There are nine species of Earthtongue in the UK, a fungus that is often mistaken for Dead Man’s Fingers (Xylaria polymorpha). Like blackcurrant lollipops, their dark fruiting bodies stick up from the soil. Varying from black to an olive green, dependent on the species, they are found in short grassland and Sphagnum peats. To distinguish between the different species, which are spread across the genera Geoglossum, Microglossum and Trichoglossum, microscopic investigation is generally required.
