Sarcoscypha dudleyi, commonly known as the crimson cup or the scarlet cup, is a species of fungus in the family Sarcoscyphaceae of the order Pezizales. It has been frequently confused with Sarcoscypha coccinea, but can be distinguished from this and other related species in Sarcoscypha by differences in microscopic characteristics, such as the presence and number of oil droplets in the spores. An imperfect form of the fungus, lacking a sexually reproductive stage in its life cycle, is classified as the species Molliardiomyces dudleyi.
In addition to its main distribution in the central to eastern United States, the fungus has also been recorded once in Bulgaria.
