There is a burgeoning awareness of the importance of fungi, whose role is to be discussed at the COP16 conference in Colombia (Robyn Beck) (Robyn Beck/AFP/AFP)
You can't walk very far through a forest in this part of the United States without stumbling upon a mushroom, an eruption from a vast fungal kingdom that all life depends on, but about which we know very little.
Some are tall and thin with a helmet top, others are great flourishes of brain-like folds; some seem like they should be sheltering fairies in a storybook.
Many look like they could be delicious in the hands of a skilled chef; others... decidedly not.
But the dozens of species that enthusiasts and experts collected on a recent morning represent just a tiny fraction of life that is neither flora nor fauna.
"Mushrooms are not plants," said Amy Honan, who teaches mycology and fungal ecology at Oregon University.
"Fungi are more closely related to animals than they are to plants."
Plants make their own food through photosynthesis, but mushrooms have to eat something else.
"They spit out different enzymes, so they break down their food outside of their body, and they slurp it up like a smoothie," Honan said.
- 'Essential' -
Of the at least 2.5 million species of fungus thought to exist on Earth, scientists have described around 150,000 -- six percent -- Honan told AFP during a field trip near Port Angeles in Washington state.
Compared with what we know about plants and animals, that's practically nothing.
"We know about 98 percent of the vertebrates that are on the planet," she said. "We know about 85 percent of plants that exist on the planet. We know about 20 percent of invertebrates."
This paucity of fungal knowledge is troubling because of the vital -- and largely unseen -- role that they play.
Fungi evolved before plants and created the conditions to allow vegetation to move from the sea to the land.
"Fungi are essential for all terrestrial ecosystems. They confer all kinds of benefits to plants, from salt tolerance, heavy metal tolerance, disease resistance," Honan said.
"Basically, without fungi... plants would not exist. We need plants for oxygen, so the world would not exist in its current state."
It would also be chock-full of dead things.
"Fungi break down all dead organic material, so they recycle all that carbon and other nutrients," facilitating the life cycle of plants and animals.
- COP16 focus -
There is a burgeoning awareness of the importance of fungi, whose role is set to come up for discussion at the UN Convention on Biological Diversity COP16 meeting in Colombia, which kicks off on Monday.
The Guardian newspaper reported last week that a joint proposal by Chile and the United Kingdom could see fungi recognised as "an independent kingdom of life in legislation, policies and agreements, in order to advance their conservation and to adopt concrete measures that allow for maintaining their benefits to ecosystems and people."
Greater protections would be good news, said mycologist Graham Steinruck, who, along with Honan, is leading a study into fungal biodiversity at a site that was underwater until the removal of a dam a few years ago.
As part of the Olympic Peninsula Fungi Festival, he and Honan have taken participants out into the field to show them how to find species of mushroom, and how to record what they are seeing.
"I think the more fungi that we go out and discover and document not only tells us about our biodiversity, but also can tell us about ways we can steward the land better," Steinruck said.
Knowing more about these mysterious organisms could also bring benefits to lots of areas of human life.
Mushrooms can help us "heal ourselves, and maybe even potentially (help) other things like industries," he said.
For participants on the mushroom hunt, the opportunity to find new fungal life was eye-opening.
Naomi Ruelle had traveled from New York with her mushroom-enthusiast partner, and was taking part in her first organized hunt.
"I've learned so much," she beamed, showing off a collection that included a huge, fleshy shelf-like specimen, yellow parasol-style mushrooms and spindly stalked fungi that had found root in a dead pine cone.
"It was so interesting to see the different species. They're obviously going to take them to the lab and I'm kind of curious to understand a bit more about them."
UK dog owners issued mushroom warning as autumn arrives
KEEP THEM OUT OF THE SOUP POT TOO

Dog owners are being warned about the dangers of fungi and mushrooms as the UK enters peak mushroom season.
The period between September and November is when mushrooms are most common, and while they may be a pretty sight during a winter walk, some can be fatal to dogs.
Kennel Store, a pet care expert, explained the risks associated with dogs consuming mushrooms.
Wild mushrooms are prevalent in autumn and can often be found in parks, woodlands, and gardens.
Certain types of these mushrooms can be toxic to dogs and can rapidly grow in mild, wet conditions, making them easy for pets to encounter.
Some of the common poisonous mushrooms in the UK include Fly Agaric, known for its distinctive fairy-tale appearance with a red cap and white spots; Death Cap; Deadly Webcap; Funeral Bell; Destroying Angel; Fool’s Funnel; Panther Cap and Angel’s Wings.
The symptoms of mushroom poisoning in dogs can vary depending on the type of mushroom ingested.
However, pet owners should be vigilant for signs such as vomiting, stomach pain, diarrhoea, lethargy, excessive drooling, loss of balance, yellowing of the eyes, skin and gums, seizures, loss of motor control, collapse, organ failure, or coma.
If a dog owner suspects that their pet has eaten a poisonous mushroom, it is critical to seek veterinary attention immediately.
Taking a photograph or a sample of the ingested mushroom can help the vet determine the appropriate treatment.
Pet owners should also be aware that their dog may not necessarily be seen eating a mushroom.
If a dog exhibits unusual behaviour following a walk, such as neurological signs, agitation, or unusual vocalisation, it is advisable to visit the vet.
