Cora was originally circumscribed by the Swedish "Father of Mycology", Elias Magnus Fries, in 1825. He included a single species, until then known as Thelephora pavoniaWeber & D.Mohr. Until relatively recently, Cora was thought to contain one species, or was placed into synonymy with Dictyonema. Cora was recognized as an independent genus separate from Dictyonema in 2013. Molecular phylogenetic analysis using DNA barcoding of the internal transcribed spacer region has revealed the existence of almost 200 species in the genus, and about 450 species are predicted to exist.
Habitat and distribution
Mexico and (at least formerly) Florida are the northernmost distribution points for the genus Cora, while its southernmost locale is southern Chile. It has its highest biodiversity in the northern Andes. Biogeographic data suggests that Cora originated in South America and expanded eastward. The vast majority (95%) of the known species are found in the Americas, but the genus has also been recorded from tropical Africa, tropical Asia, and South Atlantic islands. Twelve species and subspecies have been described from Mexico; the only species known to have occurred north of Mexico is the possibly extinctCora timucua, which is known to have formerly existed in Florida.
