Twenty-six species of microfungi are treated, the majority of which are associated with leaf spots of Corymbia, Eucalyptus and Syzygium spp. (Myrtaceae). The treated species include three new genera, Bagadiella, Foliocryphia and Pseudoramichloridium, 20 new species and one new combination. Novelties on Eucalyptus include: Antennariella placitae, Bagadiellalunata, Cladoriella rubrigena, C. paleospora, Cyphellophora eucalypti, Elsinoë eucalypticola, Foliocryphia eucalypti, Leptoxyphium madagascariense, Neofabraea eucalypti, Polyscytalum algarvense, Quambalaria simpsonii, Selenophoma australiensis, Sphaceloma tectificae, Strelitziana australiensis and Zeloasperisporium eucalyptorum.Stylaspergillus synanamorphs are reported for two species of Parasympodiella, P. eucalypti sp. nov. and P. elongata, while Blastacervulus eucalypti, Minimedusa obcoronata and Sydowia eucalypti are described from culture. Furthermore, Penidiella corymbia and Pseudoramichloridium henryi are newly described on Corymbia, Pseudocercospora palleobrunnea on Syzygium and Rachicladosporium americanum on leaf litter. To facilitate species identification, as well as determine phylogenetic relationships, DNA sequence data were generated from the internal transcribed spacers (ITS1, 5.8S nrDNA, ITS2) and the 28S nrDNA (LSU) regions of all taxa studied.

本文共描述了 26 种小型真菌，其中大多数与桃金娘科的南洋杉属、桉树属和蒲桃属植物的叶斑有关。处理过的物种包括三个新属，即 Bagadiella、Foliocryphia 和 Pseudoramichloridium，20 个新种和一个新组合。桉树属的新种包括：Antennariella placitae、Bagadiellalunata、Cladoriella rubrigena、C. paleospora、Cyphellophora eucalypti、Elsinoë eucalypticola、Foliocryphia eucalypti、Leptoxyphium madagascariense、Neofabraea eucalypti、Polyscytalum algarvense、Quambalaria simpsonii、Selenophoma australiensis、Sphaceloma tectificae、Strelitziana australiensis 和 Zeloasperisporium eucalyptorum。本文还报道了两种拟茎点霉属 Parasympodiella 的 Stylaspergillus 同孢现象，即 P. eucalypti sp. nov. 和 P. elongata，同时还从培养物中描述了 Blastacervulus eucalypti、Minimedusa obcoronata 和 Sydowia eucalypti。此外，Penidiella corymbia 和 Pseudoramichloridium henryi 是在南洋杉属上新描述的，Palleobrunnea pseudocercospora 是在蒲桃属上新描述的，而 Rachicladosporium americanum 则是在叶凋落物上新描述的。为了便于物种鉴定和确定系统发育关系，本文从研究的所有分类群的内部转录间隔区（ITS1、5.8S nrDNA、ITS2）和 28S nrDNA（LSU）区域生成了 DNA 序列数据。
