Dry deciduous, mixed broadleaved and moist coniferous forests of the Sikhote-Alin State Nature Biosphere Reserve (Russian Far East) were surveyed for myxomycetes. A total of 3230 records (2717 from field collections and 513 from 321 moist chamber cultures of decaying plant material) resulted in 158 morphospecies and 3 varieties representing 36 genera. Ninety-five species from 15 genera were recorded only in the field and 30 species from 15 genera were exclusively obtained from moist chamber cultures. Eighteen taxa were found for the first time in Russia, and all the recorded species are new for the Sikhote-Alin reserve. The Chao1 estimator indicated that our sampling effort was sufficient to recover all of the more common species in the studied area. Among three studied forest types, dry deciduous, mixed broadleaved, and moist coniferous forests, completeness of the survey is lowest for the latter. As indicated by the Shannon index, species richness and diversity increase progressively from dry deciduous (75 species, H' = 2.5) over moist coniferous (65 species, H' = 3.7) to mixed broadleaved forest (130 species, H' = 4.1). In contrast, the myxomycete assemblage of dry deciduous forests is the most distinctive among the three forest types. Among substrate types, species diversity and richness increase from litter over bark to wood, and parallel to this the slope of the individual-based species accumulation curves increases. The overall high species richness and diversity of myxomycete biota in the reserve may be explained by the monsoon climate, which is similar to that of the Manchurian and Japanese mixed broadleaved forests.
