Notes: Prosopidicola mexicana is the causative agent of pod disease of Prosopis glandulosa in Mexico and the USA and it has been proposed as a biocontrol agent (Lennox et al. 2004). Prosopidicola albizziae causes stem cankers on Albizzia falcataria and has been reported from leaves of Albizzia (Crous et al. 2016b).
