Arthrinium, a globally distributed genus, is characterized by basauxic conidiogenesis in its asexual morph, with globose to subglobose conidia, which are usually lenticular in side view and obovioid and brown to dark brown. The sexual morph develops multi-locular perithecial stromata with hyaline apiospores usually surrounded by a thick gelatinous sheath. Four Arthrinium species collected in Kunming, China, are described and illustrated in this paper. Based on the morphology and analyses of ITS sequence data, we introduce two new species of Arthrinium. Arthrinium garethjonesii and A. neosubglobosa spp. nov. are provided with descriptions of sexual morphs and compared with phylogenetically close taxa. Arthrinium hydei and A. hyphopodii are new records on their sexual morphs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
