Abstract: | Collections of bionectriaceous fungi from different areas of China were examined, in which 3 new species were encountered. Bionectria intermedia is characterized by smooth perithecia, 2-layered perithecial wall, cylindrical to clavate asci with an apical ring, ascospore striations composed of separate warts, and dimorphic conidiophores. Hydropisphaera yunnanensis has hairy ascomata which are cupulate when dry, clavate asci with a simple apex, and spinulose and very narrow ascospores fusiform and constricted at septum. Nectriopsis apiosporae possesses laterally pinched perithecia when dry, 1-layered perithecial wall, rough perithecial surface, clavate asci with a simple apex, spinulose ascospores with 3 septa, and on Apiospora sp. Four species, Bionectria epichloë, B. kowhaii, B. subquaternata and Hydropisphaera suffulta, are reported as new to China. |
