Cognac, France
"B. compniacensis" was first investigated in 1872 when Michel Charles Durieu de Maisonneuve and Casimir Roumeguère examined a black, sooty growth found on the walls and roof tiles of buildings near distilleries in Cognac, France at the instigation of the French pharmacist, Antonin Baudoin. It has been widely recorded in Asia, Europe and the Americas.
