Tholurna

About

Tholurna is a fungal genus in the family Caliciaceae. The genus is monotypic, containing the single species Tholurna dissimilis. Long thought to be confined to Scandinavia, it has since been recorded in western North America, where a 1983 survey documented 47 localities from coastal British Columbia to Oregon and as far north-east as the Yukon and Northwest Territories.
