Fungi Friday 21st February 2020
The Weald holds so many future Fungi Fridays. It’s an ancient wooded landscape that stretches across Sussex, parts of Surrey and into Kent. It covers the most wooded part of the UK in East Sussex. Once it will have connected with the New Forest, forming much of England’s post-glacial ‘wildwood’. I am very privileged to live within rambling distance of the Weald. I write about walks in it once a month, check that out if you will.
I managed to sneak ninety minutes in locally last week and found plenty of interesting things. As well as the ‘dark side’ of fungi, a reminder that a fungus giveth, and it taketh away.
We have had two storms in two weeks in Sussex and the winter streams are tickling through the woodland understory. Above, a tree was resting in a winterborne. This means a stream that only flows in winter when rainfall is higher. In Ireland, lakes (or loughs) that appear in winter are known as ‘turloughs’. Got plenty of those right now in Brexit-land.
The log was covered in some nice looking turkeytail, a very common polypore that is said have anti-carcinogenic properties. It was a nice way to start.
Then I happened upon these absolute corkers growing on a dead birch tree. These are blushing bracket in their mature stage. This area of the woodland is very wet, with mosses like sphagnum attempting to recolonise more places. It is set in amongst mature beech trees at the edge of heath-ier habitats, largely consumed by pines that were planted, rank and file, by the Forestry Commission in the 20th Century. It’s very wet and many birches are succumbing there. This is natural.
This is a standalone dead birch tree with birch polypore, also known as razorstrop fungus. It’s a tough bracket fungus that people probably once used to sharpen their razors. It naturally controls birch trees and breaks them down for other organisms to devour, and therefore new soils to be created.
Here’s a quick macro of one of the mosses from the work of the razorstrop, looking much like a cedar or a fern.
I found some split gills looking rather shaggy, in a good way. If you look at the yellow smatterings around, I think that’s a slime mould making its way across the surface of the bark.
Rewind to May in this area, when the first leaves were appearing on the trees and the ground was far drier. This is one of my favourite trees to photograph in this woodland because of the orange algae and the beautiful buttresses at the tree’s base.
Here it is in December, the ground much more wet, the leaves all gone. Can you see the bracket fungus at its base? It has been damaged, probably by a visitor testing its strength.
And here it was last week. Evidently the tree has been destabilised by the decay which has been accelerated by the fungus. This has softened the heartwood which leaves the tree vulnerable to storm damage.
But this veteran beech tree still lives, it has only lost one of its three trunks. I hope it can remain where it is and continue down its veteran path into the realm of the ancients.
It’s just another reminder that fungi has its own way in the world and there is no sentimentality involved. It’s there to break down organic matter. Trees were not a safety concern until we started walking underneath them everyday.
Some species share what they can find, others take, take, take. It’s in their nature. But in the end fungi are contributing to vital processes of organic recycling and renewal. Without the ecological role of fungi our species would not exist writing blogs, taking photos, hurling abuse at passers by, or walking under veteran trees in the woods.

Very cool pics!
