Description
Summary:During a survey of ascomycetous fungi associated with plant litter and submerged wood in Jilin Province, China, two hyphomycetous fungi were discovered. Morphological examination and molecular phylogenetic analyses revealed that these isolates represent two species within the genus <i>Torula</i>, which are herein described as <i>Torula changchunensis</i> sp. nov. and a new host record of <i>T. mackenziei</i>. Detailed morphological characteristics are provided, and the phylogenetic relationships of the new species are also discussed. The new species differs from <i>T. chinensis</i> and <i>T. phytolaccae</i> by having smaller conidiogenous cells, smaller conidia, and fewer septa. Preliminary assessments were conducted on <i>T. changchunensis</i> and <i>T. mackenziei</i> to evaluate their antagonistic activity against two pathogenic fungi (<i>Cladobotryum mycophilum</i> and <i>Botrytis cinerea</i>) and two pathogenic bacteria (<i>Staphylococcus aureus</i> and <i>Bacillus subtilis</i>). <i>Torula changchunensis</i> sp. nov. exhibited 67.18% inhibition against <i>C. mycophilum</i> and moderate inhibition against the pathogenic bacteria, whereas <i>Torula mackenziei</i> showed moderate-to-weak inhibitory activity against both pathogenic fungi and bacteria.
