Speerschneidera

Speerschneidera is a single-species genus of lichen-forming fungi in the family Leprocaulaceae. The genus was circumscribed by Italian botanist Vittore Benedetto Antonio Trevisan de Saint-Léon in 1861, with Speerschneidera euploca as the type species. This lichen was originally described by Edward Tuckerman in 1858 as Physcia euploca. It is a crustose lichen found in the southern United States and Mexico.

The genus name Speerschneidera honours German doctor, teacher and naturalist Julius Ferdinand Speerschneider (1825–1903). He worked as a curator of Frederick Charles, Prince of Schwarzburg-Rudolstadt's natural history collection which later became the Natural History Museum in Rudolstadt.
