Fungi 🍄: keeping up with the polypores

This week I stumbled across two of the more charismatic polypores you can find at this time of year. Polypores are bracket fungi that grow like shelves, usually from a tree trunk but sometimes also at the base or from a branch.

On a morning walk I went to check on the progress of a polypore I’d spotted several months ago (pictured above in late June 2021!), growing at the base of a large oak tree.

Oak bracket is one I posted about almost exactly a year ago during a visit to Suffolk. It also goes by the name of weeping conk, with a scientific name of Pseudoinonotus dryadeus. It’s a parasitic species, which means that this tree may be suffering some internal, ‘mechanical’ trouble. I hope not because it’s one of the largest in the area and is right next to a path. This makes it much higher up the chopping order if public health might be deemed to be at risk. I will never forget being taught that trees weren’t a hazard until we showed up.

This is a very attractive fungus, if you like a dough that drips caramel. It grows at a fairly critical part of the tree, where it meets the ground. It’s crucial because the tension of the roots holding the trunk upright.

Look into those hundreds of caramel eyes and tell me this is not one of the most beautiful fungi out there.

Later that evening I cycled out to the countryside on what was the end of a September heatwave. The landscape was very dry and smelly. I could smell the manure from my house two miles away in the daytime. That evening I became acquainted with the stench up close – muck spreading in the fields. It was absolutely rank, undoubtedly made far worse by the heat and lack of rain.

My route took me past the 800-year-old Sun Oak. Like the large oak I saw earlier that morning, this tree was also home to a charismatic polypore fungus.

This red button is a beefsteak fungus, Fistulina hepatica. It may also have been a red button – do not press the red button. Unless you want to continue watching this programme (BBC joke).

Oh go on then.

In reality this fungus will grow out to form something that looks like a human bodily organ (hepatica). It’s often on oak or sweet chestnut, especially more mature trees. It’s another parasitic species but it’s said to grow too slowly to ever cause the tree structural problems. We should remember that these fungi have been growing with their hosts for potentially millions of years. It’s the impact we have had on their habitats that have made the trouble. Check yourself before you wreck everything else.

Here’s a recent example that cost me several milligrams in blood as the mosquitos were hanging out under this tree waiting for me to arrive. Beefsteak indeed.

Thanks for reading.

The Sussex Weald: ancient oaks under the stars

Cowdray - 12-2-2019 djg-14

Cowdray Park, West Sussex, South Downs National Park, February 2019

Leaving work at five o’clock in the dark is never nice but it depends how you look at it. Inspired by the Dark Night Skies initiative, I made a stop off on my way home to see some stars. I have been photographing trees in the dark since about 2008, mainly of trees under street lamps in south London. It was something to do in those long, drawn out winter evenings. Since then I have started photographing trees in the daylight, too. Having had the chance to volunteer and work in woodland conservation has taught me a lot about trees and their ecology. Having moved away from practical woodland conservation in the day-to-day sense, though still leading the odd tree walk, I am reveling in photographing some of the trees that are found throughout Sussex. One of the trees I have had the pleasure of spending some time with is the Queen Elizabeth I sessile oak in the South Downs National Park. This tree is completely hollow and has perhaps been around for 1000 years.

Photographing the same tree again and again isn’t always interesting for you or other people. A recent interest in the night sky (the fact I can now see it, being away from a city, rather than knowing anything beyond the moon and the plough) gave me the idea to use the early nightfall to try and photograph this amazingly old tree under the stars.

Cowdray - 13-2-2019 djg-4

The photos were taken with a wide angle lens and a tripod. I used my mobile phone torch to light the tree. The bright light above is the moon, something that plays havoc with night photography due to the fact it outshines many of the stars.

Cowdray - 13-2-2019 hi-res-5

The problem with my phone torch is that it goes off after a while so I had to trot back and forth to keep the light on. In this light the tree looks fleshy and bulbous, quite animal-like I think.

Cowdray - 13-2-2019 djg-7

When the mobile phone torch light did go out, this is how it looked. I like how the branches reach out to the stars and the astronomically-illiterate thought that they might get snagged in them.

Cowdray - 13-2-2019 djg-8

There are many ancient trees at Cowdray Park in West Sussex near Midhurst. It is almost a point of pilgrimage for people who love old trees and feel some kind of emotional connection to the eldest we have left. This oak has lost almost all of its heartwood and has sinewy remnants decaying inside the bark. I love the purple hue in this photo and the way the distortion of the 10mm wide angle lens warps the trees in the background. I love the rawness of the tree in itself and the stars touching the outstretched twigs.

 

Photography: The New Forest, September 2016

I hadn’t managed to visit the New Forest since May, when redstarts sang in the woods and the stitchwort and bluebells flourished under the trees. A lot has changed since then, Britain having voted by 52%-48% to leave the European Union. I am pro-EU and on the morning after the vote took place I felt a degree of sadness that The New Forest voted to leave. Why sadness? The New Forest is one of the EU Habitats Directives Natura 2000 sites which is specially recognised for its importance across the whole of Europe. One of the main barbs of the Leave campaign was that somehow the EU was an attack on individual freedoms, especially of local, unique communities in Britain. I disagree with this. The Natura 2000 website recognises that the New Forest is designated as a Special Area for Conservation because of the role that local people play in managing its habitats:

The quality of the habitats of the New Forest, and the rich diversity of species which they support, is dependent upon the management activities of the various owners and occupiers. Of fundamental importance is the persistence of a pastoral economy based on the existence of Rights of Common. The commoners’ stock, mainly cattle and ponies, roam freely over extensive areas of the New Forest, playing a vital role in keeping open habitats free of scrub and controlling the more aggressive species such as bracken (Pteridium aquilinum) and purple-moor grass (Molinia caerulea), and maintaining the richness and variety of heathland and wood pasture habitats.

Then again, don’t ask me what I think about the antics of the Leave campaign, nor the failures of Jeremy Corbyn and David Cameron in alerting people to the importance that the EU holds/held for the environment. If you’re interested there is a petition asking for the EU environmental protections to be upheld if/when Britain leaves the EU. Yet again our politicians and political system have failed to protect the environment.

The Hampshire and Isle of Wight Wildlife Trust’s Roydon Woods is one of my favourite reserves to visit. It was silent but for a few flocks of blue tit and long-tailed tit, and one of only a few insects I found was this lacewing larvae (Neuroptera). It was carrying this backpack around, what I think is tied together by the downy hairs of leaves, possibly willow or hazel.

Autumn is a special time, though there has been little rain in recent weeks, there were several large bracket fungi to be found. This is a newly emerging chicken of the woods (Laetiporus sulphureus).

The solitude of the New Forest – most areas away from campsites, car parks and cycling routes are largely devoid of visitors during the week – means you can encounter some wonderful things. I looked up to find a roe deer (Capreolus capreolus) watching me, half way between a field and the woods. There is a clear browsing line in the New Forest and very little natural regeneration of trees because deer and other herbivores, generally New Forest ponies and other livestock, are eating the new growth. Chris Packham has recently said that the New Forest is dying because of over-grazing.

It’s not often that you come across a perfect specimen of a mushroom. Fruiting bodies are short-lived and very quickly deteriorate. To find this giant polypore (Meripilus giganteus) was a moment of sheer joy. As I’ve said in my fungi round-up for last year, I don’t pick them, just photograph them. I’m not precious about this nor hyper-critical of mushroom picking, I just prefer that other people and indeed animals can enjoy them. This mushroom was about 2ft in length and just beside the path. I hope others manage to see it before it decays.

Out on Beaulieu Heath it was drizzling and grey. Stonechats were low in the leftovers of gorse, a flock of medium-sized birds flew overhead and down into the heather which I couldn’t identify. Horseflies dive bombed from the woody margins, the sound of their wings is unmistakable and unnerving. They only want one thing. Along a denser edge of trees and scrub a hare burst free, then came a stoat, turning on its heels at lightning speed to return to the cover of bramble. Spotted flycatcher was also a nice sight at the corner of Lodge Heath.

In the Frame Heath Inclosure forestry operations were underway with mature sessile oaks (Quercus patraea) being harvested. I’ve been reading about the Forestry Commission’s attempts to remove broadleaf species like this from the Forest in the 20th century. It took ministerial intervention and local opposition to stop a near complete shift to conifer plantation.

Sitka spruce (Picea sitkensis) is one of the preferred species for foresters. They are shallow rooted trees liable to windthrow in more open landscapes. This spruce had been taken down by just that, a large hole bored through its middle where the soil had fallen away.

The gentle giants of English oak (Quercus robur) are far ‘happier’ standing alone in the landscape. The reason they are not surrounded by regenerating trees is because of the aforementioned grazing taking place around it. Give me these beautiful old trees any day over a spruce or pine monoculture. We should be thankful to all the people who have fought to fend off intrusive forestry practices in the Forest.

It is these ancient and veteran trees that makes the Forest so unique in Europe. The number of these old trees draws the breath, in areas which are not Inclosures where oak, pine or spruce are planted in regimental fashion for timber, there are just so many of them to be found.

Balmerlawn is close to Brockenhurst and hosts two spectacular old English oaks. This one has a trunk about 6ft and I would approximate it to be over 500 years old.

Next door to it is a younger oak with a massive ‘wolf branch’ as arborists call it, reaching out towards the road. Where it swoops closest to the ground there are two patches where the grass has been worn away by kids jumping up and down over the years. It’s a dream to climb.
