In a preliminary survey of fungi on Asteraceae in Yunnan Province, China, new fungal species belonging to the family Leptosphaeriaceae were identified, including a new genus and a new species. These fungi have unique ascospore characteristics and molecular data. Additionally, new host records were reported in this study.
In a cursory survey of fungi on Asteraceae in Yunnan Province, China, we report fungal species belonging to the family Leptosphaeriaceae (Pleosporales, Dothideomycetes). Two novel species have remarkable ascospores that are unusual for sexual ascomycetes. Multilocus phylogeny of large subunit, small subunit, and internal transcribed spacer sequence data showed one to be a novel genus, while the other is a new species. Praeclarispora artemisiae gen. et sp. nov. is introduced and is typical of Leptosphaeriaceae, but has unusual fusiform, versicolor ascospores with a brown median cell. Sphaerellopsis artemisiae sp. nov. has scolecosporous ascospores with deeply constricted septa that split into two parts, which resembles S. isthmospora but differs by ascospore dimension and molecular data. In addition, Plenodomus artemisiae is reported as a new collection from dead stems of Artemisia argyi in Qujing City. Plenodomus sinensis is reported as a new host record from Ageratina adenophora. All taxa are illustrated and described based on evidence of taxonomy and phylogeny.
