Archaeorhizomyces is a class of filamentous fungi in Ascomycota, and is abundant in soil. However, seldom has it been deeply researched. Archaeorhizomyces finlayi and Archaeorhizomyces borealis are two different species of Archaeorhizomycetes. Some filamentous fungi can exhibit dimorphic switch between multicellular hyphae and unicellular yeasts; besides, many fungi also produce conidia or other asexual spores under certain situation. These conditions convey the information about growth preferences and life cycles dynamics. In this report, the differences between A. finlayi and A. borealis in their growth as yeasts and formation of conidia in response to different pH and nitrogen sources are observed and discussed, for a deeper understanding of their life cycles. Results turn out that they have different preferences to certain media for producing conidia and yeasts, which means that they may have different life strategies. Besides, chlamydospore were observed in A. borealis culture in tested conditions, chlamydospore reflecting differences between the two species.
