, commonly known as the stalked scarlet cup
or the western scarlet cup
, is a species of fungus
in the family Sarcoscyphaceae
of the Pezizales
order. Fruit bodies
have small, bright red cups up to 2 cm (0.8 in) wide atop a slender whitish stem
that is between 1 to 3 cm (0.4 to 1.2 in) long. A saprobic
species, it is found growing on hardwood
twigs, particularly those that are partially buried in moist and shaded humus
-rich soil. The fungus is distributed in the continental United States east of the Rocky Mountains
, Central America, the Caribbean, and Asia. It is distinguished from the related species S. coccinea
and S. austriaca
by differences in geographical distribution, fruiting season, and fruit body structure. Phylogenetic
analysis has shown that it is most closely related to other Sarcoscypha
species that contain large oil droplets in their spores
. The species Molliardiomyces occidentalis
is an imperfect
form of the fungus that lacks a sexually reproductive
stage in its life cycle
The fungus, originally collected from Muskingum County, Ohio, was named Peziza occidentalis by Lewis David de Schweinitz in 1832. It was assigned its current name by Pier Andrea Saccardo in 1888. Andrew Price Morgan renamed the species Geopyxis occidentalis in 1902 because of a perceived similarity with Geopyxis hesperidea, but the name change was not adopted by subsequent authors. In 1928, Fred Jay Seaver overturned Saccardo's naming and applied the name Plectania to Sarcoscypha coccinea and other red cup fungi. In later taxonomic revisions, Richard P. Korf reinstated the genus name Sarcoscypha.
The specific epithet occidentalis, derived from the Latin word for "western", may refer to the distribution of the species in the western hemisphere. It is commonly known as the stalked scarlet cup or the western scarlet cup.
