A fungus species previously unknown to exist in Britain has been found growing in an ancient woodland area of Sussex.
Nature lover Liz Frost identified the Blue-Based Earthtongue specimen at the Kingley Vale National Nature Reserve close to Chichester.
According to Ms Frost, she was thrilled to come across this distinctive miniature fungus with its tongue-like appearance while walking through the reserve. She had no idea at the time that she had just documented the very first British occurrence of the Blue-Based Earthtongue.
The small, tongue-shaped fungus, scientifically termed Microglossum cyanobasis, was discovered growing within the reserve’s venerable yew woodland section.
This marks only the second documented sighting of this particular species anywhere on the continent.
Previously, the fungus had only been recorded once in Europe, specifically in Spain nearly two decades ago.
The organism can reach heights of up to 55 millimetres and possesses a subtle blue-green colouring at its base, a characteristic feature that distinguishes it from comparable fungal species.
Its diminutive and delicate nature contributed to its common name, while the term cyanobasis translates directly to blue base in reference to this distinctive colouring.
Genetic analysis, conducted with assistance from the British Mycological Society, verified the identification, indicating that English habitats maintain excellent ecological conditions.
Rachel Guy, who manages the reserve on behalf of Natural England, commented that this fungal discovery demonstrates the presence of excellent-quality environments and underscores the importance of England’s network of 224 National Nature Reserves. She noted that the fungus indicates the existence of undisturbed, low-nutrient grassland areas and ancient woodland ground conditions. She added that such habitats are growing increasingly unusual due to agricultural improvement, drainage schemes, ploughing practices and modifications in land management.
Kingley Vale Nature Reserve contains one of the continent’s finest yew tree collections, with certain specimens believed to exceed 500 years in age.
The 150-acre site welcomes visitors, though dogs must remain on leads to safeguard the environment and grazing animals.
