Caloscypha fulgens
blue-staining cup, dazzling cup, snowbank orange peel fungus

Distribution: Although most common in the western mountains, it occurs across North America, as well as in Europe and temperate Asia.

Conservation Status: Not of concern

Identification Notes:

Caloscypha fulgens is another medium-sized orange cup that could be confused with Aleuria aurantia. Like Pseudaleuria quinaultiana, however, it is a spring-fruiter, one of the common members of the western montane snowbank mycota that fruit in areas recently uncovered by melting snow. In addition to its habitat and fruiting season, it can be distinguished from the other orange cups by the blue to green staining that occurs as the fruitbodies age. C. fulgens is a parasite of conifer seeds.
