ABSTRACT=<p>Wood-inhabiting fungi play a significant role in wood degradation and the cycle of matter in the ecological system. In the present study, three new wood-inhabiting fungal species, <italic>Trechispora bambusicola</italic>, <italic>Trechispora fimbriata</italic>, and <italic>Trechispora fissurata</italic> spp. nov., are nested in <italic>Trechispora</italic>, which are proposed based on a combination of morphological features and molecular evidence. Sequences of internal transcribed spacer (ITS) and large subunit (nLSU) regions of the studied samples were generated, and the phylogenetic analyses were performed with maximum likelihood, maximum parsimony, and Bayesian inference methods. The phylogenetic analyses inferred from ITS showed that <italic>T. bambusicola</italic> was sister to <italic>Trechispora stevensonii</italic>, <italic>T. fimbriata</italic> grouped with <italic>Trechispora nivea</italic>, and <italic>T. fissurata</italic> grouped with <italic>Trechispora echinospora</italic>. The phylogenetic tree based on ITS + nLSU sequences demonstrated that <italic>T. bambusicola</italic> formed a single lineage and then grouped with <italic>Trechispora rigida</italic> and <italic>T. stevensonii</italic>. <italic>T. fimbriata</italic> was sister to <italic>T. nivea</italic>. <italic>T. fissurata</italic> grouped with <italic>Trechispora thelephora</italic>.</p>
