In this survey, we examined distribution and habitat of Lecanorchis suginoana in Nagoya University campus. Compared with results of a distributional survey in 2005, a number of individuals were reduced, and the distribution has changed, including a local migration to a new habitat. It was suggested that Lecanorchis suginoana in the study area have changed the distribution depending on the change of the state of the forest. According to the observations on the roots, the flowered individuals were associated with many roots, whereas non-flowered individuals (individuals that did not flower this year) tend to associate with a few roots. It was suggested that the opening of a flower is greatly influenced by the number of the roots.
