Gassicurtia

Gassicurtia is a genus of lichenized fungi in the family Caliciaceae.

Taxonomy
The genus was circumscribed by French botanist Antoine Laurent Apollinaire Fée in Essai Crypt. Exot. (Paris) 1: XLVI, 100 in 1825.

The genus name of Gassicurtia is in honour of Louis Claude Cadet de Gassicourt (1731–1799) who was a French chemist who synthesised the first organometalic compound.

It was later resurrected by Bernhard Marbach in his 2000 monograph on Buellia sensu lato. The genus contains species that are part of the tropical Buellia group with 2-celled ascospores, and which lack algae in the margin.
