned a pinkish-red colour, and the flesh of the cap and around the edges of the stem turned a distinctive blue-to-navy colour, which has since faded (see picture).

It was found today, August 12, a damp late summer day in England.
