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. from the Asian-Australian clade and MAT2, male testers of Ceratocystis huliohia, C. uchidae, C. cercfabiensis and C. polychroma.

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.
