Myxomycetes are fungus-like amoeboid protists that primarily inhabit plant detritus and humus in terrestrial ecosystems (Stephenson, 2011), preferring habitats such as dead wood, litter, soil, and living tree bark, based on differences in the substrates and microenvironments (Novozhilov et al., 2022). Their fruited sporangia mostly disperse spores by wind (Kamono et al., 2009) and reproduce on various substrates. Some species known as bark-dwelling myxomycetes (corticolous myxomycetes) extend their habitat to the bark surface of living trees, where they complete their life cycle (Keller & Brooks, 1973). Although these species mostly possess minute fruiting bodies with an ephemeral existence and are rarely observed in the field, they can be reliably detected using the moist chamber culture technique (Michell, 1977).Trees of the species Metasequoia glyptostroboides Hu et W. C. Cheng were found as fossils from the Cretaceous by Dr. Shigeru Miki (Tsukagoshi et al., 2011) and later discovered as an extant plant in China (Hu, 1946;Hu & Cheng, 1948); the species is therefore regarded as a "living fossil." Even though the species became extinct in the Japanese archipelago during the 4 th Cenozoic period (Momohara, 2011), present specimens in Japan derive from 100 seedlings that were a present from Dr. R. W. Chaney from the USA (Tsukagoshi et al., 2011). The species was then propagated to schools, companies, and the public through cuttings planted throughout the country and was used as a garden and roadside tree in green areas in conurbations, local cities, rural areas, and in afforestation to examine its usefulness for timber production (Tsukagoshi, 2016). The bark surface provides a habitat for many myxomycetes that grow on bark surface (Takahashi, 2014).Urbanization is presumed to cause various environmental changes (Grimm et al., 2008;Güneralp & Seto, 2013) along with habitat loss and fragmentation, resulting in impacts on biodiversity and ecological processes (Liu et al., 2016). Urbanization has increased globally and is rapidly spreading. The urban population in three conurbations in Japan is expected to reach 56.7% of the country's total population by 2050 (Ministry of Internal Affairs and Communications, www.soumu.go.jp). Understanding the effects of urbanization on biodiversity is thus of vital importance. Although the effects of urbanization on species richness have been studied and discussed for large visible plants, animals, birds, and arthropods (Faeth et al., 2011;McKinney, 2008), the importance of saproxylic microbes and the effects of urbanization on microbial diversity remain to be studied in detail (Korhonen et al., 2022).
