Guepiniopsis alpina, commonly known as the jelly cup, alpine jelly cone, or poor man's gumdrop, is a species of fungus in the family Dacrymycetaceae. The small, gelatinous Fruit bodies are orange and cone or cup shaped. Found in western North America and Iran, the fungus grows on decaying conifer wood.


The fungus was first described in 1901 by Samuel Mills Tracy and Franklin Sumner Earle under the name Guepinia alpina in 1901.[2] It was later transferred to Heterotextus in 1932,[3] and then to Guepiniopsis in 1938.[4]

It is commonly known as the "jelly cup",[5] "alpine jelly cone", or "poor man's gumdrop".[6]


The fruit bodies are cone-shaped, measuring up to 1.5 cm (0.6 in) in diameter, and hang from a narrow attachment to the substrate. They are bright yellow to orange, with a smooth and sticky surface and gelatinous texture. Dried fruit bodies deepen to reddish-orange and become hard. Its edibility is unknown, but it is too small to be considered for the table.[7] Basidiospores are produced on the inner surface of the cup. In mass, the spores are yellowish. They are sausage shaped, measure 11–18 by 4–6 µm, and have three or four septa. Like all members of the Dacrymycetes, the basidia are Y-shaped.[6]

G. alpina has been claimed to be edible, but tastes bland at best.[8] One guide classifies it as inedible.[9]

Species with which G. alpina could be confused include Bisporella citrina, Dacrymyces capitatus, and D. stillatus.[7] Guepiniopsis chrysocomus is a related species with a somewhat similar appearance. It has a yellow fruit body, larger spores, and uses rotting hardwood as a substrate.[6]

Habitat and distribution[edit]

The fruit bodies grow scattered, in groups, or clusters on decaying, bark-free conifer wood. A snowbank fungus, it is most common at higher elevations after snowmelt in the spring. It is found in North America west of the Rocky Mountains.[7] In 2010, it was recorded for the first time in Iran.[10]
