Аннотация:The tropical forests of Vietnam are distinguished by a high species diversity of myxomycetes. The paper presents the results of analysis of the myxomycete diversity on the basis of field collecting of the fruit bodies, as well as moist chamber cultures prepared with samples taken from the bark surface of living trees and vines, ground and aerial litter and coarse woody debris. Detailed comparative analysis using methods of multidimensional statistics allowed us to reveal some trends in their distribution on high-altitude gradient, and also in various biotopes and substrates. Species richness and abundance are lower in middle-mountainous forests in comparison with lowland forests. In the mountain tropical forests these indicators decrease with increasing altitude and have minimal values in cloud forests. The abundance and species richness of myxomycetes decrease with an increase in the moisture content of substrates. The species composition of the substrate assemblages of mountain forests differs from that in the lowland forests. Some species which are common in temperate and boreal zone are registered also in the mountainous tropical forests of Vietnam.
