As winter seems to drag on and on, all mushroom foragers seems to be stuck in some kind of ‘no mans land’ of woe and sorrow… Hey ho!

Fomes fomentariusBut many fungi are perennial and more noticeable through the winter months. They’re easier to spot since many trees are bare and no dense foliage can get in your line of sight. And although not edible, they are worth a look. Some have good uses or properties that are quite interesting (probably not everyday use), as you’ll soon discover…

The Hoof Fungus or Tinder Bracket (Fomes fomentarius) is one of these annually persistent sights. This bracket fungus will get most people’s attention as many grow (often in groups) more or less at head height on the host tree (usually birch or beech). They’re also seen on fallen trunks and logs. It’s size is pretty substantial too. Growing up to 25cm in width and height, making it quite hard to miss!

The first thing you will notice is the familiar ‘hoof shape’ with a smooth dark grey upper zone and several layered, concentric zones below. The outer surface (crust) is almost as hard as the wood on which it grows. Go on, give it a tap! The light brown flesh within is very fibrous and quite hard too, smelling very acidic and fruity. A smooth underside shows the small light grey (sometimes light grey/brown) rounded pores, and like the upper concentric zones, the tubes also grow in several layers during the life cycle.

OK, so far this fungus seems to be pretty weird and particularly bland. But here comes the interesting stuff! Over the centuries, this has been a handy piece of nature our ancestors and die-hard survivalists alike have enjoyed to use…

To reconfirm, this bracket fungus is persistent throughout the year and very durable. One key feature is that it does not burn, but simply smolders. A hollowed out Hoof fungus was used to move (or store) burning embers that would keep for days at a time. The other English name ‘Tinder bracket’ is well founded too – When dried, the inner flesh catches a spark quite easily and can burn well – useful as a good ember (see this link for more info). A recent archaeological discovery uncovered a European Iceman who also had a use for this ‘Tinder Bracket’ -See the “Ötzi the Iceman” story here.

The fun doesn’t stop there though! Until relatively recently, a common use in Germany was the craft and creation of hats and bags, using the soft and pliable mycellial core (located inside the top-centre of the fungus). I intend to get a hat myself if they’re still out there, I must!

Just like many other fungi, there are sometimes useful medicinal uses. Centuries ago, Fomes fomentarius was widely used as a styptic to stop bleeding and as a drug to treat wounds. Even today fungi are invaluable in this area. The fascinating world of fungi never ceases to amaze me.

And before I end this post, I’d like to mention that, from general web visitor feedback and personal experience (rather than official research results), I consider this fungus be a ‘common’ species in the UK (more north than south). Several reference books have stated the main habitat to be situated in and around Scotland only, but I have found no end of these throughout Leicestershire and beyond. A recent enquiry to the ‘mushroomdiary.co.uk’ was questioning this very issue with positive ID’s from the Birmingham area. Migration and declination of fungi is a continual event, and local records are sometimes not up to date, and unfortunately there are no records at all from many areas. But on recent personal research, I’ve found that the appearance of this particular fungi is increasing throughout the UK. Which is all good stuff!

This mushroom is one of, if not ‘the‘ most common of all the Waxcaps (known as the Hygrocybes) which I recently discovered on the 30th October. By posting on the first day of November I realise I’ve missed the Halloween deadline (excuse the pun) and I’m sorry. But Halloween ‘is’ the eve of ‘All Saints Day’ – making my error simply forgiven! Or something like that…

Hygrocybe conicaAlthough it has been a relatively bad season for mushrooms and fungi alike due to the dry weather, this last week has proved fruitful, especially in relation to Waxcaps.

Because of the excellent timing, I had to feature the ‘Witch’s Hat’ or ‘Blackening Waxcap’ (Hygrocybe conica) to be my latest post.

As the common and scientific name suggests, the cap of this very common grassland mushroom is ‘conical’ in shape, usually broadly conical or bell-shaped (often irregularly lobed). The texture, common with all Waxcaps, is slimy and waxy and although quite small, is very noticeable in the grass due to it’s bright and striking colours. In this case, the colour can vary somewhat, but mainly you can see yellow/orange (sometimes with scarlet shades) – even hints of green can be present.

But the main feature you will recognise (again, shared with some other Waxcaps), is the ‘blackening’ effect (sounds very seasonal and horrific!). The older the mushroom is – the blacker it will get – although it does not auto-digest and turn to ink like the gills of the Inkcap genus.

Very old specimens turn completely black and appear to be decayed or burnt out. If picked, you will also notice it will bruise black upon handling. But if left alone, the blackening process will slowly take effect, starting mainly from the cap edge (see image above).

Keep a look out this (late) autumn and you may find some along with it’s more colourful friends. It can be found mainly in grassland in fields and woods, but is also common in ornamental lawns, waysides and even plant pots (as my mother discovered!) due to it being less sensitive to nitrogen enriched soil.

It is classed as edible and sometimes as inedible or poisonous from different references. But it is not deadly, and I’m guessing – not very palatable. It’s just best for looking at, which is good because it’s so good looking…

Although present mainly from June through to December this fungus is much more noticeable throughout the winter months, which unfortunately for the mushroom hunter, is well on it’s way! And to note, we have especially had a dry summer/autumn which has robbed us of many wonderful woodland finds, but that’s the way it goes sometimes…

Calocera viscosaThe commonly named Yellow Stagshorn (Calocera viscosa) can be found always growing on dead and rotting coniferous stumps and logs, or appearing to grow from the soil, but this is due to underground rotting wood.

Although this fungus looks suspicious due to its bright yellow colouring, it is in fact harmless. But it’s not really a gourmet treat either! It has a rubbery texture with a ‘non-existent’ flavour. Never mind! But that besides, because of it’s pretty appearance, it is sometimes used to garnish salads and foods.

The Small Stagshorn (Calocera cornea) is a very close relative but much smaller and grows on deciduous rotting wood. Unlike the Yellow Stagshorn it has no forking branchlets at it’s tip but instead tapers out to a single, thin tip.

Look out for Yellow Stagshorn this autumn and winter time. They usually tend to be a grand and pretty decoration to any lone conifer stump…

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.

Razorstrop Fungus

Typical semi-circular/kidney shape of the Birch Polypore

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’.

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!
