从苹果和南瓜属(Cucurbita Maxima(cv.)来自中国和美国的蓝哈伯德)，在它们的宿主底物上显示出煤烟斑点和蝇斑(SBFS)的标志。利用果实表面和培养物的形态、核糖体DNA 28S和内部转录间隔区的系统发育分析，以及在某些情况下的部分翻译延伸因子1-α基因序列，描述了7个以前未鉴定的物种和3个已知物种。假球藻是圆锥花科的一个新属，以椭圆假球藻和冠花假球藻两个种为代表。虽然假单胞菌在形态上与Veronaea相似，但这些真菌与Dissoconiaceae(Capnodiae)而不是Chaetothyriales(Herpotrichiellaceae)聚在一起。马利兰梳子和3个新种--葫芦科胡瓜、黄瓜和点状胡萝卜与尖顶黄杨亲缘关系较近，共同形成了一个新的亚枝。盘藻属(Dissoconium s.lat.)聚集在两个支撑良好的支系中，由不同的形态和文化特征支撑。随后，Uwebraunia，一个以前的Dissoconium的同义词，被复活为一个支系，并提出了新的组合，用于U australiens，U公社，U dekkeri和U Musae。此外，我们还报道了苹果上与SBF相关的针形木霉、Dissoconum sp.、U.Comme和U.dekkeri。
Zasmidium angulare, a novel species of Mycosphaerellaceae, and several novel taxa that reside in Dissoconiaceae, were identified from a collection of apples and Cucurbita maxima (cv. Blue Hubbard) from China and the USA that exhibited sooty blotch and flyspeck (SBFS) signs on their host substrata. Morphology on fruit surfaces and in culture, and phylogenetic analyses of the nuclear ribosomal DNAs 28S and internal transcribed spacer regions, as well as partial translation elongation factor 1-alpha gene sequences in some cases, were used to delineate seven previously unidentified species and three known species. Pseudoveronaea was established as a new genus of Dissoconiaceae, represented by two species, P. ellipsoidea and P. obclavata. Although Pseudoveronaea was morphologically similar to Veronaea, these fungi clustered with Dissoconiaceae (Capnodiales) rather than Chaetothyriales (Herpotrichiellaceae). Ramichloridium mali comb. nov., and three novel species, R. cucurbitae, R. luteum and R. punctatum were closely related with R. apiculatum, which together formed a distinct subclade in Dissoconiaceae. Species of Dissoconium s.lat. clustered in two well-supported clades supported by distinct morphological and cultural features. Subsequently Uwebraunia, a former synonym of Dissoconium, was resurrected for the one clade, with new combinations proposed for U. australiensis, U. commune, U. dekkeri and U. musae. Furthermore, we also reported that D. aciculare, Dissoconium sp., U. commune and U. dekkeri were associated with SBFS on apples.
