Theobroma cacao as culinary, purposes. Some mixtures included maize, chili, vanilla ("Vanilla planifolia"), and honey. Archaeological evidence for use of cacao, while relatively sparse, has come from the recovery of whole cacao beans at Uaxactun, Guatemala and from the preservation of wood fragments of the cacao tree at Belize sites including Cuello and Pulltrouser Swamp. In addition, analysis of residues from ceramic vessels has found traces of theobromine and caffeine in early formative vessels from Puerto Escondido, Honduras (1100–900 BC) and in middle formative vessels from Colha, Belize (600–400 BC) using similar techniques to those used to extract chocolate residues from four
Moniliophthora perniciosa Moniliophthora perniciosa Moniliophthora perniciosa (previously "Crinipellis perniciosa") is a fungus that causes "witches' broom disease" (WBD) of the cocoa tree ("Theobroma cacao" L.). "T. cacao" a tropical tree with seeds that are processed into cocoa (=cacao) products. This pathogen is currently limited to South America, Panama and the Caribbean, and is perhaps one of the best-known cocoa diseases, thought to have co-evolved with cocoa in its centre of origin (first recorded in the Brazilian Amazon in 1785). This fungus is hemibiotroph, with two characteristic phases: biotrophic (expanding and infecting, on living tissue) and saprotrophic (producing basidiospores, on necrotic tissue). The
