Discina is a genus of fungi that is commonly known as "earth tongues" due to their elongated, tongue-like appearance. Synonyms for Discina include Geoglossum, Microglossum, and Trichoglossum, all of which also refer to species with elongated fruiting bodies. These fungi are typically found in moist soil, leaf litter, and decaying wood, and play an important role in nutrient cycling and decomposition processes in forest ecosystems. Although some species of Discina are edible, others can be toxic or of unknown edibility, so it is important to exercise caution and proper identification when foraging for these fungi.
