摘要

已知 Dendrostoma 属栖息在中国和欧洲一些国家与树枝腐烂病有关的树皮上。以前的研究表明，Dendrostoma 的物种更喜欢栖息在木质寄主上，尤其是 Castanea 的物种。在本研究中，我们从中国山东省日照市的板栗（C.mollissima）枯枝中获得了 4 个分离株。通过形态学比较和 ITS-tef1-rpb2 组合序列矩阵的系统发生学分析，发现了两个新种，分别命名为 Dendrostomarizhaoense sp.本文对这两个新分类群与其他 Dendrostoma 种类进行了比较，并提供了全面的描述和插图。

Two new species of Dendrostoma (Erythrogloeaceae, Diaporthales) associated with Castaneamollissima canker disease in China.

The genus Dendrostoma is known to inhabit tree barks associated with branch canker diseases in China and several countries of Europe. Previous studies indicated that species of Dendrostoma prefer inhabiting fagaceous hosts, especially species of Castanea. In the present study, we obtained four isolates from cankered branches of Chinese chestnut (C.mollissima) in Rizhao City, Shandong Province, China. Morphological comparisons and phylogenetical analyses of a combined ITS-tef1-rpb2 sequence matrix were conducted, which revealed two new species named Dendrostomarizhaoense sp. nov. and D.tianii sp. nov. The new taxa are compared with other Dendrostoma species and comprehensive descriptions and illustrations are provided herein.
