Addition to Phaeosphaeria: Eriobotrya japonica a New Host of Phaeosphaeria acaciae

In this paper, we report a coelomycetous fungus that belongs to the family Phaeosphaeriaceae (Pleosporales), associated with the leaves of Eriobotrya japonica in Kunming, Yunnan Province, China. Morphologically, our fungal collection shows similarities to known asexual morphs of Phaeosphaeria, and exhibits pycnidial, globose conidiomata, a pycnidia wall composed of cells with textura angularis, ampulliform to broadly conical, hyaline, phialidic conidiogenous cells and pale brown, subcylindrical conidia that are 3-septate. Phylogenetic analyses of maximum-likelihood and Bayesian posterior probabilities of a combined dataset of SSU, LSU, ITS, and tef-alpha sequence and morphological analysis confirmed that our collection is Phaeosphaeria acaciae. This is the first report of a Phaeosphaeria taxon on Eriobotrya japonica.
