Toadstool with teeth and ghostly palm among plant and fungus finds of 2024
From a toadstool with teeth to a vine smelling of marzipan and a flower that has cheated its way out of having to photosynthesise, a weird and wonderful host of new plant and fungus species have been discovered in 2024.
Other plants given scientific names for the first time include beautiful new orchids, a ghostly palm and a hairy plant that appears to have stolen a gene from an unrelated family. The species are among the 172 new plants and fungi named by scientists from the Royal Botanic Gardens, Kew and their partners.
The species come from every corner of the globe, from woods near Tunbridge Wells in Kent in England, to African sandstone cliffs in Guinea and the forests of Indonesia.
However, botanists are in a race against time to discover many plants and fungi before the continuing destruction of the natural world drives them to extinction. The loss of species does not only mean that their unique biology is gone forever, but also their potential for use as medicine, food and even as plastic recyclers. Some of the new species in 2024 already face extinction because of cement manufacturing, cinnamon farming and timber plantations.
There are 400,000 named plant species but scientists estimate there are another 100,000 yet to be identified. Every year, scientists name about 2,500 new species of plant and the same number of fungi.
“The sheer privilege of describing a species as new to science is a thrill that not many will ever get to experience,” said Dr Martin Cheek, in RBG Kew’s Africa team. “Sadly, the devastating reality is that more often than not, new species are being found on the brink of extinction and it’s a race against time to find and describe them all.”
About 40% of named plant species are threatened with extinction, as habitats are razed for farmland and other human development, and as many as 75% of the world’s undescribed plant species are thought to be threatened with oblivion.
Toadstools most often have gills or pores under the caps to disperse their spores but those from the genus Phellodon have rows of teeth-like protuberances. This year DNA analysis revealed three new species in the UK, from woodland near Tunbridge Wells and Windsor in England, and Abernethy in Scotland. These fungi are harmed by nitrate pollution from farming and are disappearing across Europe.
