The myxomycetes are eulcaryotic unicellular organism. They live in forest floor and feed on micro-organisms such as bacteria, molds, algae and protozoa that inhabit soil, fallen leaves or rotten wood. They make spores and spores are scattered from a fruit body by the wind. When a spore falls in a suitable place for germination, its spore buds and grows. This study aims to develop how to use the myxomycetes as a bio-indicator showed the quality of the urban green environment. The results showed that 222 kinds of the myxomycetes occurred in 35 urban green in Tokyo. For this reason, it reveals that a number of the myxomycetes live in narrow or isolated urban green. Twelve kinds of the myxomycetes were found in investigation at Showa Memorial Park. The myxomycetes lives in the secondary forest covered with fallen leaves and rotten wood, but we couldnt find them in the forest which ground is hard or grassed down. According to the results derived in our study and other reference, it needs study to put the myxomycetes as bio-indicator to practical use, example observations of life and case of environmental education or museum exhibit about the myxomycetes. However, we appreciate the myxomycetes as new bio-indicator of urban green environment because of the advantage that if there is a suitable place for living, the myxomycetes can live in urban green because spores of the myxomycetes are scattered by the wind.
