Mating reactions (production of normal or abnormal ascospores/with high, medium, low or no germination) in two replicated pairing experiments between MAT1, female tester strains of Ceratocystis spp. in the Latin American clade and MAT2, male testers of Ceratocystis lukuohia, C. platani and Ceratocystis sp. from Syngonium.

1 Microscopic examination of abnormal ascospore masses showed more than 10 % of the ascospores misshapen or empty and typically with ascus or ascospore debri. Streaked ascospore mass on malt yeast extract agar: high germination = colonies too numerous to count on three plates; medium germination = 40 or more colonies on three plates; and low germination = fewer than 40 colonies on the three plates. Pairings or ascospore germinations not tested are indicated by NT.
