Assessment Notes

Taxonomic notes

Described from Lake Quinault on the Olympic Peninsula of Washington (Lusk-Newman 1986).

A brightly colored cup fungus, initially rounded and flattening with age. Color of upper surface is reddish orange with a duller pinkish, and a distinctly tomentose underside when young. Margin retains fine brown hairs with hyaline tips, underside mostly glabrous in age.

This species could be confused for Aleuria in the field, although that species tends to be brighter orange with a smooth underside. Sarcoscypha tends to be distinctly stipitate, is often more scarlet in coloration, may have pubescent appressed hairs on the underside, and always grows on wood. Scutellinia are smaller, often more disc-shaped and have coarser brown hairs on the margins.


Why suggested for a Global Red List Assessment?

Low number of occurrences, restricted habitat, small population, part of the West Coast Rare Fungi Challenge - we have looked for it and it is not common.


Geographic range

Known from wet, west side forests on the Coast Range, and Cascade foothills in the Pacific Northwest, with a single unvouchered collection on the northern California coast.


Population and Trends

Currently known from 18 observations from 15 disjunct locations across the Northwest USA.

Threats


Conservation Actions

Little is known of the life history of this species or of its habitat requirements; until they are identified, conservation actions are unknown.


Research needed

A poorly known species; habitats requirements need to be identified and a better understanding of ecology is needed. Targeted surveys should be made in suitable habitat at the peak time of fruiting (April to July) to better document the species population trends.


Use and Trade

None known.
