species are wood-infecting, filamentous ascomycetes that occur in fresh wounds on a wide variety of tree species. These fungi are mainly known as saprobes although some have been associated with disease symptoms. Six fungal isolates with typical culture characteristics of spp. were collected from wounds on native forest trees in Greece and South Africa. The aim of this study was to identify these isolates, using morphological characters and multigene phylogenies of the rRNA internal transcribed spacer (ITS) region, portions of the β-tubulin (BT1) and translation elongation factor 1α (TEF-1α) genes. The mating strategies of these fungi were also determined through PCR amplification of mating type genes. The study revealed two new species; one from in Greece and one from and in South Africa. These novel taxa have been provided with the names, and , respectively. The former species was found to have a homothallic and the latter a heterothallic mating system.
这些物种是感染木材的丝状子囊菌，出现在多种树木的新鲜伤口上。这些真菌主要被认为是腐生菌，尽管有些与病害症状有关。从希腊和南非的原生森林树木伤口上收集了六种具有典型 属培养特征的真菌分离株。本研究的目的是利用rRNA内部转录间隔区（ITS）区域、β-微管蛋白（BT1）部分和翻译延伸因子1α（TEF-1α）基因的形态特征和多基因系统发育来鉴定这些分离株。还通过交配型基因的PCR扩增确定了这些真菌的交配策略。该研究揭示了两个新物种；一个来自希腊的 ，另一个来自南非的 和 。这些新分类群分别被命名为 和 。发现前一个物种具有同宗配合交配系统，后一个物种具有异宗配合交配系统。
