Abstract
The sexual morph recorded here for Lasiodiplodia pseudotheobromae, was collected from dead leaves of Plukenetia volubilis L. (Euphorbiaceae) in Yunnan Province, China. The sexual-asexual connection in Lasiodiplodia pseudotheobromae was confirmed by phylogenetic analyses of combined ITS and tef1-alpha sequence data. This is the first report of a sexual morph with molecular evidence for this species. The important characteristics of this species are immersed to erumpent ascomata, papillate ostioles, cylindric-clavate asci with a short pedicel, well-developed ocular chamber and ellipsoidal to fusiform, golden to dark brown, aseptate ascospores. The sexual morph of this species is compared with other Lasiodiplodia sexual morphs and a comprehensive description and micrographs are provided.
