Lignicolous freshwater fungi represent one of the largest groups of Ascomycota. This taxonomically highly diverse group plays an important role in nutrient and carbon cycling, biological diversity and ecosystem functioning. The diversity of lignicolous freshwater fungi along a north-south latitudinal gradient is currently being studied in Asia. In this paper, we introduce two novel freshwater taxa viz. and which were collected from freshwater substrates in Eastern Thailand. Morphological comparison based on the size of ascomata, asci and ascospores, as well as multi-gene phylogenetic analyses based on LSU, SSU, ITS and TEF1-α DNA sequences, supports their placement in (Lentitheciaceae). Descriptions and illustrations of these two new species are provided.
木生淡水真菌是子囊菌门中最大的类群之一。这个分类学上高度多样化的类群在养分和碳循环、生物多样性及生态系统功能方面发挥着重要作用。目前亚洲正在研究木生淡水真菌沿南北纬度梯度的多样性。在本文中，我们介绍了两个新的淡水分类单元，即[此处原文缺失具体名称]和[此处原文缺失具体名称]，它们是从泰国东部的淡水基质中采集到的。基于子囊果、子囊和子囊孢子大小的形态学比较，以及基于LSU、SSU、ITS和TEF1-α DNA序列的多基因系统发育分析，支持将它们归入[此处原文缺失具体属名]（ Lentitheciaceae科）。文中提供了这两个新物种的描述和图示。
