Sarcoscypha coccinea

Sarcoscypha coccinea, commonly known as the scarlet elf cup, or the scarlet cup, is a species of fungus in the family Sarcoscyphaceae of the order Pezizales. The type species of the genus Sarcoscypha, S. coccinea has been known by many names since its first appearance in the scientific literature in 1772. Phylogenetic analysis shows the species to be most closely related to other Sarcoscypha species that contain numerous small oil droplets in their spores, such as the North Atlantic island species S. macaronesica. Due to similar physical appearances and sometimes overlapping distributions, S. coccinea has often been confused with S. occidentalis, S. austriaca, and S. dudleyi. The brilliant red interior of the cups—from which both the common and scientific names are derived—contrasts with the lighter-colored exterior. Molliardiomyces eucoccinea is the name given to the imperfect form of the fungus that lacks a sexually reproductive stage in its life cycle. The saprobic fungus grows on d......read more on Wikipedia.
