【Aim】 The study analyzed the current lists of quarantine fungi in China, Japan, Canada, and the European and Mediterranean Plant Protection Organization (EPPO) to provide a scientific basis for formulating an updated quarantine fungi list in China.【Method】 By utilizing information from the world's three official fungal nomenclatural repositories—Fungal Name, Mycobank, and Index Fungorum, a comparative study was conducted to examine the names, types, and quantities of quarantine fungi in the aforementioned list. 【Result】 The lists from the four countries or regions encompassed a total of 218 quarantine fungi species across two kingdoms, four phyla, 30 orders, 61 families, and 114 genera. In China, 130 species belonged to 82 genera, while in Japan, 61 species belonged to 43 genera. Canada included 41 species across 30 genera, and EPPO included 67 species within 41 genera. The proportions of taxa involved in the quarantine of fungi, varied among countries or regions. The phylum Ascomycota of the subkingdom Dikarya was the most common across all four lists. Oomycota and Basidiomycota had similar proportions in the lists of China and Japan, while Oomycota had a higher proportion in the Canadian list, and Basidiomycota dominated the EPPO list. There were 77 species unique to China, 34 unique to Japan, 22 unique to Canada, and 25 unique to EPPO. Five quarantined fungal species are common to the four countries or regions: Ceratocystis fagacearum, Phytophthora ramorum, Synchytrium endobioticum, Tilletia indica, and Thecaphora solani. 【Conclusion】 The taxonomic status of many quarantined fungi has changed due to the rapid development of mycological taxonomy. Comparing and analyzing the quarantine fungal lists of the four countries or regions with their current names, revealed a notable inconsistency in China's quarantine fungal list. Therefore, there is an urgent need to revise and improve the list of quarantined fungi in China.
