A comparison of populations of Armillaria hinnulea in New Zealand and Australia.

Armillaria hinnulea has been recorded from the northwest quadrant of the 6RXWK�,VODQGRI�1HZ�=HDODQG��7DVPDQLDDQG�$XVWUDOLD��,Q�1HZ�=HD ODQG�� A. hinnulea is rare, being restricted to decaying wood in South Island Nothofagus forests. A preliminary study of the relationship between the populations of A. hinnulea was performed using DNA sequence data from the internal transcribed spacer (ITS) region of the ribosomal DNA. Two major ITS clades were observed, each of which included representative sequences from Australian collections. Within one ITS clade, one
