| مستخلص: | P. umbellatus sclerotium is a traditional Chinese medicine that is widely utilized in China, Korea, Japan, and other countries due to its diverse medicinal activities, such as diuretic, antitumor, anticancer, and immune system enhancement effects. Conidia, which are common asexual spores in various fungi, are not universally present in Polyporus species. In this study, the asexual life cycle of P. umbellatus was elucidated. Conidia, i.e. arthorconidia, were produced by both dikaryotic and monokaryotic strains. In the dikaryotic strain, binucleate, uninucleate, and nuclei-free conidia were identified with proportions of 67.9 %, 12.4 %, and 19.7 %, respectively. Conversely, the monokaryotic strain did not produce binucleate conidia. This discrepancy suggests that binucleate spores are heterokaryons, while uninucleate spores are homokaryons. Clamp connections were observed in dikaryotic hyphae, but were absent in monokaryotic hyphae. Monokaryotic strains were obtained from conidia of the dikaryotic strain. Additionally, mating types were determined through pairing tests, and successful crossbreeding occurred between monokaryotic strains derived from conidia and basidiospores from different strains. This study introduced the first crossbreeding strategy for P. umbellatus. Competing Interests: Declaration of competing interest 1.
