There are mixed reports on the frequency of this following mushroom. Some reports and publications label this as a common European mushroom, and others regard it as a rare sighting. But whatever the current reality is, I do hope you find one of these. They’re a really beautiful example of how nature, especially the world of fungi, can make things all the more colourful for everyone.
OK, so I’m being a little melodramatic, but the Ruby Bolete (Boletus rubellus or Xerocomus rubellus) is a very striking and pretty mushroom. I actually discovered this last august but I thought it was about time I shared it with the world.
Please excuse the poor picture examples shown here. They had been nibbled and trampled by God knows what! But at least you can see the basics and the beautiful red colour of the cap.
So, whether rare, common or whatever – the usual season for this Bolete (and most other Boletes in general) is from July to November.
It’s a relatively small Bolete in comparison to others of the same genus. The cap ranges in width from 3 – 7cm (sometimes slightly larger), but obviously it’s most striking feature is it’s colour of ruby red and/or scarlet. There also maybe tints of olive colouring near the margin. You’ll also notice there is not much colour change in the pale yellow flesh from the pictures – but there is a colour change on the underside (ie. the pores).
As with all Boletes, there are no typical mushroom ‘gills’ to speak of. They have pores (the open holes from the tubes within the cap). They appear to be maze-like and/or angular and be small and condensed together or quite large and spaced out. In this case it is the latter with the added feature in which it slowly ‘bruises’ blue. Press your thumb on the pores and see the colour change before your eyes. Great and weird all at the same time.
If the red cap and blue staining isn’t enough for positive ID, then take a look at the stem which is slender, often quite tall (up to 8cm), coloured yellow/orange with streaks of red. It is more chrome yellow at the top and duller towards the base. If you slice it in half (vertically) you’ll see the flesh at the base to be speckled with orange flecks. Colour all the way!!
They are edible but unfortunately not really that good. Perhaps younger specimens in a mixed mushroom dish might work, but I gave this batch a miss this time. Too nibbled and mashed!
You can find these special little gems in damper areas around broad-leaved trees in grassland, including local parks. Try to get there before the slug munchers though, unlike me!
Note: This has also been known as: Boletus versicolor, a name that is no longer used.
