The Venturiaceae was traditionally assigned to Pleosporales although its diagnostic characters readily distinguish it from other pleosporalean families. These include a parasitic or saprobic lifestyle, occurring on leaves or stems of dicotyledons; small to medium-sized ascomata, often with setae; deliquescing pseudoparaphyses; 8-spored, broadly cylindrical to obclavate asci; 1-septate, yellowish, greenish or pale brown to brown ascospores; and hyphomycetous anamorphs. Phylogenetically, core genera of Venturiaceae form a monophyletic clade within Dothideomycetes, and represent a separate sister lineage from current orders, thus a new order—Venturiales is introduced. A new family, Sympoventuriaceae, is introduced to accommodate taxa of a well-supported subclade within Venturiales, which contains Sympoventuria, Veronaeopsis simplex and Fusicladium-like species. Based on morphology and DNA sequence analysis, eight genera are included in Venturiaceae, viz. Acantharia, Apiosporina (including Dibotryon), Caproventuria, Coleroa, Pseudoparodiella, Metacoleroa, Tyrannosorus and Venturia. Molecular phylogenetic information is lacking for seven genera previously included in Venturiales, namely Arkoola, Atopospora, Botryostroma, Lasiobotrys, Trichodothella, Trichodothis and Rhizogenee and these are discussed, but their inclusion in Venturiaceae is doubtful. Crotone, Gibbera, Lineostroma, Phaeocryptopus, Phragmogibbera, Platychora, Polyrhizon, Rosenscheldiella, Uleodothis and Xenomeris are excluded from Venturiales, and their ordinal placement needs further investigation. Zeuctomorpha is treated as a synonym of Acantharia.

Venturiales-Dothideomycetes 新目的分子、形态和生态学重新评价。

所述Venturiaceae传统上分配给Pleosporales虽然其诊断的字符很容易地从其他pleosporalean家庭区分。这些包括寄生或腐烂的生活方式,发生在双子叶植物的叶子或茎上;小到中等大小的子囊,通常有刚毛;潮解性假骨骺;8-孢子,宽圆柱形到倒圆囊;1 隔,淡黄色、绿色或淡褐色至褐色子囊孢子;和丝状无定形。在系统发育上,文丘里科的核心属在Dothideomycetes内形成了一个单系进化枝,代表了一个独立于现有目的姐妹谱系,因此引入了一个新目——文丘里目。一个新的家庭,Sympoventuriaceae的引入是为了容纳Venturiales内支持良好的亚分支的分类群,其中包含SympoventuriaVeronaeopsis simplexFusicladium样物种。根据形态学和DNA序列分析,文丘里科共包括8个属,AcanthariaApiosporina(包括Dibotryon),CaproventuriaColeroaPseudoparodiellaMetacoleroaTyrannosorus黑星菌属. 分子系统信息缺少以前包括七个属Venturiales,即ArkoolaAtoposporaBotryostromaLasiobotrysTrichodothellaTrichodothisRhizogenee这些讨论,但他们在包容Venturiaceae是值得怀疑的。克罗托内GibberaLineostromaPhaeocryptopusPhragmogibberaPlatychoraPolyrhizonRosenscheldiellaUleodothisXenomeris被排除在Venturiales之外,它们的顺序位置需要进一步调查。Zeuctomorpha被视为Acantharia的同义词。
