This is one of my favourite mushrooms, not really for eating but mainly because of it’s attractive colours and fantastic commonly used name!

Simply called Plums and Custard (Tricholomopsis rutilans) this very common mushroom almost looks good enough to eat, and even sounds good enough to eat, but before you get too excited, the general consensus is that it’s just not recommended. Too watery, unappealing with a bitter or unpleasant taste. Mind you, I’m not really much a fan of the real dish!

When you first stumble across this mushroom, the first thing you notice is it’s striking purple cap (sometimes with a reddish tinge). On closer inspection you’ll notice that purple effect is made up of many purple/reddish flecks or scales on a predominately yellow cap. They’re are usually denser at the centre, appearing darker. The same colour features on the stem are similar to the cap, but the fine purple scales are less profuse.

On the underside you’ll find the distinctive rich yellow gills, which in my opinion, actually do have an uncanny hue of custard.

The size of this mushroom varies from place to place and can grow quite large. But basically the cap dimaetre ranges from as small as 4cm up to 12cm. I also read somewhere that one specimen at an Italian mushroom show had an unusually large cap of 56cm in diametre. Now that’s big!

Next time you’re out in coniferous woodland during the usual mushroom season (September – November) keep a look out for these beauties growing on or around dead wood or old stumps. Shame we can’t actually eat them. Not for pleasure anyway!

The distinctive purple and yellow colours of the Plums and Custard mushroom.

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!

Featured 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.

Notice the cap has a slight blue colouring and a distinctive bump (or umbo) at the centre which is darker in colour

King Alfred was a terrible cook. In fact (but really in legend) while hiding from the Danes, he’d left a whole batch of cakes in the oven. They were suitably burnt and naturally ruined. So I can only guess he went to the woods and scattered them everywhere on dead ash trees to try and cover up his mistake and pass them off as some kind of fungus. Or something!

King Alfred’s Cakes (Daldinia concentrica) attach themselves on the dead wood of broad leaved trees, mainly ash and beech. It’s one of those distinctive fungi I see every almost every time I’m out in woodland. Although their season is summer to autumn, the older specimens linger on the wood for years and years.

Their appearance is literally that of some burnt cakes or even lumps of smooth charcoal. Older fruit bodies have a shiny surface, but younger developing fruit bodies are red/brown in colour with a duller surface. If you were to cut one open it would reveal silver/light and black concentrical zones (hence the ‘concentrica’ in the scientific name), very similar to the ring zones of a tree – or at least half a tree (due to their hemispherical shape).

Other ‘common’ names for this fungus are Coal Fungus (for obvious reasons) and Cramp Balls because it used in an old folk remedy for night cramps. I think I’d rather have the night cramps!

And as a great bush craft tip, these beauties are great for starting fires! The inner flesh of an old, dry specimen can be lit with a ‘firesteel’ flint for example (or even a magnifying glass). It will slowly smolder, much like your barbecue briquette and can be used to light your tinder.

But needless to say – much like burnt cakes – these fungi are not edible.

This is one  of the common fungus sights around. In fact it is one of the most commonly recorded fungi in Britain. I’m talking of course of the Hairy Stereum or Hairy Curtain Crust (Stereum hirsutum). You’ll find it layered on the dead/fallen wood and stumps of deciduous trees – and it’s appearance is all year round. Shame it’s too tough and leathery to even think about putting in the pan! Damn!

It’s a bracket fungi and has a semicircular shape which is wavy or curtained in appearance. The ‘zoned’ yellow/brown fruiting bodies typically form in many rows, overlapping each other as they go. I think they look quite pretty when in full bloom – especially when there’s a quite a few of them. Each individual cap can grow up to 6 cm in width and can be up to 3mm thick. Older groups of the Hairy Stereum turn green with algae and look like some kind of Martian slime lettuce! (It does!)

So what’s this ‘hairy’ business all about then? Well, on initial viewing you don’t notice, but on closer inspection you can see many hairy tufts along the upper side. And as a bit of extra trivia, hirsutum in latin means hairy. The brighter yellow/orange lower surface, which is smoother, releases the spores. When older, this underside fades to a dull grey/brown.

So to sum up – If you haven’t seen any of these yet – you’re on the wrong planet. And yes – they’re inedible.
