With ITS RFLP all strains of H. werneckii were found to be identical, except for a band length difference of about 20 bp in three strains; this length difference was found with DdeI and HaeIII digestion, due to extra restriction site in ITS1 (Positions 3 and 32) generating minute fragments. This did not correlate with the extra restriction site found with SSU*HinfI B patterns in nine strains (Table 2).
