Abstract:	Isozyme patterns for 15 enzymes from mycelial extract were compared with 10 isolates each of Phialophora gregata from adzuki bean (Phaseolus angularis) and soybean (Glycine max) and one isolate each of Acremonium sp. from adzuki bean and Cephalosporium gramineum from wheat. These three species showed considerable different patterns in all the enzymes tested with the coefficient of similarity of 0.05. The adzuki bean and soybean isolates of P. gregata exhibited the same patterns in 11 enzymes. Four other enzymes, i.e lactate dehydrogenase, peroxidase, .alpha.-esterase and acid phosphatase, distinguished these two groups of isolates. The coefficient of similarity within each group of the adzuki and soybean isolates and between the groups were 0.83, 0.97, and 0.64, respectively. These results support the recognition of the two groups as separate formae speciales of P. gregata.
