The analysis of the micromycete complexes of oligotrophic peat deposits in the Vasyugan Marsh by direct count and culture methods showed that the micromycete carbon comprises no more than 3% of the total peat carbon and that the microscopic fungal biomass varies from 2 to 13 tons/hectare, depending on the season and the peat deposit thickness. Fungal spores were found in all layers of the peat deposits, whereas the mycelium was found only in the active peat layer. The high abundance of eukaryotic cells in the peats was due to the presence of yeastlike cells rather than fungal spores. Analyses by culture methods showed that micromycetes were present in all peat layers and that their abundance tended to decrease with depth, except for yeasts, which were uniformly distributed in a vertical direction. The micromycete complexes of the peat deposits were similar in the diversity and abundance of dominant species but differed in the composition of minor species. Peat yeasts were dominated by ascomycetes.
通过直接计数和培养方法对瓦休甘沼泽贫营养泥炭沉积物中的微真菌复合体进行分析表明，微真菌碳占泥炭总碳的比例不超过3%，且微观真菌生物量因季节和泥炭沉积物厚度而异，范围在2至13吨/公顷之间。在泥炭沉积物的所有层中都发现了真菌孢子，而菌丝体仅在活性泥炭层中被发现。泥炭中真核细胞的高丰度是由于类酵母细胞的存在而非真菌孢子。培养方法分析表明，微真菌存在于所有泥炭层中，除酵母在垂直方向上均匀分布外，其丰度往往随深度而降低。泥炭沉积物的微真菌复合体在优势物种的多样性和丰度方面相似，但在次要物种的组成上有所不同。泥炭酵母以子囊菌为主。
