Hidden among decaying leaf litter in the rainforests of northern New South Wales is one of Australia’s most remarkable fungi, a tiny blue mushroom so unusual that it was only recognised by science in 2012.
Discovered by nature photographer Stephen Axford, Coprinopsis pulchricaerulea quickly captured attention for its vivid blue colouring and became a reminder of how much of Australia’s biodiversity remains undocumented.
It is proof that even today, entirely new species are waiting to be discovered.
Why it matters
Fungi play an essential role in keeping ecosystems healthy and functioning.
🪱 They break down dead plant material and recycle nutrients back into the soil
♻️ They support forest health by contributing to nutrient cycling and dcomposition
🕸️ They help sustain the complex relationships that underpin biodiversity
👀 They remind us that many of the most important species in nature are often overlooked
Although small and rarely seen, fungi such as Coprinopsis pulchricaerulea are part of the hidden processes that keep ecosystems alive.
Fun facts
🤓 Coprinopsis pulchricaerulea is a small blue mushroom found only rarely in Australia.
🤓 Unlike many related fungi, it produces pale spores rather than the dark spores common within its genus
🤓 Its fruiting bodies enclose spores in a truffle-like structure rarely seen in related species
🤓 Its fruiting bodies are extremely short-lived and can sometimes dissolve into liquid as they age, much like the Wicked Witch of the West in The Wizard of Oz

A deeper reflection
The discovery of Coprinopsis pulchricaerulea challenges the assumption that we already know most of the species that share our planet.
Scientists estimate there may be as many as 250,000 fungal species in Australia, yet fewer than 12,000 have been formally described.
This means the overwhelming majority of Australia’s fungi remain unnamed and largely unexplored.
In a country with more than 600,000 native species, many found nowhere else on Earth, discoveries such as Coprinopsis pulchricaerulea remind us that biodiversity is not just something from the past, but something we are still uncovering today.
How we protect forests, rainforests and other natural habitats will determine whether many of these hidden species are ever known at all.
