Abstract:A new endophytic fungus, Pestalotiopsis castanicola (Amphisphaeriaceae, Ascomycota) on host of Castanopsis carlesii var. spinulosa, was described. Most lateral appendages in Pestalotiopsis lie on the apical cells. While P. castanicola has 2?4 lateral appendages on which lie the septum separating the apical cell and upper median cell. The placement of the lateral appendages in P. castanicola is similar to that in P. montellica and P. jesteri, but the conidial morphology among P. castanicola, P. montellica and P. jesteri has apparent differences. A phylogenetic analysis of the combined sequence data of internal transcribed spacer (ITS), partial ?-tublin (TUB) and partial translation elongation factor1-alpha (TEF) indicated that P. castanicola formed an independent branch in genus of Pestalotiopsis. | |||

Abstract:Only four species of Hypohelion (Rhytismataceae) have been reported worldwide. In the present study, two new species of Hypohelion, Hypohelion bifusiforme and Hypohelion ventricosum, are described on living twigs of Ericaceae from Southwest China. Bifusiform ascospores and intraepidermal ascoma development are two conspicuous characteristics of the two new species, by which they can be distinguished from other species of Hypohelion. By its apically strongly swollen paraphyses, H. ventricosum differs from H. bifusiforme. The phylogenetic position of the two species within Rhytismataceae was analyzed based on the combined sequences of LSU rDNA, ITS rDNA and mtSSU rDNA. Although the other species of Hypohelion and some species of other genera of Rhytismataceae formed a strongly supported evolutionary clade, a resolution on the genus level was not yet possible. | |||
