Chromosera citrinopallida is a species of waxcap mushroom in the family Hygrophoraceae, found in old-growth grasslands and woodland pastures in Europe. Waxcap fungi of the family Hygrophoraceae are characteristic species of unimproved grasslands that have not been subject to fertilization, plowing, or herbicide application for many decades. These grassland waxcap communities are considered indicators of high ecological value and ancient, undisturbed grassland continuity. The fruiting bodies of Chromosera citrinopallida are small and typically display pale yellowish or citrine coloration, as suggested by the specific epithet. Waxcap grasslands of northern and western Europe, including those in the United Kingdom, Scandinavia, and the Baltic states, support exceptional diversity of fungi including waxcaps, earthtongues, and clavarioid species, and are recognized as priority habitats for conservation. Chromosera citrinopallida, like many specialist grassland fungi, is sensitive to changes in soil chemistry caused by fertilizer application, which alters fungal community composition and eliminates specialist species. The species is likely to have declined alongside the widespread loss of traditional meadow and pasture management across Europe during the twentieth century.
