Members of Venturiales (Dothideomycetes) are widely distributed, and comprise saprobes, as well as plant, human and animal pathogens. In spite of their economic importance, the general lack of cultures and DNA data has resulted in taxa being poorly resolved. In the present study five loci, ITS, LSU rDNA, tef1, tub2 and rpb2 are used for analysing 115 venturialean taxa representing 30 genera in three families in the current classification of Venturiales. Based on the multigene phylogenetic analysis, morphological and ecological characteristics, one new family, Cylindrosympodiaceae, and eight new genera are described, namely Bellamyces, Fagicola, Fraxinicola, Fuscohilum, Neofusicladium, Parafusicladium, Pinaceicola and Sterila. In addition, 12 species are described as new to science, and 41 new combinations are proposed. The taxonomic status of 153 species have been re-evaluated with 20 species excluded from Venturiales. Based on this revision of Venturiales, morphological characteristics such as conidial arrangement (solitary or in chains) or conidiogenesis (blastic-solitary, sympodial or annellidic), proved to be significant at generic level. Venturia as currently defined represents a generic complex. Furthermore, plant pathogens appear more terminal in phylogenetic analyses within Venturiaceae and Sympoventuriaceae, suggesting that the ancestral state of Venturiales is most likely saprobic.

Venturiales ( Dothideomycetes ) 的成员分布广泛,包括腐生以及植物、人类和动物病原体。尽管它们具有经济重要性,但普遍缺乏文化和 DNA 数据导致分类群难以解决。在本研究中5个基因座,ITS,LSU rDNA的,TEF1TUB2RPB2用于分析115 venturialean类群表示在当前分级三个家族30属Venturiales。基于多基因系统发育分析,形态和生态特征,一个新的家庭,Cylindrosympodiaceae,和八个新属描述,即Bellamyces, Fagicola, Fraxicola , Fuscohilum, Neofusicladium , Parafusicladium , PinaceicolaSterila。此外,12个物种被描述为科学新物种,并提出了41个新组合。重新评估了 153 个物种的分类地位,其中 20 个物种被排除在文丘里目之外。根据文丘里目的这一修订,形态特征如分生孢子排列(单生或成链)或分生孢子发生(胚芽-单生、合生或环节生)在属水平上被证明是重要的。文丘里当前定义的代表通用复合体。此外,植物病原体内出现在系统发育分析多个末端VenturiaceaeSympoventuriaceae,表明祖先状态Venturiales是最有可能saprobic。
