Tamarix species are small trees that grow in various natural habitats and have a wide geographic distribution. Microfungal species previously found on Tamarix and recently collected in Italy and Russia were identified based on morphological characters and analyses of gene sequence data. The sexual morph of the coelomycetous genus Homortomyces was collected for the first time and is described and illustrated. A new family, Homortomycetaceae (Dothideomycetes, families incertae sedis) is introduced to accommodate Homortomyces. Two new genera Neomicrosphaeropsis (Didymellaceae) and Tamaricicola (Pleosporaceae) are introduced in this paper. Phoma tamaricicola was recollected and is placed in Neomicrosphaeropsis based on morphology and molecular data. Ten new species, Cytospora italica, C. unilocularis, Diaporthe ravennica, Eutypella tamaricis, Neomicrosphaeropsis italica, N. novorossica, N. rossica, Keissleriella tamaricicola, Paracamarosporium tamaricis and Tamaricicola muriformis are introduced, while Alternaria tenuissima, Dothiorella sarmentorum, Neofusicoccum luteum, Paraepicoccum amazonense, Pleospora herbarum and Pseudocamarosporium propinquum are reported for the first time on Tamarix spp. with descriptions and illustrations. Multi-gene analyses show that Paraepicoccum amazonense should be placed in Pleosporineae, Pleosporales, where it is closely related to Camarosporium sensu stricto. Several herbarium specimens were studied to illustrate other fungal species recorded on Tamarix species. A comprehensive account of microfungi on Tamarix is provided, which includes a list with data from the literature, as well as those identified in the present study. The taxonomic placement of most taxa discussed in this study is based on a modern taxonomic framework based on analysis of multi-gene sequence data.

Tamarix上的微真菌

柳属物种是生长在各种自然栖息地中并具有广泛地理分布的小树。根据形态特征和基因序列数据分析，鉴定了先前在Tamarix上发现并最近在意大利和俄罗斯采集的微真菌物种。首次收集了腔肠菌类Homortomyces的有性形态，并对其进行了描述和说明。引入了一个新的家庭，Homortomycetaceae（Dothideomycetes ，不合格的科），以容纳Homortomyces。两个新属Neomicrosphaeropsis（Didymellaceae）和Tamaricicola（Pleosporaceae）在本文中进行了介绍。茎点tamaricicola被重新收集和放置在Neomicrosphaeropsis基于形态学和分子数据。十大新物种，壳囊谷子，C. unilocularis，Diaporthe ravennica，Eutypella tamaricis，Neomicrosphaeropsis谷子，N. novorossica，N.苁蓉，Keissleriella tamaricicola，Paracamarosporium tamaricis和Tamaricicola muriformis介绍，而赤极细，Dothiorella sarmentorum，Neofusicoccum黄体首次报道了Tamarix spp上的Areasonense，Paraepicoccum amazonense，Pleospora herbarum和Pseudocamarosporium propinquum。带有说明和插图。多基因分析表明，Paraepicoccum amazonense应放置在Pleosporineae，Pleosporales，它是密切相关的Camarosporium狭义。对几个标本室标本进行了研究，以说明Tamarix物种上记录的其他真菌物种。关于Tamarix上的微真菌的全面介绍提供，其中包括来自文献以及本研究中鉴定出的数据的列表。本研究中讨论的大多数分类单元的分类位置是基于现代分类学框架的，该框架基于对多基因序列数据的分析。
