Deskripsi

<i>Torula</i> is an asexual and hyphomycetous genus in the family Torulaceae. <i>Torula</i> species are generally saprophytic. They have a worldwide distribution and abound in humid or freshwater habitats. In order to better understand this genus, we carried out several field collections from Sichuan, China. As a result, we obtained nine <i>Torula</i> isolates from dead woody substrates in terrestrial and freshwater habitats. Based on a biphasic approach of morphological examination and multi-locus phylogenetic analyses (ITS, SSU, LSU, TEF, RPB2), these collections were identified as belonging to seven <i>Torula</i> species. Four of them were new species (<i>Torula chinensis</i>, <i>T. longiconidiophora</i>, <i>T. sichuanensis</i> and <i>T. submersa</i>), and the other three belonged to existing species, though one was found for the first time in China (<i>T. masonii</i>). Morphological and updated phylogenetic delamination of the new discoveries is also discussed. This study provides further insights into our understanding of wood-based <i>Torula</i> species in China.
