Archaeologists Found a 10,000-Year-Old Fire Kit Made From Fungi

Your lighter runs out of gas. Your matches are damp. That creeping panic — how do I make fire? — is one of the most human feelings there is. Hunter-gatherers at a Yorkshire lake around 9,000 BC felt exactly the same way. They had a solution in their kit. It was a fungus — and archaeologist Harry K. Robson's 2018 analysis of the Star Carr assemblage reveals just how deliberate that choice really was.

The Find That Almost Got Ignored

Star Carr in North Yorkshire is already famous — it's produced Britain's oldest known house, red deer antler headdresses, and worked bone and flint. But bracket fungi barely made the footnotes. When the site was first excavated in the 1950s, botanist E.J.H. Corner identified some specimens and suggested tinder use. The director noted it in a single paragraph. For decades, that was the whole story. Fresh excavations from 2006 to 2015 changed everything — pulling into focus an assemblage of 82 fungi, most burnt, many deliberately processed, preserved in peat for ten millennia.

Why Did Mesolithic People Carry Fungi?

The short answer: because Fomes fomentarius is one of the most reliable fire-starters in northern Europe's forests. Its hard outer crust makes it durable to carry. Its inner flesh, once prepared, holds a smoulder long enough to transport between camps. Ethnographic records from indigenous groups in British Columbia document people carrying smouldering polypore flesh inside birch bark rolls for exactly this purpose. The species distribution at Star Carr makes the intentionality unmistakable — 76 of 78 identified specimens (97.4%) are Fomes fomentarius. Someone was selecting for it, specifically, repeatedly.

How Did They Actually Turn a Mushroom Into Fire?

The process demands real craft knowledge. Strip the hard grey crust. Remove the spore tubes. Soak or boil the remaining flesh for hours, then pound it with a smooth stone until it's nearly leather-like. Dry it carefully — too much heat hardens it. Char the surface slightly so it's primed to catch a spark. When flint strikes iron pyrite, the spark lands on the amadou, which smoulders. Transfer that smoulder to a dry grass bundle and blow it into flame. These people weren't improvising. They were running a system.

What the Burnt and Sliced Specimens Tell Us

Of the 81 recently excavated specimens, 54 show clear modification — outer surfaces stripped, interior flesh removed in strips, brackets reduced to their usable core. Forty-one are charred, ranging from lightly scorched to fully carbonised. One has two clear incision marks. Only one specimen was found still attached to a tree. The other 80 were carried to the site by people. This isn't accidental burning — it's a staged process: collect, prepare, use, discard.

A Habit Written Across a Continent

Robson's literature review found fungi at 18 Mesolithic sites across northern Europe — Denmark, Germany, the Netherlands, Russia. At Neustadt, specimens had scrape marks consistent with tinder preparation. At Rødbyhavn, one bracket had been decorated with cross-hatching. At Tybrind Vig, two of fourteen specimens were modified. This is a shared technology, transmitted across generations and geography. The open questions are rich: how was this knowledge passed on? Through trade networks, direct contact, or something else entirely? And what other perishable technologies — wrapped in bark, made of wood and fibre and fungus — simply haven't survived to tell us what else these people knew?

• Fungi as technology, not forage — The Star Carr assemblage shows deliberate species selection, preparation, and use, confirming that bracket fungi were a managed resource, not an opportunistic find.
• Perishables rewrite prehistory — Waterlogged and peat sites like Star Carr preserve organic materials that simply don't survive elsewhere, meaning our picture of Stone Age life is almost certainly incomplete wherever such conditions are absent.
• Knowledge travels — The near-identical use of tinder fungi across 18 Mesolithic sites from Yorkshire to Russia suggests that practical knowledge moved across Mesolithic Europe far more systematically than the stone tool record alone reveals.

"Given the numerous uses of fungi documented in this chapter, it is likely that those recovered from Star Carr had probably been intentionally gathered by the site's inhabitants." — Robson, H.K., Star Carr Volume 2: Studies in Technology, Subsistence and Environment, White Rose University Press, 2018.
