Although this is a very common species of mushroom, I don’t come across them that often. Even though mainly white in colour they always seem to be hiding under bracken or disguise themselves in similar woodland undergrowth.

Collybia maculataBut once seen, never forgotten, the Spotted Toughshank (Collybia maculata) is a nice looking, creamy white, chocolate sprinkled mushroom. Although I should really say Toadstool as it is inedible (tough and bitter) and there really isn’t any chocolate involved! If only…

I found this lovely group of ‘toughshanks’ (common name for the Collybia genus) in some mixed woodland, near the edge of a grassy woodland path hiding in the undergrowth. They can be found in both deciduous and coniferous woodland but they tend to favour coniferous trees – like this group.

The caps are initially a clean (slightly creamy) white colour, but soon distinguish themselves with the characteristic of having brown spots or freckles on the cap. These tan brown spots can sometimes merge or not be as contrasty against the white cap, so it may sometimes appear as one blended brown patch, especially at the centre. When younger the caps are dome shaped but flatten out with age and sometimes get wavy at the edges.

On the underside the crowded gills (free from the stem) are also white and, in a similar fashion to the cap, become spotted dark brown with age.

The stem is also a great identification marker too. As with all Collybia species, the ‘shank’ is tough, fibrous and flexible. None of this genus have rings present either. As you see in the pictures they can also grow quite tall (up to 12cm), markings are similar to the cap, but mainly white and the longer stems can sometimes be slightly routing.

So be on the lookout anytime this summer to late autumn. They’re out there, but also like to to hide! See the extra ID notes below for further information…

It’s very rare that I do not see one of these bracket fungus when I’m out and about on a forage. They grow quite large and are around all year. It would be hard to miss one.

The Birch Polypore or Razorstrop fungus (Piptoporus betulinus) is an extremely common polypore fungus. As the name suggests, it is found exclusively on birch trees.

At maturity they are typically semicircular or kidney shaped as they grow outwards from the tree body. Shapes and sizes may differ a little but generally this is the norm. As I mentioned earlier, they can grow to a good size – between 20 – 30cm across and 8cm thick! They’re quite a sight to behold when they get to this size.

The colour is that of pure white (when younger) and as it matures it changes to a dull grey or tawny brown. It’s smooth surface often cracks, showing white flesh underneath. The consistency is spongy or slightly rubbery to the touch. These fruiting bodies can usually last from one year into the next, that is why you can see them all of the time over the winter months.

On the underside the pored surface is smooth and pure white, but over time this gets marked with dark patches from age and/or insect attack.

I know what you’re thinking though. Is this fungus edible? Well, unfortunately not. It actually smells quite pleasant but it’s taste is quite bitter. It’s a shame, I know.

At least it had it’s uses even as far back as 5,300 years ago! In 1991 “Ötzi the Iceman”  (Europe’s oldest natural human mummy) was discovered by German tourists in the Alps. Found in his possession were two species of polypore mushroom. One of which was the Birch Polypore (for medicinal use) which is known to have antibacterial properties. It could have also have been used to sharpen blades or tools – hence the name ‘Razorstrop’.

This is the first in my posts aimed at the Pluteus genera of mushrooms. Nearly always found on rotting wood including logs, stumps and general wood debris, hence the savvy title. The common name used for this group is ”Shield”, and a very apt name it is too because they always remind me of actual shields – fancy that!

Pluteus salicinusFeatured this time is the Willow Shield (Pluteus salicinous). I almost missed several of these on a walk through the woods. The upper canopy had drained quite a lot of the natural light. It was also still dry out there as the recent weather hadn’t delivered much rain – but plenty of sticky warm days!

Perhaps the warmth and dryness had taken the moisture out of these beauties, the wrinkled edges in the photos aren’t usually a common feature of a healthy young specimen.

Imperfections aside, the Willow Shield is a pretty dull mushroom anyway – but on closer inspection really quite distinct. The first thing that struck me was the colour of the cap. Although it appears a mundane grey in these photos (better captured in image below) there is an overall tint of blue (sometimes green) but very subtle, and that really caught my attention. It’s sometimes hard to capture in a photograph, but part of that may be a trick of light and what angle you view it from – or do I need another camera!?

The cap holds further details for inspection. It is noticeably darker at the centre, and after flattening out as it matures it usually leaves a slight umbo (or bump). This central point is very finely velvety to the touch where subtle coloured streaks radiate outwards from it’s centre. The stem itself is a good old ‘uncomplicated’ smooth white (although sometimes with a darker tinge at it’s base).

As with all Pluteus mushrooms, their gills are free from the stem and the spore print will be pink. As this mushroom ages, it’s gills will turn from white to pink as the spores mature.

And last but not least you’ve probably noticed I have categorised this post in ‘What’s your Poison?’ and ‘Tales of Toadstools / The Inedibles!’ because this mushroom is generally classed as inedible. But I have read elsewhere that unlike other Pluteus species, this mushroom (or now should I say toadstool!?) contains small amounts of psilocybin (compound psilocin). This is the same substance found in Magic Mushrooms (or Liberty Caps). So it’s advisable to leave this toadstool alone.

There’s mixed feedback 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 truth 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.

Nibbled red bolete MushroomOK, 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!

Nerd note: This has also been known as: Boletus versicolor, a name that is no longer used.

The summer days so far have been a concoction of a few showery spells, the odd storm and quite a few blazing hot stretches. So even though it has been drier out there in the woods I still venture out. And today I was happy to find a great Bolete specimen.

Boletus badiusThe Bay Bolete (Boletus badius or Xerocomus badius) is one of the more common Boletes and fortunately one of the more tasty ones too. It can be found in all kinds of mixed woodland and has a season from July to November. So I was extra to happy to find one relatively early in the season.

Confusion with Cep or Penny Bun (Boletus edulus) and even the Suede Bolete (Boletus subtomentosus) is understandable, but the Cep’s pores do not turn blue/green on handling. The Suede Bolete does have blueing, but the velvety feel of the cap differs to the smoothness of the Bay Bolete.

Appearances (especially in size) can differ greatly from one Bay Bolete to another – Where they grow is one factor to consider. At first glance they look uncannily like Ceps when growing amongst pine needles on the woodland floor. When found growing in tall grass, they tend to have thinner and/or longer stems (and sometimes a slightly viscid cap) – just like this one here…

The cap can range in size from 4 – 14cm in width, the specimen shown here was roughly 11cm and was a lovely ochre brown colour, smooth to the touch but slightly sticky when wet. It’s stem which is streaked with the same colour as the cap, is cylindrical and smooth. It can grow up to 12.5cm and the thickness can range from 0.8 – 4cm.

Don’t miss out on the chance to grab a few as they’re great mushrooms to eat. It has a pleasant mushroom-like taste (smells mildly mushroomy too), and are especially more palatable when younger as the flesh is firmer. They are also good for drying too.

I’m sure more and more will pop up as the mushroom season starts to kick in. Enjoy…
