Pseudofusicoccum adansoniae Pavlic, T.I.Burgess & M.J.Wingf. and P. ardesiacum Pavlic, T.I.Burgess & M.J.Wingf. were collected from branches and twigs of Hevea brasiliensis Müell. Arg. in Phayao Province, northern Thailand. Pseudofusicoccum Mohali, Slippers & M.J.Wingf. is known only by its asexual morph. Here, we report the sexual morph of P. adansoniae based on phylogenetic analyses of a combined ITS, LSU, TEF1 and β-tubulin dataset. The sexual morph is characterized by immersed, uniloculate ascomata, ­cylindric-clavate asci with a long pedicel, a well-developed ocular chamber and short clavate, hyaline, aseptate ascospores, surrounded by a mucilaginous sheath. Descriptions, illustrations and molecular data are provided for the taxa.
