Isolates of Phytophthora from fruit crops, previously identified as P. cryptogea on the basis of standard morphological criteria, were compared using electrophoretic patterns of total soluble mycelial proteins and isozyme analysis. According to these criteria, all 33 isolates recovered from kiwifruit in Chile were similar or identical to isolates from California recovered from kiwifruit, apple, and cherry. In contrast, the Chilean and California isolates appeared no more related to New York isolates of P. cryptogea than they were to isolates of P. cactorum, P. cinnamomi, and P. megasperma that were similarly examined. Isolates identified as P. cryptogea from deciduous fruit crops in New York appear to belong to a different taxon than isolates of P. cryptogea from fruit crops in Chile and California
