Acharius Medal

The Acharius Medal is awarded by the International Association for Lichenology (IAL) for lifetime achievement in lichenology. The organization resolved at its 1990 meeting that it would simultaneously honor professional achievement and commemorate Erik Acharius (recognized as the "Father of Lichenology") by presenting a medal in his name.

The first Acharius Medal was made in 1846 by the Royal Swedish Mint for the Royal Swedish Academy of Sciences, although the original purpose for that medal is not known. Because the Swedish Mint still had the dies for the original medal, the IAL arranged for new medals to be made. The first of the new medals were awarded in that same year (1992) at the association's congress in Båstad, Sweden.
