Notes: Abstract: Variation in esterase isozymes of three host races of this species, associated with Cryptomeria japonica, Torreya nucifera and Taxus cuspidata analyzed by polyacrylamidegel electrophoresis; comparisons made between collection years and among localities within each host race; the results suggest the presence of differentiated host specificity in A. cryptomeriae.
