Calicium glaucellum

Widely distributed in cool temperate and temperate areas of North America, Asia, Europe, Australasia, and Central and Southern America. Although, the distribution and population sizes of this species are large enough to qualify for G5, the significant decline of the species since pre-industrial times may justify reducing the rank slightly to G4G5.

Global distribution "Common, particularly in the central and northern parts of [Scandinavia... ]. Widely distributed in cool temperate and temperate areas of both the Northern (North America, Asia, Europe) and the Southern Hemisphere (Australasia, Central and Southern America)" (Tibell 1999). Within North America, widespread in temperate and boreal regions.

Number of known occurences worldwide is probably > 1000 (including many historic); Number of known occurrences in North America is probably ca. 300; Number of known occurrences in California = 5+; Number of known occurrences in Oregon = 30+; Number of known occurrences in Washington = 12+; Number of known occurrences in British Columbia = 30+. Rikkinen (2003?) reports on 42 locations from the region. Although the number of extant occurrences worldwide is unknown, the North American occurrences (collections) are recent and are mostly extant.

Worldwide, the species has gone through drastic declines since pre-industrial times. The Pacific Northwest, due to logging, has been no exception. However, the rate of loss in the Pacific Northwest has slowed. Although little is known about the reproductive and dispersal biology of this species, it is thought that the species can overcome some habitat fragmentation and, at this point, is secure from extirpation or extinction. However, given the general old-growth association of this species, it should not be ignored in conservation actions.
