Discina ancilis, also known as the Shield-like Discina or Schildförmige Discina in German, is a species of fungi belonging to the Discinaceae family. This ascomycete fungus is characterized by its distinct shield-like or saddle-shaped fruiting body, which can reach up to 8 cm in diameter. The cap of D. ancilis is typically reddish-brown or dark brown in color and has a smooth, waxy surface. The margins of the cap are often wavy or irregular, contributing to the shield-like appearance. The underside of the cap in D. ancilis does not have gills or pores; instead, it is smooth or slightly wrinkled, with a lighter coloration than the upper surface. The stipe, or stem, is short, thick, and often off-center, with a similar color to the cap. Discina ancilis is commonly found in the Northern Hemisphere, particularly in North America and Europe. It typically grows on the ground in mixed or coniferous forests, often near decaying wood or in mossy areas. The fruiting period for D. ancilis usually occurs in spring, sometimes extending into early summer, depending on environmental conditions and geographical location. The spores of D. ancilis are ellipsoid and hyaline, measuring approximately 20-25 x 7-10 micrometers. The asci, or spore-producing structures, are cylindrical or club-shaped, containing eight spores each. Microscopically, D. ancilis features paraphyses, which are elongated, sterile cells interspersed among the asci. These paraphyses are septate and may contain pigments. Despite its intriguing appearance, D. ancilis is not considered an edible mushroom due to its tough, leathery texture and lack of appealing flavor. It is not known to be toxic, but it is not recommended for consumption. Discina ancilis plays an important ecological role as a decomposer, helping to break down organic material in the forest ecosystem. It forms mycorrhizal associations with trees, which is beneficial for both the fungus and the host plant. The Shield-like Discina is not a well-studied species, and further research is needed to better understand its biology, distribution, and ecological significance.
