葡萄穗霉科3个中国新记录种
Three Newly Recorded Species of Stachybotryaceae from China
摘要
Abstract
Five stachybotryaceous strains isolated from soil samples collected in Beijing City,Hubei Province,and the Xinjiang Uygur Autonomous Region were investigated through morphological assessment and multilocus phylogenetic analyses.Alfaria dactyli,Paramyrothecium viridisporum,and Xenomyrothecium tongaense were identified and documented as novel records for China.A.dactyli is characterized by the production of large,lanceolate,pale green conidia.P.viridisporum is distinguished by its obovoid to ellipsoidal conidia,whereas X.tongaense exhibits oblong-ellipsoidal conidia and notably lacks setae within the sporodochia.Detailed descriptions and illustrations of the colony morphology and microscopic features of each species are provided.Their taxonomic placements were corroborated through sequence analyses of combined internal transcribed spacer(ITS)regions alongside either the RNA polymerase Ⅱ second largest subunit(rpb2)or β-tubulin gene sequences.These findings contribute to the understanding and expansion of Stachybotryaceae species diversity within China.关键词
