Abstract
A new species of Wojnowicia was isolated from leaves of Viburnum utile in Guizhou Province, China. The new species, Wojnowicia viburni, is described, illustrated and compared with similar species. It differs from other Wojnowicia species in its 6-8 euseptate, smaller conidia and lack of setae. Phylogenetic analysis of LSU rDNA sequence data shows that the species groups with W hirta and Ophiosphaerella herpotricha in the family Phaeosphaeriaceae. The genus Wojnowicia is emended to include species without setae. This is the first record of the genus from China as well as from Asia. A key is provided for the four species accepted in Wojnowicia.
