Summary
This research discovered four new species of beneficial fungi in northern China. These fungi belong to the genus Trichoderma, which is important for agriculture and industry. The findings expand our understanding of fungal diversity and could lead to new applications.
Impacts on everyday life:
• Could provide new biological control agents for protecting crops from diseases
• May yield new sources of industrial enzymes and useful compounds
• Helps understand fungi that affect mushroom cultivation
• Contributes to biodiversity knowledge needed for ecosystem conservation
• Potential applications in sustainable agriculture and green technology
Background
The genus Trichoderma is cosmopolitan, including saprotrophs and mycoparasites in diverse ecosystems. Species have been widely used in biocontrol of plant pathogens and production of enzymes and bioactive compounds. The Harzianum clade comprises many species associated with various substrates.
Objective
To describe and characterize four new species of Trichoderma (T. lentinulae, T. vermifimicola, T. xixiacum, and T. zelobreve) discovered in northern China through morphological and molecular analyses.
Results
Four new species were identified based on morphological features and molecular phylogeny: T. lentinulae from Lentinula fruiting bodies, T. vermifimicola from vermicompost, T. xixiacum from soil, and T. zelobreve from soil and mushroom substrates. Each species showed distinct morphological characteristics and formed well-supported clades in phylogenetic analyses.
Conclusion
The study expands our knowledge of Trichoderma diversity in China, particularly within the Harzianum clade. The new species demonstrate the varied ecological niches occupied by Trichoderma and represent potential candidates for biological control applications.
