Abstract: | Four new species belonging to Bionectria, Calonectria, Haematonectria and Neonectria on plant substrates collected from nature reserves in southern and central China are described. Bionectria truncata has smooth perithecia of a flattened to shallow discoid apex, clavate asci with an apical ring, and ellipsoid, smooth to
spinulose ascospores. Calonectria dicephalospora is characterized by pyriform perithecia with a warted surface, clavate asci with a simple apex and long, narrow stalk, and
fusoid ascospores with a cap-like appendage at each end. Haematonectria lushanensis possesses warted perithecia which are laterally collapsing when dry, cylindrical asci with a simple apex, and ellipsoid,
spinulose ascospores. Neonectria dinghushanica is distinguishable by subglobose perithecia with a warted surface, clavate asci, and striate ascospores. Morphological features
of these new species are described comprehensively and compared with their related fungi. Neonectria castaneicola is recorded as new to China. |
