Scientists Unveil 2025’s Top 10 New Plant and Fungal Species

Scientists from the Royal Botanic Gardens, Kew, along with their international collaborators, have announced the top ten new plant and fungal species identified in 2025. This selection highlights the vast diversity of the natural world yet to be documented and emphasizes Kew’s commitment to conservation in the face of a global extinction crisis. Over the past year, researchers named 125 plants and 65 fungi worldwide, showcasing the urgent need for biodiversity preservation.

Among the notable discoveries is a “zombie” fungus that targets trapdoor spiders in Brazil’s Atlantic rainforest, alongside a critically endangered orchid from Ecuador known for its striking bloodstained petals. The list also features a peculiar snowdrop species from North Macedonia and Kosovo, along with several other significant findings.

Highlights of the New Species

The “zombie” fungus, named Purpureocillium atlanticum, was collected in November 2022 and is part of a group known for parasitizing other organisms. This fungus infects trapdoor spiders, enveloping them in a cotton-white mycelium. A fruiting body emerges from the spider’s remains, enabling the fungus to release spores and propagate. Researchers utilized advanced genome sequencing technologies in the field to accelerate their understanding of this grisly life cycle. The study was led by Dr. Joao Araujo, an Honorary Research Associate at Kew.

Another captivating species is the Telipogon cruentilabrum, a new orchid from the Andean forests of Cotopaxi, Ecuador. This orchid, named for its bloodstained lip, grows epiphytically on tree daisies and mimics female flies to attract male pollinators. Unfortunately, habitat destruction from mining and agriculture has rendered this species endangered.

Among the new discoveries, the Aphelandra calciferi stands out for its vibrant flame-like flowers, inspired by the fire demon from the animated film “Howl’s Moving Castle.” This new species from Peru has potential as an ornamental plant.

The Lithops gracilidelineata subsp. mopane, a new subspecies of “living stones” from Namibia, showcases the remarkable adaptations of plants in arid environments. It features a unique leaf structure that allows light to pass through for photosynthesis.

Conservation Concerns for New Species

While the discoveries are exciting, many of the newly identified species face significant threats. For instance, the Cryptacanthus ebo from Cameroon may have already gone extinct in its natural habitat. A report from Kew indicates that up to three-quarters of the plants yet to be described are already at risk of extinction.

Dr. Martin Cheek, Senior Research Leader at Kew, emphasizes the importance of naming new species. He states, “It is difficult to protect what we do not know, understand, and have a scientific name for. Each identification helps us better understand ecosystems.”

Dr. Irina Druzhinina, a Senior Research Leader in Fungal Diversity and Systematics at Kew, notes the vast potential for discovery within fungal taxonomy. Scientists estimate that there could be over 2 million species of fungi globally, with only around 200,000 named so far.

The process of documenting new species and understanding their roles in ecosystems is critical for conservation efforts. Kew Gardens aims to incorporate at-risk species into a network of Important Plant Areas (IPAs) and conserve their seeds at national seed banks and the Millennium Seed Bank at Wakehurst.

As the urgency of biodiversity loss intensifies, the work of taxonomists and conservationists becomes increasingly vital. Without investment in these areas, we risk losing the intricate systems that support life on Earth. Each new species described not only enriches our understanding of biodiversity but also underscores the need for action in conservation efforts worldwide.
