Abstract
Members of the genus Cytospora are often reported as endophytes, saprobes or phytopathogens, primarily causing canker diseases of woody host plants. They occur on a wide range of hosts and have a worldwide distribution. Although several species have in the past been reported from China, the vast majority are not known from culture or DNA phylogeny. The primary aim of the present study was thus to clarify the taxonomy and phylogeny of a large collection of Cytospora species associated with diverse hosts in China. Cytospora spp. were collected in northeast, northwest, north and southwest China, indicating that the cold and dry environments favour these fungi. In this paper, we provide an assessment of 52 Cytospora spp. in China, focussing on 40 species represented by 88 isolates from 28 host genera. Based on a combination of morphology and a six-locus phylogeny (ITS, LSU, act1, rpb2, tef1-α and tub2), 13 new species and one new combination are introduced. The majority of the species investigated here appear to be host-specific, although further collections and pathogenicity studies will be required to confirm this conclusion.
期刊介绍:
Persoonia aspires to publish papers focusing on the molecular systematics and evolution of fungi. Additionally, it seeks to advance fungal taxonomy by employing a polythetic approach to elucidate the genuine phylogeny and relationships within the kingdom Fungi. The journal is dedicated to disseminating high-quality papers that unravel both known and novel fungal taxa at the DNA level. Moreover, it endeavors to provide fresh insights into evolutionary processes and relationships. The scope of papers considered encompasses research articles, along with topical and book reviews.
