<p>Damping-off of leaf lettuce (Lactuca sativa var. crispa) occurred in Ibaraki Prefecture in September, 2013.

We propose that P. aphanidermatum should be added to the pathogens of damping-off of lettuce. The degree of virulence, rot and wilt of leaves, and growth inhibition of plant, was more remarkable at relatively high temperature conditions.</p>
