Uniquely Preserved Fungi in the Vendian (Ediacaran) of Yakutia

Remains of uniquely preserved microorganisms are found in silicified columnar stromatolites in the Byuk Formation of the Vendian (Ediacaran) in the Berezovsky Trough, the southeast of the Siberian Platform (southwestern Yakutia). The biological explanation for these microorganism remains has determined their systematic position, as fungi : yeast cells in the mycelium-yeast form, which are parasitic thalli of green algae. Cells (individuals), mycelia, hyphae, buds, mycelium branches, and outgrowths (external curvature sof the cell wall) were preserved. The following patterns have been revealed: apical growth of hyphae; daughter cells that were not separated from the mother cell; parasitism of fungi on algae and osmotrophic pattern of their consumption. A new genus and species, Sakhi solomonovi gen. et sp. nov., are described.
