Chloroscypha flavida

Species Fungorum (2018) transfers Gelatinodiscus flavidus to Chloroscypha flavida.

This species is one of the snowbank fungi of the Pacific Northwest, and is known only from this region to date. It occupies a specialized niche in that it fruits on the soaked, decaying foliage of Chamaecyparis nootkatensis at or under the edge of retreating snowbanks. Its future is intimately tied to the future of the host species, but at present it is not in great danger.

It ranges from British Columbia (Eckblad 1968) south to the Ashland Resource area; and is also present in the mountains of the Olympic Peninsula (ISMS, Fogel n.d.) and the Aldrich Mountains (Frenkel 1974, reference missing). It is to be expected throughout the range of its host.

This small yellow cup-fungus fruits on dead foliage of Chamaecyparis nootkatensis under, or at the edge of, snowbanks and is known only from British Columbia (Eckblad 1968), Washington (Kanouse and Smith 1940, Fogel n.d.), and Oregon (OSC n.d., Carpenter 1976). Few people have sought the species out so it is not surprising that the number of occurrences is small.

The threats to this species are the threats to its host. I'm not sure, but rather think that in most areas the host is not a highly valued timber species so logging may not be a major threat. Development of winter recreation sites, etc. in the range of the host could limit its populations.
