Habitat and Range

SIMILAR SPECIES
Mitrula borealis has been recorded much less often, and is reliably differentiated by its spores. It has been found in Montana close to the Idaho border, but not otherwise confirmed from the Pacific Northwest. Mitrula lunulatospora of eastern North America is distinguished by spores 11-19 x (2)2.5-3.5(4) microns that are lunate to cymbiform [boat-shaped] and inflexible. Mitrula paludosa of Europe has spores are slightly broader (11-19(24) x (2)2.5-3.5(4) microns) than spores of Mitrula elegans. Vibrissea truncorum is somewhat similar but prefers to fruit in running water and is usually submerged - the head is usually orangish to pinkish orange and rounder and more regularly shaped than with Mitrula elegans.
