The language of leaves

Fungi Friday 16th October 2020

I visited the Surrey Hills in the North Downs last week. Autumn was pushing through lots of tree species, but the oak and birch still held green. I was expecting to find more mushrooms, judging by the glut of shrooms splurged across social media in the past week.

This is the moody view from Box Hill, one of southern England’s best known beauty spots. Box Hill is part of the North Downs, a ridge of chalk that runs between Farnham in Surrey to the white (green) cliffs of Dover. The North Downs, like its southern sister, is covered by chalk grassland and woodland habitats, overlooking the clay soils of the Weald which are interlaced with sandy heathland.

I was expecting to see more mushrooms because of the recent rain and the time of year (autumn, FYI). There were a few fly agarics (check out this great thread on Twitter) but not much else. Perhaps London’s famous gangs of illegal foragers had got the train down and taken EVERYTHING.

I don’t think the foraging fyrd had been by, because these parasols were getting ready in the grasslands. Also I don’t know if they even exist to be honest. How it started (above).

How it’s going.

The amanita family were present in the form of what is probably a false-deathcap. The biggest hoard was to be found in an area of woodland, as you might have guessed.

In June I wrote a post about honey fungus and how disliked it is. It’s not really bothered though because it’s grown to be the biggest living organism on/in Earth (I think). This batch of honey fungus is the biggest spread of fungi I, have, ever, seen. The mushrooms are popping up from a widely spread mycelium in the soil.

Looking at the individual mushrooms I think this is ringless honey fungus because it lacks a collar or ring on the stipe.

Then again, looking at another spread growing around an old stump, there do appear to be turtlenecks going on.

My friend Jess was keen to show some love for the honey fungi. The decaying trunk the mushrooms are sprouting from should be a reminder of how important ‘dead’ or decaying wood is in the world.

I am currently reading The Overstory by Richard Powers. I was given it as a birthday present (and funnily enough also passed a copy by Jess) mainly because it’s a novel about trees. It’s a complex, multi-protagonist story that comes together around the clearance of ancient old-growth woodlands in North America. One of the characters is a woodland ecologist who gives evidence in court as to why old-growth woodland should be protected from logging. It’s a brilliant scene, and it has a quote in it which really hit home with me:

“I sometimes wonder whether a tree’s real task on Earth isn’t to bulk itself up in preparation to lying dead on the forest floor for a long time.”

The amount of life found in the decaying tissue of a fallen tree that no longer grows outnumbers that found in living trees. Yet deadwood has been cleared from European temperate woodlands to such an extent (hi Forestry, I know, you’re changing) that many species dependent on this habitat are at risk of extinction.

Honey fungus is just one species that creates deadwood habitat for insects, spiders and other species which depend on it. These deadwood invertebrates are the most threatened species group in Europe. If you can do anything in the space you have, be it a private or a public space, please add some dead wood. It will make more difference than perhaps you realise.

Thanks for reading.

    Another enjoyable post Daniel, and an awesome spread of Armillaria. Iโ€™ve seen some big groups around birches in Sydenham Wells Park, but yours take the cake (biscuit?)โ€ฆ in relation to which, a Polish friend tells me they (the honey fungus, not the cake/biscuits) are eaten in Poland where they are called โ€˜opieล„kaโ€™. I know you have visited eastern Europe a few times โ€“ does this accord with your experience?

      Hi Peter, thanks very much for your comment. Sydenham Hill Wood often has large spreads at stumps, as does Dulwich Park. Sydenham WP is probably very good for fungi I can imagine.

      I know that honey fungus is edible but the English seem wary of it due to potential stomach upsets. The only thing I can say is that Russian Instagram foragers seem to gather it very keenly when it’s young, so another Slavic cultural thing perhaps?

      I will have to ask my Polish and Czech friends! I don’t know many Russian people unfortunately.

      Daniel
