Caloscypha is a fungal genus in the family Caloscyphaceae (order Pezizales). A monotypic genus, it contains the single species Caloscypha fulgens, commonly known as the snowbank orange peel fungus, spring orange peel fungus, the golden cup, or the dazzling cup. It is a cup fungus, typically up to 4 centimetres (1+58 in) in diameter, with a bright to pale orange interior and orange; specimens that are old or bruised often have an olive-green discoloration, especially around the edges.

In North America, C. fulgens is usually found on the ground in forest litter near conifers. Fruiting occurs in early spring following snow melt. The asexual (imperfect), or conidial stage of C. fulgens is the plant pathogenic species Geniculodendron pyriforme, known to infect dormant seeds of the Sitka spruce.
